GREENLAND CORING EXPEDITION

“What do you do if a polar bear comes?” The Finnish helicopter pilot asks this as he is about to take off from a frozen lake in southwestern Greenland to pick up the rest of the science team, leaving Brown University PhD student Billy D’Andrea all alone on the ice. D’Andrea smiles at him to acknowledge the joke, but the pilot isn’t smiling back; it turns out that he has encountered male polar bears venturing this far inland, presumably desperate for a meal. The plight of polar bears provides a dramatic example of the sensitivity of arctic ecosystems to climate change. And while the Brown University science team was interested in understanding the natural variability of climate in this region of Greenland, they were not interested in encountering a hungry polar bear on the middle of an isolated, frozen lake in the arctic tundra…

In April of 2006, a team led by Professor Yongsong Huang and Billy D’Andrea conducted a two week lake coring expedition in the Søndre Strømfjord region of southwestern Greenland, just north of the Arctic Circle. They were targeting a group of brackish lakes in the region, which they had identified as being particularly useful for reconstructing past changes in the climate of the region. Based in part on preliminary work they had published in the journal Organic Geochemistry, which reported the presence of unusual algal lipids in the sediments of the brackish lakes of the region, the National Science Foundation funded an extensive project to reconstruct the temperature variability of southwestern Greenland using the 8,000 years-worth of sediment found at the bottom of the lakes. The unusual algal lipids are alkenones, and they have been shown in the world’s oceans to retain a signal of the temperature of the water in which the producer algae lived. The on-going Greenland project involves (among other objectives) investigating whether alkenones found in lake sediments can be used to quantitatively reconstruct lake water temperature, identifying and collecting the producer algae for culturing experiments, and reconstructing lake water temperature in decadal time steps over the past 8,000 years by examining the alkenones preserved in lake sediment cores. The primary motivation for the research is to investigate the natural variability of temperature and precipitation in southwestern Greenland over the past 8,000 years and to understand the natural forcing mechanisms and climate feedbacks that determine this variability. To reconstruct past temperature, they first needed to recover the sediment cores.

The coring team (which, fortunately, never did encounter a polar bear) included Dr. Yongsong Huang, Billy D’Andrea, Jonathan Nichols (a Brown PhD student), Mark “Kane” McGuire, an undergraduate (class of ‘07) who would eventually complete a senior thesis project connected to this field work, and Dr. John Anderson (a collaborator from Loughborough University in the UK). The team traveled to and from Greenland on a C-5 and C-130 cargo plane, masterfully piloted by the 109th wing of the Air National Guard out of Scotia, NY. While the noise inside a propeller-driven cargo plane made in-flight movies impossible, the cargo net seats and extra leg room more than made up for it… and of course the team could bring all the equipment they needed.

This huge C-130 cargo plane transported the team.

Once in Greenland, the team operated out of a science facility called KISS (Kangerlussuaq International Science Support), from which they relied on an A-Star helicopter, a Hagglund tractor, a pick-up truck, and some long distance trekking to achieve full sediment recovery of 12 lakes in the region over a ten day period. Winds and cold temperatures (0-10 °F) made field work challenging at times, with lake water immediately freezing up the coring equipment, but the team worked extremely well together and were able to overcome such obstacles. The team enjoyed hiking in and out of some of their coring sites, but they preferred the ease and speed of helicopter travel – not to mention the beautiful sweeping views of fjords and frozen tundra these flights provided.

to thaw equipment.

During the April coring trip, the team also deployed five oceanographic time-series sediment traps into two of the lakes. These giant funnels, buoyed at the lake surface and anchored to the lake floor, would collect the sediment that fell to the lake bottom throughout the coming summer. The traps would collect the sediment in ten day intervals into 12 different sample bottles, allowing them to determine when the alkenones were being produced (that is, when the algae were blooming) and inform the team as to when to return to study and collect the algae. In August 2007, Billy D’Andrea and Jon Nichols returned to Greenland to collect the sediment traps with the aid of Dr. John Anderson and other field assistants from the University of Minnesota and the University of Barcelona. Later laboratory analysis of the sediment trap material clearly demonstrated that the alkenones were being produced in late June.

Helicopter travel was easier than hiking to sites
with all the gear.

In June 2007, Huang, D’Andrea and new Brown/MBL PhD student Susanna Theroux returned to collect the algae and to perform lake water sampling designed to better understand the habitat of the organisms. It was immediately clear that the team was there at the right time, as the lake was overtaken by an alga which they had never seen before. Lipid analysis of water filters taken from the lake during the bloom showed enormous concentrations of alkenones, telling the team that these new algae were the ones they were after. The team exploited the natural temperature gradient provided by the lake’s thermoclines to demonstrate that there was a strong temperature dependence on the alkenones produced by the algae in the Greenland lakes. They will use this in situ calibration along with the calibration results of ongoing algal culturing experiments to determine an absolute temperature calibration for reconstructing lake water temperature over the past 6,500 years. Huang, D’Andrea and Theroux will return to Greenland in June 2008 to conduct more limnological sampling and perform on-site culture experiments using the Greenland alkenone producers.

Diligent field and laboratory work has paid off and research associated with the Greenland project has progressed nicely. Two research papers have been published since the beginning of the project. In a paper published in JGR-Biogeoscience, D’Andrea and Huang and their co-authors reported successful polymerase chain reaction (PCR) amplification of 18S ribosomal DNA (rDNA) sequences of haptophyte algae from water filters, surface sediments, and late-Holocene sediments (~1000 years old) from the Greenland lakes. The DNA of the algal primary producer is extremely well preserved in the laminated lake sediments which have been deposited in cold (1-2 oC), anoxic, and sulfidic bottom water. Phylogenetic analyses of the Greenland haptophyte rDNA sequences suggested that alkenones in the Greenland lake sediments are produced by haptophyte algae of the class Prymnesiophyceae. The 18S rDNA sequences from the Greenland samples indicate that the Greenland alga represents a new taxon (this new alga has since been captured by the researchers). More recent DNA work by Theroux, D’Andrea and Huang (presented at AGU in 2007) demonstrates that the Greenland alkenone producers have remained unchanged over the past 6,500 years and that a single alkenone-based temperature calibration can be used to assess temperature variability over that time period.

The second paper, published in Analytical Chemistry, reports a new method for compound-specific hydrogen isotopic analysis of alkenones. Hydrogen isotope ratios (2H/H or D/H) of alkenones preserved in lake and marine sediments hold great promise for paleoclimate studies. However, hydrogen isotope measurements of individual alkenones have not been possible due to chromatographic co-elution of alkenones with the same chain length but different numbers of double bonds. Published studies have only reported the δD values of the mixture of co-eluting alkenones. Huang’s research group developed an efficient procedure to isolate individual alkenones based on double bond numbers using silica gel impregnated with silver nitrate. The chromatographic procedure allows for the first time hydrogen-isotopic measurement on individual alkenones. δD values of specific di-, tri- and tetra-unsaturated C37 alkenones produced by an Emiliania huxleyi culture, as well as those isolated from Greenland lake sediments, differ consecutively by 43 to 65 ‰. These findings suggest that alkenones with different numbers of carbon-carbon double bonds express significantly different δD values and that co-elution of different alkenones may lead to erroneous source water δD reconstructions. Their alkenone isolation approach opens a new avenue for paleoclimate reconstructions using hydrogen isotope ratios of individual alkenones.

The most exciting findings of the temperature reconstructions so far (unpublished, but presented at the 2007 AGU meeting) is that the temperature records from Greenland lakes show centennial-scale variability that corresponds with variability of solar output. However, changes in solar output over centennial time scales are too small to directly impact the temperature of southwestern Greenland so dramatically. D’Andrea and Huang believe that the small changes in solar output cause changes in atmospheric circulation patterns (associated with the North Atlantic Oscillation) which amplify the solar forcing, and result in large climatic changes for southwestern Greenland and other Northern Hemisphere sites. Of particular interest in the southwestern Greenland temperature reconstruction is a large and rapid temperature drop at the time when Viking settlers disappeared from the region. The lake-based temperature reconstructions might help improve our understanding of the role played by abrupt climate change in driving the Norse settlers from Greenland. If confirmed, the findings could shed important new light on the drivers of Northern Hemisphere climate variability, leading to better understanding of Earth’s climate system and better predictions of future regional climate change.

LETTER FROM THE CHAIR(S)

Dear Alumni/ae and Friends of Brown Geological Sciences:

Academic life has a continual rhythm of change, renewal, and growth. As of July, 2008, one of us (Tim) assumed the Chairmanship of Geological Sciences, while the other (Warren) now looks forward to the satisfaction and reflection of a sabbatical. This transition gives us a chance to look at how the Department is evolving, why our Department has been such a special place to study and to work, and to look forward to the development and growth that will continue to make the Department vital and exciting.

IMG_0667.JPG

Incoming Chair Professor Tim Herbert (left) shakes
the hand of former Chair, Professor Warren Prell (right).

We can take pride in having largely passed through a major phase of faculty renewal in the last few years. Although some of the searches started before Warren’s tenure, we have recruited and integrated six new faculty into the Department over the past three years. Jim Russell (ESH), Jessica Whiteside (ESH), and Mike Wyatt (Planetary) joined us in 2006, Greg Hirth (Geophysics) in 2007, and Meredith Hastings (ECI) and Stephen Parman (GMP) in 2008. We’ve added exceptionally talented people, mostly at the junior level, who will expand and strengthen the Department.

Finding adequate research space for all the new and continuing faculty has been a challenge. However, the community spirit and cooperation of the Department has made the Chair’s job much easier. As we’ve gone through this process, we’ve maintained the philosophy of sharing facilities and building concentrations of excellence in our core disciplines; in many cases our recent additions will also take us in new directions with their research interests and their analytical tools. At the same time, we count on the vitality of our emeriti faculty (Hess, Matthews, Rutherford, T. Tullis, and Webb) who continue to be involved in the Department through advising students, conducting research, and participating in Department seminars. 

One of the defining characteristics of Geological Sciences at Brown has been its spirit of collegiality and commitment, which extends not only to connections among our faculty, but to their relations with graduate students, undergraduates, and the staff who work with us. Our new faculty have shown that they embrace this spirit, as they take students to Africa, Utah, the Pacific, or the Antarctic, and as they put their hearts into teaching and mentoring.

Looking ahead, we see an interesting landscape for growth in the Department over the next few years. We have been fortunate that through our planning efforts for renewal of the faculty the University has allowed us to integrate new faculty prior to retirements.Over the next few years, we anticipate that the Department faculty will experience modest growth and that the Department will play an increasing leadership role on campus in interdisciplinary research and teaching. Opportunities include the growth in environmentally-related initiatives (the Brown-Marine Biological Laboratory combined Ph.D. program and the Environmental Change Initiative) and efforts to increase access to sophisticated tools for computing and scientific visualization. 

Much of this newsletter highlights the lives and accomplishments of our alumni. We highly value our connections with alumni and former colleagues and depend on them to inform us on how we’ve done so far as well as offer avenues of advice for the future. As the Department continues to evolve and grow, we count on your continued interest in Geological Sciences at Brown, and welcome your news and commentary.

- Tim Herbert and Warren Prell

Alumni Info 2007-2008

Geoff Abers (ScB ’83): I moved to a Senior Scientist position at Lamont-Doherty Earth Observatory of Columbia University, after eight enjoyable years on the faculty at Boston University. I have moved to Nyack, NY with my wife, Terry Plank, and son Sam. Seismology has me in the field in Washington and Alaska and writing up results from a recent project in Central America with Karen Fischer’s group. Most of my time lately is spent running the MARGINS Office, an NSF-funded support facility that involves me in a wide spectrum of geoscience, and attending very many meetings. 

Jennifer Anderson (PhD ’04): I just completed my third year as an assistant faculty member in the Geoscience Department at Winona State University on the mighty Mississippi River in Southeastern Minnesota. I am enjoying the busy life of a state university faculty member and teach a number of different classes including Planetary Geology, Astronomy, Geophysics, Historical Geology, and an interdisciplinary, team-taught science content course for elementary education majors. I have also worked with a Dance faculty member to design and teach a Science and Dance course called “Time in Motion” which is (indeed) taught in a dance studio and where students investigate the scientific concept of Time. My husband, Jeremy is also enjoying his job at Thern where he designs winches and cranes; but mostly, he races his Ford Mustang and his new 125-cc shifter kart (0 to 60 in 3 seconds, top speed 140+ mph, corners at 3 g’s). If you ever find yourself in Minnesota, be sure to give me a call!

JimConca Jim Conca (ScB ’79): My wife (Dr. Judith Wright) and I published a new book, The GeoPolitics of Energy: Achieving a Just and Sustainable Energy Distribution by 2040. This is a general audience science book, basically a primer for the public and decision-makers. The premise of the publication is that we need a worldwide energy distribution that is about a third fossil fuel, a third renewables and a third nuclear by 2040 of the total 30 trillion kWhrs/year we will be generating by that time, ambitious but doable with the appropriate political will. Folks can check it out at Amazon.com. I am presently Director of the NMSU Carlsbad Environmental Monitoring and Research Center here in Carlsbad, NM. For the last 13 years, we have been monitoring the environment (air, water, soil, people) in a 100-mile radius around the only operating deep geologic nuclear waste disposal site in the world, the WIPP, the Waste Isolation Pilot Project, here in NM (our website is at www.cemrc.org). It is a half-mile below the surface in the middle of a three-thousand foot 230-million year old massive bedded salt deposit that is so tight that 230-million year old sea water is still leaking out (we just isolated some DNA from it - quite exciting).  We are always surprised that no one has heard of WIPP which has been accepting nuclear waste since 1999, both low activity and high activity, just not commercial spent fuel (a non-scientific decision made in 1977 for Cold War reasons). Without reservation, the nuclear repository has been the most successful, and safe, endeavor the country has ever engaged in, with no fatalities, no problems, and even coming in under budget. It has shown the nuclear waste issue to be not much of a problem, that Yucca Mountain is unnecessary if we begin recycling spent fuel, and that the WIPP site has sufficient capacity for over 30,000 years of nuclear waste at ten times the present nuclear power generation. 

Ken Conca (ScB ’82): I was recently promoted to full professor in the Department of Government and Politics at the University of Maryland. I also teach in Maryland’s interdisciplinary Environmental Science and Policy major. I am currently working on a book on the United Nations and global environmental governance. Feel free to contact me at kconca@gvpt.umd.edu

 

JohnCopen John Copenhaver (ScB ’75): My wife Lynn and our two Maltese dogs (Hubble and Gatsby) live in Atlanta, where I am the President and CEO of the Disaster Recovery Institute (DRI). After leaving Brown, I received my Juris Doctor from the University of Georgia and practiced law in Atlanta before gravitating to disasters; I was appointed by President Clinton to head FEMA’s Southeast Region in 1997, where I served until I lost my job in the “hostile takeover” January 20, 2001. I now am happily back in the private sector, where I supervise the international expansion of DRI’s operations. Photo above: at the Great Wall of China.

 

Alice and Abe Abe Doherty (ScB ’95): I got to visit with Alice Post (PhD ‘98) in her small town in the Netherlands this fall, as part of a month-long European film festival tour. I made a short film that was playing in film festivals in 10 countries this fall, so it was a dream-come-true to travel with the film. Alice still wears lots of black. She roasted us chestnuts gathered from her amazing garden and took me on a bike ride through the countryside, past many thatch-roof houses, tiny ponies and pre-historic burial sites of the Huns (the only rocks around). She and her husband Peter both work for Shell. I’m still with the California Coastal Conservancy (now as a project manager for the California Ocean Protection Council) and am having fun making movies in my spare time.

Esther3.jpg Robert Edrington (ScB ’84): As you may recall from last year, we were adopting a little girl from China and seemed to be in perpetual limbo. Well, she’s here (Esther Grace QiuJu Edrington) and what an adventure it was to go and get her. First we (Melissa and I) took the 15+ hour trip to Beijing. The first week was spent touring Beijing and Guilin, as we figured that this was a once in a lifetime trip. Then it was off to Nanning, the Capital of little Esther’s Province. We survived “gotcha day” which is the first day we got to not only see Esther but take her back to the hotel. The paperwork was intense and of course there was the official interview, and more paperwork. Did I mention the paperwork? Then we spent the rest of the week getting to know this little bundle of ours. It was an awkward time in which we were trying to build her trust in us and help her get over the shock of being taken from her familiar surroundings to this new unknown world and these strangers. By Friday we got the official paperwork that made Esther ours by Chinese law and we were off to Guangzhou (Canton), which is where the US Consulate that handles adoption cases is located. And yes, more paperwork; this time it was to process the final visa and immigration details. Also there was the medical exam and swearing in. So finally we were heading to the good ol’ USA. We were a little nervous taking a 10-month old on a very long trip but she was such a trooper. And the really cool part is that she became an American citizen the moment her visa was stamped and she put her foot on US soil and that moment was on the 4th of July, 2007! She’s a real Yankee Doodle Dandy. If anyone wants a more detailed story they can go to esthermakes6.blogspot.com as we kept a blog for the trip and beyond. Esther is fitting in very well with the rest of the kids. Her big brothers find her a great source of entertainment and her big sister loves being a big sister (as up to this point she has been the little sis).

Bob Ettinger (ScB ’01): I have moved to Seattle to teach middle school science, following my college girlfriend (now fiancée!) who started a PhD at UW. The geology is quite impressive out here, but unfortunately it’s not part of the 6th grade curriculum! If there are any geo alums out there who’d like to go look at cool rocks on a hike out here, drop me a line at rsettinger@seattleschools.org.

John Farrell (PhD ’91): As a Brown alum, the husband of an alum (A. Baum '82, MD '85), and the father of two lovely daughters that probably don't have a prayer of getting in, despite the fact that they are both smarter (than me) and have better grades than I ever did, I thought that folks might be interested in the fact that President Bush recently appointed another alum, Dr. Virgil (Buck) Sharpton (PhD ’85) to the position of Commissioner on the U.S. Arctic Research Commission (www.arctic.gov), a federal agency that establishes the nation's goals and objectives for all Arctic research. I serve as the Commission's executive director, and, interestingly enough, the former Chairman of the Commission was George Newton Jr. ('57, BS in engineering). So, there's been a running link. Maybe that's why there is a little town in Rhode Island named "Arctic."

Jeremy Fisher (PhD ’06): I spent most of last year working as a postdoc at UNH/Durham and Tulane while living in the Boston area with my wife, Frances. While it was a productive year, just about all I can remember is a dizzyingly long number of hours commuting. The position did, however, yield a Science publication in November ’07 on Hurricane Katrina, followed by a brief media blitz. In August ‘07, I moved and took a research position at Synapse Energy Economics (www.synapse-energy.com) in Cambridge, MA working on fast-paced projects to understand the practicalities and economics of renewable energy, efficiency, and emissions trading. We are happily living in Somerville.

Karl Flessa (PhD ’73): I’m now the Head of the Department of Geosciences at the University of Arizona and am continuing my research on the Colorado River delta.

Kena Fox-Dobbs (ScB ’99): In December 2006 I received a PhD in Earth and Planetary Sciences from the University of California, Santa Cruz. I spent 2007 teaching several courses in paleontology as a lecturer at UCSC, and working as a postdoc at the Smithsonian. Currently I am studying the biogeochemical effects of termites in African savanna ecosystems as a postdoc in the Zoology and Physiology department at the University of Wyoming. Although it was difficult to leave the Bay Area after 8 excellent years, I am looking forward to future adventures in the Rockies. I can be reached at kenafd@gmail.com.

FranklinGirls.jpg Erik Franklin (ScB ’94): I’m still working for Fast Search & Transfer, the Norwegian Search Engine company I joined five years ago. I’ve recently transitioned into an Alliances Manager role, managing our partners and system integrators who support programs in the US Federal government.  I still live in Arlington, Virginia with my wife Sara, our two beautiful daughters Grace and Caroline and the mutts, Gus and Sierra.

LizFuller.jpg Liz Fuller (ScM ’03): In 2007, I took the Polar Plunge into the icy waters of Chesapeake Bay with 12 sponsors behind me, raising money to support the Chesapeake Climate Action Network. That morning, Fox News chatted with me, and - to my surprise - chose to air the footage! Some of it, anyway. They left out my comments about the science behind climate change. If you’d like to see what the Polar Plunge looked like, with over two hundred people racing into the bay, take a look at: http://tinyurl.com/36qrb4. In 2008, I joined the Peace Corps. I arrived in Morocco on March 4th, but for the safety of all Peace Corp Volunteers, we’re asked not to give our whereabouts in any public document. I can tell you that I’m in the environmental sector, and am learning to speak Tamazight, which means that I’m assigned to a Site of Ecological Interest in the High Atlas or Middle Atlas mountains. If you want to follow my adventures, you can check out my blog at http://innocentablogged.blogspot.com. I can’t update too frequently, since we’re spending more and more time in our villages, and because the computers are a little iffy sometimes, but I do when I can.

 

GilmoreBaby.jpg Jim Greenwood (PhD ’97) and Marty Gilmore (PhD ’98): This has been a great year for us. Jim has been probing Martian meteorites in beautiful Hokkaido and Marty earned tenure at Wesleyan. Best of all, we welcomed Samuel Charles Greenwood into the world on Labor Day, 2007. He’s simply wonderful and gives his parents great joy.

MtLiving_Feb05.jpg Lisa Gaddis (ScM ’81): After four years, I recently stepped down as Chief Scientist of the Astrogeology Team of the U.S. Geological Survey.  It is a huge delight to be able to return to research in planetary science!  Our team is based in Flagstaff, Arizona, and we work on space missions and digital maps of the planets for NASA.  In recent years I’ve worked on the Mars Exploration Rovers mission and I’m now gearing up for the Lunar Reconnaissance Orbiter mission.  I’m primarily a lunar scientist, so I’m very excited about the U.S. and international plans to study the Moon.  (Like many other ‘lunatics’ across the world, I can’t wait to work with the excellent data to be returned by the Moon Mineralogy Mapper instrument headed by Carlé Pieters!)  My husband, James Tyburczy, is a Professor at Arizona State University in the School of Earth and Space Exploration, and we have two children, aged 12 and 10.  Between increased space science activity and growing teenagers, we expect to be very busy in the next few years! Photo: Some of my USGS colleagues who are working on the rover mission:  (left to right) Larry Soderblom, Jeff Johnson, Ken Herkenhoff, and myself.  This photo was published in Mountain Living Magazine in February 2005.

Steve Getty (PhD ’90): I am a Researcher and Science Educator at Biological Sciences Curriculum Study (BSCS) in Colorado Springs, CO. My research and teaching are with about 15 districts around the country (FL, IL, CO, CA) working with K-12 teachers in science and math. I’m developing new types of texts and labs in almost all of the sciences. Projects I’m helping to lead have funding from the U.S. Deptment of Education, NSF, Colorado Math/Science Partnership (MSP), and Los Angeles Unified Schools. But, WOW, human subjects are much messier to analyze than rocks! (you can’t crush, dissolve, and ionize high schoolers in a mass spec, ‘tho some of you might like to….) What’s the most fun about Colorado Springs? The amazing geology, teaching geology here, birding, and mountain biking! (don’t ask – no, I never get skiing).

GonzalezBaby.JPG Eddie Gonzalez (ScB ’94): 2007 was very exciting. This past June, we added a new member to the family, Ruby Pierce Gonzalez. We are very excited to be parents and are tremendously enjoying our time with Ruby. She turned 6 months in December and we are sure she is on the verge of talking, walking, and solving all the world’s problem. Also, this past August we moved to Berkeley, California so that my wife, Betsy, could begin a 3-year seminary program at the Church Divinity School of the Pacific. After 13 years in Washington, DC, I was ready for a change and my wife’s academic pursuits offered a great opportunity to spend time on the left coast. We love living in the Bay Area and have already connected to many Brown friends living out here. As a result of the move, I left my position as Senior Program Director with the National Park Foundation and am now Regional Development Officer for the Student Conservation Association, an organization whose mission is to build the next generation of conservation leaders and inspire lifelong environmental stewardship by engaging young people in hands-on conservation service. I am responsible for finding financial support for our west coast youth and young adult programs including our desert restoration, invasive-species control, fire management, inventory and monitoring, and trail maintenance activities from Washington state to California over to New Mexico. If any alums are working in public land management agencies or agency partners that have a need for youth conservation work, please contact me at egonzalez@thesca.org. I would love to get more youth involved in conservation service work. Before our move west, we started a blog to keep family and friends updated on Ruby and our life in Berkeley. Check it out at www.gonzalezfamilyadventures.blogspot.com. Anyone visiting the Bay Area can contact me on my cell at 703-868-2333. We live in a one-bedroom apartment near Berkeley campus so we don’t have much space to crash but we would love to show you around.

Eric Grosfils (PhD ’96): Life here at Pomona College is going well these days. We’ve been in our new academic building here on campus for about two years, a great space though we continue to iron out kinks; after several years of searching we have added an expansion position to our faculty; and, having recently concluded stints as a GSA PGD officer and as a department Chair, I’m enjoying more “free” time than usual! A lot of that time is spent with Linda and my son Owen (now 4), but I’m also serving as a NAGT Distinguished Speaker this year and happily have had a lot more time to spend working on NASA- and NSF-funded research with students, former students, and other colleagues. As part of this, I am happy to report that I was awarded a Fulbright Scholarship to work with colleagues in New Zealand during the first several months of 2009, where I’ll spend time exploring components of the magmatic systems shaping the Taupo Volcanic Zone.

Jessica Jewell (AB ’04): After working at a geotechnical and environmental engineering firm for the past year and a half, I am now pursuing an ScM in Environmental Sciences Policy and Management. I’m doing an Erasmus Mundus program which is funded by the European Union and is based in four different universities in Europe.  This year I’m studying at the Central European University in Budapest.  The city is a geologist’s playground with naturally-fed thermal spas all of the city and nice hills for hiking and rock-watching just a short bus ride from the city center.  I’m enjoying the challenges and excitement of living in a new country and being in a classroom with students from about 20 different countries.  This summer I’m doing a field course in Greece and then hope to get an internship working on water somewhere in Europe.  After that I’ll be off to Manchester or Lund, Sweden for one more semester of course work before I do my thesis.  I can be reached at: jessica.jewell@gmail.com.  Drop me a line if you’re coming through Budapest.

KJones.JPG Kristen (Ketelhut) Jones (AB ’03): I got married on August 5th 2008.

Daniel Krinsley (MS ’49): I met Richard Ray (MS ’43) at the US Geological Survey over 40 years ago, but we hadn’t seen each other for quite a while. We enjoyed a reunion lunch in November ’07, reminiscing about our careers and eventually our days at Brown. My adventures at Rhode Island Hall (’47-’49) while mapping the surficial deposits of the northern half of the Providence Quadrangle for my Master’s thesis were detailed in the ’93 alumni newsletter. Ray remembered the winter of ’42-’43, when he pursued evening studies huddled in his overcoat on the balcony of Rhode Island Hall. To conserve fuel during the war, heat was maintained only during the daytime hours. In the evening, when the radiator steam came up only once every hour or so, he would rush down to Professor Richard Goldthwait’s office just below the staircase to thaw out and warm up. He also remembered accompanying Professors Quinn and Goldthwait, in the dark evening, along with a photographer and reporter from the Providence Sunday Journal (July 19, 1942), to Copper Mine Hill in Cumberland, where they searched for the tungsten mineral, scheelite, using ultraviolet lamps. As reported in the Providence Journal, it was an evening more notable for the voracious mosquitoes than for any finding of tungsten minerals. These were the good old days?!

Kavita Krishna (AB ’02): Life has been pretty good for me here in New Mexico. I’m working for a watershed restoration group called the Rio Puerco Management Committee (after three years working for the fisheries and education programs on the Santa Fe National Forest). For two years, I coordinated a large EPA grant, under which the group did a variety of restoration projects related mostly to erosion control. Now I’m only coordinating the education and outreach for the group, which I enjoy more. Although I learned a lot about keeping things in order when I was both the project and outreach coordinator, I’m much happier focusing on the outreach/education. The best part about my current job is my once-a-week sessions with local fourth graders doing environmental education activities. I’ve realized through my work experience since college that I’ve most enjoyed the jobs that had a teaching component, and it has always been the education part (whether formal or informal) of those jobs that was most fulfilling. So... the big news is that I’ve decided to go back to school to get a teaching license and a masters in elementary education!

Will Howard (PhD ’92): I was recently on a review panel for the New Zealand component of a multi-nation Antarctic geological drilling project. Coincidentally it turned out to be an all-Brown Geology panel as the members of the panel were Nick McCave PhD ’67, Tom Crowley PhD ’76, and myself. The organizers of the review did not realize the common thread in the panel!

John Humphrey (PhD ’87):  I have continued on as Department Head of Geology and Geological Engineering at the Colorado School of Mines.  The focus areas of the Department include petroleum geoscience, mineral deposits, hydrogeology, and geotechnical engineering.  International field experiences in 2007 included trips to Normandy and South Africa and Namibia.  Plans are in place for trips to Belize and Scotland for 2008.  Anyone interested in the CSM graduate program should contact me at jhumphre@mines.edu.  I live in Boulder and get to ski with Robin Webb (PhD ‘90).

Teddy Keizer (AB ’94): I have been working as the Statewide Organizer of Stand for Children. My main focus has been to set up chapters of volunteers to lobby school boards, city councils, and the State Legislature as a voice for children and schools. We used that base to promote candidates that support education. Successfully targeting and winning ten swing House seats, we were able to bring a majority of pro school Representatives to the State House for the first time in 16 years. What a difference that made for Oregon. We won 260 million dollars more for K-12 public schools, Head Start fully funded for the first time, statewide school nutrition standards, a first and second year teacher mentoring program, and much more. It has been a good year.

John Kwok (AB ’83): My year has been unusually busy and productive. I’ve been fortunate to have borrowed several lenses from Carl Zeiss to photograph Central Park, a Brooklyn street fair and the New York City Marathon within the past few months (I am hoping to share my work with Zeiss in exchange for photographic equipment.). Since June I have been busy combating creationists online at Amazon.com; I strongly encourage those of you who are Amazon.com customers to vote yea on my reviews of Behe’s “The Edge of Evolution” and Dembski and Wells’ “The Design of Life” (Dembski tried to have my review deleted permanently by Amazon.com, but he was forced to relent after I issued him an e-mail ultimatum to have it restored or else. This recent episode is the subject of some discussion over at Panda’s Thumb (www.pandasthumb.org; please look at the December 29, 2007 entry). Last, but not least, I have been working lately at a NYC college in data management. Eventually I also hope to finish a novel that I have been working on for years.

Rose@Dinner.jpg Rosalee Lamm (ScB ’02): After leaving Brown, I spent a year in my hometown of Olympia, WA; got my master’s from MIT in 2006, and am now living in the countryside of southern England, where my partner is learning to build viols and violins. Since leaving MIT and coming here, I’ve been playing a lot of music, learning new skills like sewing and welding, and bicycling around the Sussex Downs. I’m moving back to the US this summer and getting married this July.

Jacques Lord (ScB ’79): The California fires of October 22, 2007 took my house but not my home. We received a reverse 911 call at 4:50 AM and we packed the two cars with children, pets, photos, and papers (and some other keepsakes) and left at 6:00 AM.  I saw our home four days later when people were allowed back in, and it was a pile of ash and debris six inches high with the odd appliance frame sticking out in familiar locations. Only the Weber cooker was still recognizable and standing next to what was once the garage door and potting shed. We were in a hotel -- living 5 people in two rooms – and relocated (for the 4th time) on December 1st to a home that we will rent ‘til we are rebuilt.  I am doing the contracting myself and have already performed disposal of the debris and demolition of the lot, being careful to recycle what I can.  Our architect is my brother Bennett, and I will act as superintendent to the general contractor.  This house will be as LEED certified as we can afford to do. The interesting thing about the fire is this: I left my substantial rock collection behind and it burned.  I thought I would find most of it unscathed; olivine bombs, massive quartz prisms, garnet schist, etc. In fact almost every specimen turned to sand or clay. The quartz, carbonates, feldspars, beryls, topaz, garnets and corundum crystals turned to friable sand or milky kaolinite-like clay. Only labradorite and tourmaline came through with original color and texture and surface appearance. I will never collect rocks again.  We cannot possess them. They should stay in their native state and not my garage.  My old collection returned to dust, and we will too, someday. I’ll make it a point to get out more often and see the rocks and minerals of this wonderful world in their homes, not mine.  I am grateful to be alive and rebuilding.

 

Lin_and_Stein_Team_Coulomb.jpg Jian Lin (PhD ’89): I am Chair of the InterRidge Science Program and Steering Committee of the Woods Hole Oceanographic Institution (www.interridge.org/IROffice). The InterRidge program coordinates and promotes inter-disciplinary and international cooperation in research of the deep-sea geological, hydrothermal, and biological processes at the globe mid-ocean ridge system. In 2007, I continued to collaborate with Ross Stein (ScB ’75) on earthquake research, including study of thrust earthquakes in Algeria, a northern African country. We also co-taught several training courses on Coulomb 3, which is a free and user-friendly tool designed to investigate Coulomb stress changes caused by earthquakes and diking events and is intended for publication-directed research and university teaching (http://www.coulombstress.org). Photo: Team Coulomb (from left to right) Shinji Toda (Japan Geological Survey), myself, Ross Stein (’75, US Geological Survey), and Volkan Sevilgen (US Geological Survey).

Charles Magee (ScB ’96): In April 2007, our daughter Eleanor Jane Magee was born. In June 2007, I left academia to work as a project geologist for Uramet Minerals, a greenfields exploration startup. I now do uranium and base metals exploration in the southern Georgina Basin on a fly-in-fly-out basis from Canberra. Our field areas are 3-9 hours drive from Alice Springs, and the job is awesome.

Ursula Manners (ScB ’00): by way of Jan Tullis – I will defend my PhD (in geophysics at Scripps) this summer and will start a job teaching at the American International School of Bamako in Mali (West Africa) this August.

Jamie Martin-McNaughton (ScB ’03): I have been working in the Washington, DC area for the past two years at Potomac-Hudson Engineering, a small environmental consulting firm, which contracts with the federal government. We perform NEPA-mandated environmental analyses for the Department of Energy and the Department of Defense. I have worked on several Environmental Impact Statements that were recently released to the public, including the Yucca Mountain Geologic Repository-Rail Transportation Corridor, FutureGen, a power plant and sequestration project, and Mesaba, another integrated gasification and coal combustion power plant. I am enjoying my work, writing impact analyses for geology, aesthetics and cultural resources. I am also engaged to my boyfriend of 7 years, and may marry in Acadia National Park.

Rebecca Marvil (ScM ’84): I live in Houston with my husband, Brian Smyth, a gas exploration geologist. I’m still making documentaries and most recently worked on a series for the History Channel called “Tougher in Alaska;” I researched and produced the episode on earth science.

Laurie McDonough (ScM, ‘95): I am still teaching at Dean College and have developed new courses in Meteorology and The Nature of Evolution, in addition to my regular environmental science, ecology and biology classes. At Dean I am also involved in the Writing Across the Curriculum initiative, the “Green at Dean” sustainability task force, Curriculum committee and Retention work team. It is amazing how busy I can be at such a small school. Do you remember those two little kids I had while I was at Brown? Kevin got married on Nov. 1, 2007 on the Mendenhall Glacier in Juneau, AK. He and his wife Karlee are now care-taking a farm in Maine and have their own land on which they intend to build a home and farmstead. Danielle just completed her 4th year at Northeastern in the architecture program. She just completed her second co-op assignment in Seattle, WA, working on the plan for two “green” school buildings. Do you see any patterns developing here? At least I get to travel to interesting places to visit them. When not teaching or helping my kids I live with my two dogs, have a garden in the backyard, read many books and try to spend time on or next to the beach in the summer. I would be glad to hear from you! The best way to reach me is via e-mail at laurie88888@yahoo.com.

sarah.jpg Sarah Milkovich (PhD ’05): Me and my husband Jason Sekanina at Karnak Temple, Egypt, September, 2007. And according to former advisor Jim Head: Sarah and her CalTech colleagues were filmed by CBS News while working on NASA’s Phoenix Mars Lander and also playing at Carnegie Hall in May 2008. Check out the CBS news segment at http://www.cbsnews.com/sections/i_video/main500251.shtml?id=4126258n

Gretchen Miller (AB ’05): by way of Jan Tullis – I will be working for Outward Bound in Maine this summer and then will enter the University of Vermont’s MEd program in the fall.

Edith Moreno (AB ’07): I’m currently a master’s student at The Donald Bren School of Environmental Science and Management at UCSB. It is a two year program that takes an interdisciplinary approach at environmental problem solving. There are various specializations to choose from and I’m focusing my efforts in water resources management. I’m kept pretty busy at the Bren school, but overall I am enjoying my experience here and it feels good to be back in beautiful California!

John Moyle (AB ’60): After retiring from secondary school teaching (Biology, Geology and Astronomy) in New York, my wife, Polly, and I moved to northeast Tennessee in 2003. Shortly after arriving here, I heard about the recently discovered Miocene fossil site in nearby Gray, Tennessee. Since then I have been working as a volunteer in the lab and as a tour leader in the museum, which is under the auspices of East Tennessee State University. This is a unique site with a surface exposure of approximately 5 acres and a depth of nearly 150 feet. So far, entire or partial skeletons have been recovered for over 40 tapirs, 5 rhinoceros, shovel-tusked elephant, camels, a probable new species of red panda, a new species of badger, giant sloth, alligator, peccary and saber-toothed cat. The sorting process also includes the bones of small mammals, fish, reptiles (including turtles), amphibians and plants. The structure is a sink-hole in a limestone stratum. The recently completed museum has excellent educational displays and interactive exhibits. The museum has received over 20,000 visitors in the first 2 months of operation. My Brown University education has served me well!

Dan Murray (PhD ’76): I began a three-year phased retirement cycle at URI, which consists of being off in the fall and on in the spring. Ann (who is on the Wheaton College faculty) is about to do the same, and we will both be completely retired in 2 years. Never- the-less, I seem to be just as busy, between getting back to actually looking at rocks and initiating new programs. In terms of the latter, I am blending a long-term interest in cognitive science with geology. Specifically I am interested in the interface between recent insights in our understanding of the neurological basis for visuospatial thinking and the ways in which geologic experts and students create maps, cross sections, etc. Much of these efforts are an outgrowth of recent and current NSF and FIPSE funding that supports work on geoscience education issues. This year I’ve presented on these issues at a workshop at NAGT, AGU and GSA meetings, and submitted them to the upcoming Cutting Edge workshop on “Teaching with New Geoscience Tools: Visualizations, Models, and Online Data.” On a more personal note, our daughter Jessica (a geophysicist at the USGS-Menlo Park) was married last summer, and a good time was had by all. At this point in my life, I welcome any marriages and births, as happy occasions that stand in counterpoint to the inevitable loss of parents and colleagues. I also, increasingly, look forward to Brown events such as the recent retirement celebrations (is that the right word?) of Paul, Mac, Terry, etc., and the AGU reception, as they provide opportunities to rekindle friendships that become increasingly important as one ages.

Peck_Robin_IPCC_Paris.jpg Jonathan Overpeck (PhD ’86): by way of Tom Webb – Last year’s newsletter showed a photo of and Robin Webb (PhD ’90) at the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report Meeting in Paris. (The IPCC summary for Policy Makers was released on 2/2/07. Go to www.ipcc.ch for details.) Since that time, the IPCC has been named a co-winner of the 2007 Nobel Peace Prize.

Rowan Paul (AB ’00): Naomi Ture (’00) and I were married August 25, 2007 in a redwood forest in Aptos, CA. Josh Schwartz (AB ’03) was one of my best men. I am currently Chief Resident in Family Medicine at Stanford University/O’Connor Hospital, but matched at my top choice for a Sports Medicine Fellowship at University of Utah in Salt Lake City. I had a great time at the AGU in San Francisco. It was awesome to catch up with the geology world and old friends within it!

 

Dawn.Betina.JPG Betina Pavri (ScM ’92): Greetings, friends and colleagues from Brown! We are all doing well. Our son Jason is enjoying middle school and Randy is getting the Orbiting Carbon Observatory ready for launch (http://oco.jpl.nasa.gov). My big news this year is that we successfully launched the Dawn spacecraft in September (http://dawn.jpl.nasa.gov). The photo (above left) was taken just as we had completed the final pre-launch inspection and cover removal for Dawn’s science instruments, two days before Dawn’s launch from Cape Canaveral AFS. The “nosecone” of the fairing covering the spacecraft is visible behind me. I have been working as the Science Instrument Payload Engineer on Dawn since early 2003, following the instruments through design, delivery, integration with the spacecraft, all sorts of post-integration tests, final inspections for launch, and then post-launch checkout. It has been a pleasure to work with Dawn’s science and engineering teams and we are all delighted that Dawn’s science instruments are working so well. Dawn will fly by Mars in 2009 on its way to the asteroid Vesta (in 2011) and dwarf planet Ceres (in 2015). betina@jpl.nasa.gov.

Larry Peterson (PhD ‘84) and Janet (Moll) Peterson (ScM ‘81): We have just reached the 24 year milestone of living in Miami, having moved here shortly after Larry finished up at Brown. Larry assumed the position of Associate Dean of the Rosenstiel School of Marine and Atmospheric Science at the University of Miami this past March, having filled the position on an interim basis prior to that for about ten months. As Associate Dean he oversees the school’s graduate program of some 200 students plus an undergraduate marine science and meteorology program that enrolls nearly 300 majors. Larry continues his research and teaching in paleoceanography and runs a lab known locally as “Club Mud.” Janet is Senior Project Manager at REP Associates, Inc., a full-service environmental consulting company based here in South Florida. Son Corey is now a rising junior at the University of Central Florida and daughter Annie will be a high school junior this fall.

Jon Powell (ScM ’79): I’m still living outside Houston in Taylor Lake Village on an estuary off Galveston Bay. I haven’t done real geology in years, but stay happily busy as an independent advisor on environmental issues to global chemicals and energy industries. My practice focuses on mergers and acquisitions and corporate governance. My wife, Cindy Evans (PhD ‘83, Scripps Institute of Oceanography), works for NASA and is delighted to be back into science in the Space Station program science office after many years in Shuttle operations. My older son, Jacob, just graduated from high school (and, no, Brown was not even on his radar screen), and my younger son, Charlie, who just completed his sophomore year, has recently gotten into interscholastic debate in a very big way. (Advice: “Mamas, don’t let your babies grow up to be debaters…”) I’m in my third term as a councilman in the Village and get a kick out of getting mail addressed to “The Honorable…” When in the area (keeping in mind that Harris County Texas is 150% the size of Rhode Island) please come and visit. We’ll throw some gulf shrimp on the barbecue.

Jennifer Rilling (ScM ’04): My big news for 2007 is that I got engaged in May. John (my long-time beau) and I will be tying the knot in fall 2008. Apart from that, I am still working for the King County Department of Transportation, and I love being back home in Seattle!

Carlos in barbados2.jpg Carlos E. Rincon (ScB ’05, ScM ’06): I am currently working for Environmental Resources Management (ERM), a leading global environmental consulting firm with my base office in Houston, TX. I form part of the contaminated site management group with a focus on the oil and gas industry. The work deals mostly within Texas, although half my time with the company has been spent in Barbados installing ground water monitoring wells.

Peter Rona (AB ’56): I continue as professor of marine geology and geophysics at Rutgers University. I am co-editing an AGU Geophysical Monograph on Diversity of Hydrothermal Systems on Slow-spreading Ocean Ridges. I am working with partners at the Applied Physics Lab/University of Washington on adapting our jointly developed sonar to monitor seafloor hydrothermal flow as part of the regional cabled observatory being developed on the Juan de Fuca Ridge. During this past summer I served as chief scientist on a cruise of the NOAA Ship Ronald H. Brown exploring the head of Hudson Canyon as a dynamic interface between shelf and slope processes.

Mary Visit Illinois 2007 061.jpg Mary Seid (AB ’06): Hiking is fun. For some of us, it is a hobby. As a bedrock geologist for the Illinois Survey, it is part of my job. I already have one map out, and you may view it at www.isgs.uiuc.edu/maps-data-pub/ipgm/pomona-7-5.shtml. If you have questions about the map, please shoot me an e-mail at maryseid@gmail.com. Currently, we are mapping the Pere Marquette State Park area in western Illinois. I have been at the ISGS for over one year. In this time, I have hiked various parts of southern Illinois and have visited the Viper Mine (coal) and the Viburnum Trend in Missouri (lead mine). I hope this finds each of you happy and healthy. 

Cleo Salisbury (ScB ’97): The past few months have been full of life changes. In the summer of 2007, I got married to Tony Lobay up in Tahoe. Our wedding was great, but the honeymoon in Hawaii got off to a bad start -- we managed to time it for a hurricane, an earthquake, and a massive lava delta collapse. Nonetheless, we did get to see a bit of red hot lava, had an awesome walk down the Thurston Lava Tube, and only sustained minor coral-induced flesh wounds from snorkeling. Just before Thanksgiving, I finished up my postdoc at the Scripps Research Institute (working with Prof. Benjamin Cravatt in the Dept. of Chemical Physiology) and moved back to the Bay Area for my new job as a research scientist in the Vaccines and Diagnostics Division of Novartis. Despite living on top of a fault, our new house isn’t very earthquake-safe, but we’d love to have guests anyway!

Connie Sancetta (ScM, ’73): Nothing geological to report, but it looks like I’ve developed a new career of “being an Italian-American.” In addition to translating materials in Italian donated to the Western Reserve Historical Society (including a very exciting collection of old letters which we hope to publish in some way), I am secretary for a newly-established club of people tracing their Italian genealogy, and press officer for the Italian-American Cultural Foundation, a group that tries to raise awareness of one’s Italian heritage, especially for children in Cleveland schools. I’m also in contact with several people in Italy, tracing the history of my grandmother’s family. Geology, genealogy -- not that different, either in spelling or in the research tools (pose hypothesis, collect data, revise hypothesis....)

 

100_0083.jpg Linnea Sanderson (AB ’06): I just finished my 2nd year of teaching, ready to head strong into year 3. I love teaching and living in New York. I started a high school boys baseball team at my school, and that’s going fantastic. This spring I mulched a dog park with my students and ran tests to see how water infiltrated it. The kids observed and made inferences about an outcrop in Central Park (photo, above) just 10 blocks from our school. It showed metamorphism, sedimentation, has great tilting and obvious igneous intrusions. What more could an Earth Science teacher as for?! I went out to see Brian Yellen (ScB ’06) for February break, and I went backpacking on a mountain bike in Arizona for April break.

Christina Schoen (ScB ’77): I haven’t been a practicing geologist since graduating from business school in 1985. Have loved my career in corporate banking and the variety of businesses and localities that I’ve been exposed to. Sometimes a science background comes in handy, too!

Christine Scott Thomson (AB ’93): I am teaching architecture in Milwaukee at the University of Wisconsin-Milwaukee.

jackhammer4.bmp Kristen Soule (ScB ’99): I am still at Brown – a Systems Manager for Sociology now. Recently appointed to the President’s Staff Advisory Committee, and looking forward to a another productive year. In the evenings, I am an instructor for the Brown Tang Soo Do club - a very friendly martial arts group here on campus. Stop by and see us sometime on a Monday or Thursday evening at the PW (which they sometimes call “TF Green Hall” nowadays). I’m living in Providence, fixing up a little house. I’ve decided that power tools are just too much fun; especially when I learned how to use a jackhammer last winter. Warmest regards to all!

Mitch Stark (ScM ’82): “I shall return” to the Philippines this summer, having previously worked there 1995 - 98 for Unocal. Since 1999 I’ve spent nine great years with Calpine managing the Geysers geothermal resource. Now I have accepted a job with Chevron and will be immediately shipped off to Manila, where my boss will be none other than Jens Pederson (PhD ’80). The sleepy little geothermal industry, to which I’ve happily devoted my career, is suddenly booming worldwide, thanks to high energy prices, concerns about CO2 emissions, and demand for renewable energy. Other than work: both kids have been attending Stanford. My son graduated this June, and my daughter is a rising sophomore.  I’m still windsurfing and playing music, but the overseas move will force me to quit the band (www.retroknomes.com). Look for the reunion tour in 2012 or so! mitchsteam@gmail.com

Gordon Start (ScM ’82): I am still a Scoutmaster for Troop 1020, and continue my heavy involvement with Scouting (Boy and Girl Scouts). This year I returned to ExxonMobil Upsteam Research after a year-long project with the Africa Exploration Group. Our children, Nickolas (14) and Caitlin (11), are growing like weeds and are involved in just about everything we will let them work on.

TysonStahl.JPG Amanda Tyson Stahl (ScB ’97): I married Jonathan Stahl on September 30, 2007 in Stehekin, Washington. Beginning in April, we hiked 1,800 miles of the Pacific Crest Trail from the Mexican border through California, Oregon, and Washington. We planned our wedding from the trail and walked to it. Our website, www.trails2wellness.org, promotes the benefits of outdoor recreation for personal wellness, interpersonal relationships, and the relationship between people and nature. The trail journals from our PCT hike are posted on our blog, the “Virtual Campfire” (photos are posted too). We’ve been on an extended road trip across the USA as we seek new jobs and a place to settle down.

Debbie Thomas (ScB ’96): per Jan Tullis - I am an Assistant Professor of Oceanography at Texas A&M, and am a member of the Consortium for Ocean Leadership’s U.S. Science Support Program, which offers a Distinguished Lecturer Series to bring the exciting scientific results and discoveries of the Integrated Ocean Drilling Program to students at the undergraduate and graduate levels and to the geosciences community in general.

Bob Thunell (ScB ’73): My son, Thomas (Brown Class of 2010) was a member of this year’s Ivy League champion soccer team.

 

VeneszkyFamily Dina Venezky (PhD ’98): We spent Thanksgiving 2007 camping in the redwoods near some of San Mateo’s beautiful beaches in my continuing quest to help the kids increase their love of geology. Here’s a picture Stephen took of us at Pebble Beach. Benjamin just finished the school year at a Spanish immersion kindergarten and Nathaniel is in preschool at GeoKids (at the USGS). I still love my work at the survey and recently launched the new Volcano Hazards Program web site. Check it out at: http://volcanoes.usgs.gov.

peter1.jpg Peter Wang (ScB ’83): In 2007 I transferred to another Schlumberger company, WesternGeco, and I am now involved in seismic depth imaging research and engineering. I am also trying to live as green a life as humanly possible, riding my bike wherever I can, which is a formidable challenge in Houston. I think we are now on the hydrocarbon plateau just before we slide down the other side of Hubbert’s Peak. Not very many people here want to believe that, however. pwang01@gmail.com.

Patrick_Rachel_113_07.jpg Catherine Weitz (PhD ’98): This has been another exciting year for us. Rachel was born September 22, 2007 so she and her 2.5-year-old brother Patrick are keeping us busy, both day and night. John and I continue to be members of the science teams for the Mars Exploration Rover (MER) and the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter. Both missions are sending back spectacular data from Mars which we are analyzing for our research. John is the Chair of his department at the Smithsonian Air and Space Museum, which means he’s also spending time doing management. I’m still working for the Planetary Science Institute and enjoy doing work out of my home office.

Brian West (ScB ’92): I changed my position at ExxonMobil earlier this year and am now Regional Studies Supervisor in the Exploration Company. There I manage two exploration projects in the North Atlantic/Arctic and SE Asia/Indochina. I am still based in Houston, but travel more than I would like given my growing family (a 4 year old son and 7 year old daughter). Interestingly, Mike Braun (ScB ’96) recently joined my group and now leads the basin modeling efforts in the regional team.

 

DevreaWexler Devra Wexler (AB ’97): Completing my third year at the Smithsonian’s Traveling Exhibition Service, I have a portfolio of several shows. I’m very excited about the two exhibits I have opening in 2008 (one an art show out of NASA and the other photographs of the planets), and a third in 2009 (photographs of the Grand Canyon). And I have a number of exhibits still on the road. This picture is from the November 2007 opening of “Earth from Space” at the National Air and Space Museum. “Earth from Space” (educational website at www.earthfromspace.si.edu) recently won an award from the USGS, plus we’re hoping to extend the tour through 2012. (By the way if you are interested in finding out if one of our traveling exhibits might be coming to a city near you, visit www.sites.si.edu. We also have a brand new blog!) On a personal note, my husband’s cancer returned the summer of 2007. He is trying an experimental drug and we are very optimistic. We have a lot of support and are getting by pretty well, all things considered. We’re still happy to welcome guests to our house right outside DC (e-mail: dawexler@excite.com), as long as you don’t mind our exuberant two-year-old puppy! A big hello to my professors and fellow ’97 grads.

Ed Williamson (AB ’58): I retired from the Federal Government 10 years ago and have since been dabbling in various ventures. The last, for which I was managing partner, was closed December 2007, and I now consider myself retired-retired starting in 2008. In 2005 my wife (Teresa) and I moved from Northern Virginia to Smith Mountain Lake, where we have a condominium, and a house in nearby Roanoke, Virginia. I intend to remain active in volunteer work and look forward to pursuing some long deferred interests and hobbies.

Winfield Wilson (AB ’04): I am living the dream in Southern California, and can be reached at winfieldwilson@gmail.com.

Pam Wiseman (ScB, ’83): Hi to all! After 6.5 years as Vice President of Operations for an Electronics Manufacturer, I accepted an exciting new position with United Technologies Corporation that is surprisingly taking me full circle. My new position, Director of Raw Materials Procurement for the UTC Division: Pratt and Whitney, has many aspects related to geology! I am responsible for the supply chain and relationships related to the raw materials used in the manufacture of jet engines. These include elements and materials such as Nickel, Cobalt, Platinum, Titanium and Rhenium to name a few. Of course I am most familiar with those elements and alloys whose prices have just gone through the roof! I am involved with every step from the mills to the forgers to the  recycling of finished product. I feel the need to pull out my old Mineralogy text books and consult with my former professors! I may even need to develop contacts at the USGS to understand trends and forecasts for the production and consumption of these key materials. My husband, dogs and cats and I are relocating from Monroe, NY to Cheshire, CT in the near future. We welcome visits from old friends. I can be contacted at pwise96@aol.com.

Kelly Wrobel (PhD ’08): I completed my PhD this past August (with advisor Peter Schultz) after successfully defending my thesis on July 20th just two days (less than 48 hours) after having gall bladder surgery. I have since been working at ExxonMobil’s Research Company in Houston, TX, learning all about “Earth Geology” – as opposed to Planetary Geology (my thesis focused on modeling impact cratering processes on Mars). My husband, Luke, son, Zachary, and dog, Henry, are having a blast exploring the city and finding the ins and outs of Texas life. As part of my new assignment, I will be spending several weeks in the field this coming year learning all about the geology of Utah, Colorado, New Mexico, etc. We are all very happy and loving the warm weather and southern life!

Michael Wysession (ScB ’84): I am on the faculty at Washington University, and had fun this fall creating a 48-lecture video course with The Teaching Company on “How the Earth Works.” Also, with graduate student Jesse Lawrence (now on the faculty at Stanford), we discovered a large region of very high seismic attenuation at the top of the lower mantle above Pacific-rim-subducted ocean lithosphere which could be the result of water that has been brought into the lower mantle.

brianyellen Brian Yellen (ScB ’06): I am currently teaching physical science on the dry side of O’ahu. I love teaching science and I have taken up the Hawaiian pastimes of spear fishing and outrigger canoeing. Last summer, I worked in former Brown/Geo postdoc Julia Hammer’s rock squeezing lab as part of a program to keep science teachers in the lab and excited about research.

 

AileenYingst.JPG Aileen Yingst (PhD ’98): I’ve enjoyed serving as a Participating Scientist on the Mars Exploration Rover mission for the last two years. The mission experience has been intensely rewarding and a great lead-up to what will hopefully be an even longer and more profitable mission - the Mars Science Laboratory mission. I serve as a Co-Investigator for the MArs HandLens Imager on that mission, which is slated to launch in 2009. Much more importantly, Ross and I have worked hard to indoctrinate - er, instill in our children (Joshua, 5 and Rebecca, 3) a love of all things planetary, and I have proof of our success! Recently, Ross made a pastry that was new to our kids. Joshua asked if it would taste like a burger and Ross answered, “It tastes like the planet farthest from.” Joshua then asked, “It tastes like Pluto??” It makes a mom so proud!

 

Victor.jpg Victor Zabielski (PhD ’01): Not much new down here. I got promoted to Associate Professor and am still lord of the domain over the geology department here at NVCC Alexandria (since I am the only full time geology faculty….big fish, small pond, you know). Teaching is going great. I am taking full advantage of my summers off and extending my travels into new realms. I spent a month in Bolivia and Peru last summer and will be heading to Newfoundland this summer with some friends, including Louise Prockter (PhD ’00). We are going to put Louise on a sea kayak and send her out in the bay to see if she can attract some whales. Looking forward to some changes in DC next year.

Julie M. Zaslow (ScB ’96): After graduating from Brown, I spent a year working for Thorne Lay at the Institute of Tectonics at UC Santa Cruz doing research on seismic discrimination of earthquakes versus underground nuclear tests. Although the work was interesting, I decided that the life of lab research wasn’t for me, and went on to work for the next four years at a fast-growing high tech company in Silicon Valley (www.checkpoint.com) as manager of worldwide web operations, where the excitement and pressure were high. After that, I co-founded a vineyard and winery in the Santa Cruz Mountains (www.bigbasinvineyards.com) and did that for another four years. I have since gone back to school to follow my passion for health and nutrition, and am now starting up a private practice as a Nutrition Consultant in Mill Valley, California, across the Golden Gate from San Francisco. I live with my life partner Kenny and our two sweet kittens. I would love to hear from old friends from Brown. I can be reached at juliazaslow@yahoo.com.

2007 UNDERGRADUATE SPRING BREAK FIELDTRIP
by Sargon de Jesus ‘07, ScM ’08

Once again, in the spring of 2007, an excited team of undergrads from the Geology Department made the trip from Providence to a geologically fascinating destination. This year’s destination was familiar territory, but featured new faces. Eighteen undergraduates were led by new faculty member Dr. Mike Wyatt and graduate students Billy D’Andrea and Caitlin Chazen. The group traced the path of the 2000 spring field trip to Zion, Bryce, and Grand Canyon National Parks and Meteor Crater. Funded by late-night group staffing of campus eateries, out-of-pocket contributions, and generous support from the Geology Department and the Rhode Island Space Grant, the trip was immensely successful.

Day 1 kicked off with a before-dawn departure from Providence, with sights set on a campsite outside Flagstaff, Arizona for the first two nights. Upon arriving in Phoenix, our four-vehicle caravan of geologists made its way a few hours up north to an ATV recreation area-turned-campground. We set up shop amid remarkably fresh ATV tracks in the loose volcanic debris (from the nearby San Francisco Peaks). It made for a slightly uncomfortable (physically and mentally) place for the night, but an easy price to pay for what was an otherwise free campsite.

Our first day out in the field featured an extended visit to the Meteor Crater impact site in eastern Arizona. Having Dr. Wyatt as a leader was a privilege for all of us on the trip. In addition to being very familiar with the area (having just moved from Phoenix to Providence), as a planetary geologist Dr. Wyatt could provide insight on the mechanics of a site like Meteor Crater. We identified strata within the crater as being in reverse order on the outside of the crater, suggesting an event such as an impact that could provide the necessary energy. In addition, we learned about the historic importance of Meteor Crater in validating impacts as a legitimate geological phenomenon.

Later that afternoon we visited another two craters, but ones with very different origins: Sunset Crater and SP Crater. These cinder cones and their surrounding brethren gave us a good taste of igneous geology and balanced some of the sedimentary processes we would be seeing later. That same evening, we planned to visit the renowned Lowell Observatory in Flagstaff, but rainy skies put a damper on those plans, and we left Flagstaff the next day unsatisfied.

Our trip to Zion National Park was a colorful expedition through the western part of the Painted Desert, and we had our first sightings of the Colorado Plateau strata. As we climbed up and down section, we familiarized ourselves with the various formations, which would become the major characters in the geologic story that we were about to read: the blocky Kaibab limestone; the colorful Moenkopi and Chinle sandstone formations; the cliff-forming gigantically cross-bedded Navajo Sandstone, to name a few. As we made our way through northern Arizona, we stopped at the famed Horseshoe Bend, where a quick walk from the road leads to a sheer cliff overlooking a deeply incised meander in the Colorado River (photo above). While there was argument about whether or not that would be a good place to BASE jump, we all did agree that it was an opportune time to take a group picture, the first of many more to come. After approximately ten minutes of Billy’s coaching on proper picture-taking technique, a willing bystander snapped a photo of the entire group.

Dr. Wyatt about the geology of Zion.

Pulling off to discuss the sights along the way meant that we drove into Zion after nightfall, which led to a breathtaking sight upon waking at our campsite the next day. Our first exciting day in Zion brought beautiful weather, ideal for doing a couple of hikes around the area. We first hiked up to Weeping Rock, an exposure where the porous Navajo sandstone lies on top of the impermeable Kayenta formation and groundwater flows out of a seemingly solid wall of rock. Several miles up that same trail, we walked through an unnamed slot canyon and encountered evidence for periodic flash floods. Fortunately for us, it didn’t rain that day! We spent the rest of the day exploring other parts of Zion, driving along the canyon floor, and hiking our way to three different emerald pools of dazzling color.

In anticipation of an impending snow storm at Zion, the next day we headed off for a day trip to Bryce Canyon and an up-close view of the uppermost section of the Colorado Plateau strata. At the suggestion of one of the park rangers, we did a four-mile hike down in and out of the canyon from Sunrise to Sunset Point. Amid the twisted conifers and ocher sandstone, we wound our way down the canyon until the hoodoos we saw from up on high were now towering above us. The snowstorm intended for Zion hit Bryce too and soon enough, we found ourselves climbing back up to the canyon rim in full-out snow showers. By the time we reached the top again, beautiful vistas over the canyon were reduced to 30-foot visibility along with a blanket of snow, three inches deep. It was time to return to Zion.

Caitlin, Jena, Ailish, and Devina.

The last leg of our journey was to the granddaddy of them all, the Grand Canyon. Finally, as some of us said, we were about to finish our lifetime homework assignment from GEOL 0220! Naturally, our ambitious outdoor spirit felt compelled to see all the Grand Canyon had to offer. Nearly everyone in the group was on board for our heftiest hike of the week: down the South Rim along the Kaibab Trail and then back up via Bright Angel Trail. We would attempt an ambitious descent down through 300 million years worth of intermittent sediments (the oldest we had seen yet), eventually reaching the 1.8 billion year old Vishnu Schist by the Colorado River. Altogether it would be a 15-mile round trip hike and nearly 4500 feet of relief. Throughout the hike our eyes were constantly overwhelmed, both by the sights off in the distance, as well as by the number of features we could look for up close. At the end of the 10-hour-long hike, we were exhausted (but not dehydrated) and we all appreciated the hot food and warm cups of cocoa back at camp. After spending the next day indulging in some relaxed hiking along the South Rim, we managed to break camp before dawn the day after, amid flurries and a veil of snow to make our way back to Phoenix. With our sights set on Mather Point, towards the East entrance of the park, we drove the vans just in time to join the crowds for a spectacular sunrise over the canyon. Like all of our new experiences on the trip, we were both inspired and humbled by the endless majesty of the Earth.

In addition to Dr. Wyatt, Billy, and Caitlin, the other intrepid travelers on the trip were: Garrett Adler, Alice Alpert, Aditi Bhaskar, Sargon de Jesus, Ben Hudson, Jena Johnson, Jesse Kass, David Koweek, Ailish Kress, Katie McComas, Kevin Neal, Alex Pleet, Josh Stern, Devina Swarup, Christina Tang, Arvid Tomayko-Peters, Tsveta Volen, and Vicky Wang.

We would once again like to deeply thank the Department and the Rhode Island Space Grant for being such faithful and valuable contributors to the field trip. Without their contributions, such an event would not be able to happen. These field experiences are invaluable in exposing Brown geology students to real phenomena and applying knowledge learned in the classroom. Thank you.

NINE HOT DAYS: Notes on the 2008 Spring Break Trip
by Marc Mayes, expected ‘09

During Spring Break 2008, 18 members of the Brown University Geosciences community completed a whirlwind tour of Owens Valley and Death Valley, Califorina. Led by Ailish Kress ’08, 15 undergraduate participants researched geologic sites of interest and helped lead discussions in the field about volcanism, igneous petrology, sedimentary processes and land use management. Perhaps just as important as the geology, the eight-day trip from March 21-29 also helped build camaraderie and friendship.

SpringPhoto1a

shores of Lake Mead.

The fast-paced trip began outside Las Vegas, NV with a stay on the shores of Lake Mead. The man-made reservoir, set in red and pink Precambrian granite and gneiss behind the Hoover Dam, was a beautiful site at which to relax after a long plane flight. Many of us began the weeklong practice of climbing steep cliffs at breakneck speeds, while others hiked around the lakeshore and swam in the chilly indigo waters. The “white bathtub rings” encircling the reservoir’s steep-walled sides, cited in the mass media as evidence for the Western US’s water shortages, gave us all pause. These evaporative deposits were five times taller than our rented Dodge Caravans. The next morning we visited Hoover Dam, and were awestruck both at the engineering feats of the last century and the water management issues that Las Vegas will face in the near future.

From Hoover Dam we drove west and north to Owens Valley. En route, we visited the “Fossil Falls” basalt flow, a cinder-cone barely 30,000 years old, and the Alabama Hills, granite outcrops famous for their distinctive spoon-shaped weathering patterns. The Hills and the vicinity of neighboring Lone Pine, CA have been a favored filming location for many classic Western movies. We also explored the nearby Lone Pine Fault Scarp, a normal fault whose last major rupture in 1872 caused offsets of 7 to 11m. Drill core holes littered the fault scarp, testifying to the fault scarp’s importance to geologists studying fault dynamics. For many of us east-coast and Midwestern students, the Lone Pine Fault Scarp was our first look at a fault active within the past 200 years.

SpringPhoto10.a

“We found it!!” We discovered a
suitable outcrop poking through
the snow at the Obsidian Dome at
Mammoth Lakes only after hiking
around the outcrop.

Our tour of geologic sites in Owens Valley took us from the snow-covered Mammoth Lakes region to the hot, salt-licked floor of the former Owens Lake. Igneous and volcanic features were most prominent, and Professor Alberto Saal dazzled us with his descriptions of recent volcanology in the region. We stopped to see outcrops of the Bishop Tuff, a pink, porous rock made of volcanic ash deposited by an enormous eruption a million years ago. But among all the volcanic features, the Obsidian Dome near Mammoth Lake was one of the most memorable. Though tens of meters high and a mile long, examining the Dome up close required a surprise three-quarter-mile hike; we had to search through snow drifts for a decent outcrop. The outcrop we found was fascinating; the obsidian formed from an eruption only a few thousand years ago, and had inclusions of tuff and other unusual volcanic debris. Though a hindrance to observing the dome, the snow provided us opportunities galore to expel pent-up energy from the morning’s long van rides. Other highlights in Owens Valley included stops at Mono Lake, the ancient Wacobi lakebeds and the Keough Hot Springs.

SpringPhoto12.a

We bid farewell to Owens Valley with a stop at Owens Lake, where hundreds of sprinklers sprayed the dirty white lakebed into the distance to keep the salty soils from blowing excessively. The desolation of the lakebed juxtaposed against the beauty of the jagged, snow-capped Sierra Nevadas was one of the most breathtaking scenes from our trip.

The geological excitement of Owens Valley was only a warm-up for the riveting features of Death Valley. From our campground towards the northern end of the valley, we staged four full days of explorations; the sites we visited gave us the chance to observe further evidence of recent volcanism, as well as beautiful sedimentary features and downright unique geological curiosities! Ubehebe Crater presented us a dramatic example of a maar volcanic feature. The Mesquite Sand Dunes in the center of the valley showed us examples of cross-bedding and mud cracks in the making—and by climbing, skidding and rolling around in the dunes, we tried to leave our own marks in the sedimentary record. Gower Gulch’s laminated lake deposits offered us a chance to practice reading a sedimentary record with distinct signals of tectonic disturbances. At Mosaic Canyon and Titus Canyon, however, we heatedly debated the relative influences of climate changes, changes in weathering regimes and tectonics on the geological features. We spent two to three times as many hours at these stops because their folds, faults, complex fluvial deposits and agglomerations of boulders cemented together with calcite enthralled us to the point where we couldn’t leave without just one more attempt at explaining them.

Many of Death Valley’s features are famous for the mysteries they present. Racetrack Playa delighted our inner geologic problem-solvers as we tried to wrap our heads around the curious “racing rocks.” Rocks ranging in size from centimeters to a couple meters of length seemed to have moved individually along the almost-flat playa, but they had left tracks in the mud-cracked surface that showed amazingly similar trajectories. The articles present in our field guide, as well as our fresh observations, convinced us that ice-rafting was likely part of the explanation for the rocks’ curious wanderings. Among the other mysterious features we visited was a cinder cone split by a fault (aptly named “Split Cindercone”) and a rare geologic feature known as a “turtleback” (the surface of a low-angle normal fault, testimony to the active rifting in this region).

SpringPhoto8a

Group at the Titus Canyon Fault Breccia.

We also visited features that were easily deemed “out of this world.” Death Valley’s incredibly dry climate and strong aeolian weathering leave features in and on rocks such as ventifacts (smooth, elongated holes in weathered basalts) and desert varnish, both of which are similar to rock surface features common on Mars. At Ventifact Hill, a bluff near the famous Artists’ Drive, Bethany Ehlmann explained that remote sensing scientists used rocks from Death Valley to study the differences between altered rock surfaces and actual rock compositions.

By the last day in Death Valley, we had all learned something from the dramatic landscape, but also things from and about each other. Though we were all geologists, geology graduate students, geology or environmental science majors, we had different motivations for studying Earth sciences and different plans for the future. The wisdom, perspective and advice exchanged during hikes, around campfires and on the road with each other may have been even more meaningful, in the long run, than deciding whether the change from sand to pebble-sized particles at Mosaic Canyon meant “more rainfall” or “uplift” in the Death Valley basin twenty thousand years ago. Upon our return to Providence, we agreed that we would remember this trip as one on which we found new questions to ponder and new friends with whom we could ponder them.

Finally, we especially thank Ailish Kress ’08 for her commitment as the undergrad student leader for the trip. Her successes in planning trip logistics and herding 20 undergrads to California and back was no small feat!

PLANETARY DATA CENTER 2007-2008
by Peter Schultz, Director & Peter Neivert, Manager

2007 and 2008 were extremely busy years for the Brown/NASA Northeast Planetary Data Center. In cooperation with the German Space Agency (DLR), the NASA Rhode Island Space Grant Consortium, and the Museum of Natural History at Roger Williams Park in Providence, the Center sponsored and coordinated “A New Perspective on Mars” from September 12 through November 12, 2007. This large exhibition of spectacular large-format three-dimensional images (photo, below) of the surface of Mars was created from data generated by the German Space Agency’s high-resolution camera onboard Mars Express. Ralf Jaumann and Ulrich Köhler of the DLR, who developed the concept for the exhibit, attended the preview opening, which began its North American tour in Providence after appearing at the United Nations in New York. Graduate students from the Planetary Group at Brown acted as docents on weekends, explaining the science behind the images. Thousands of visitors attended this very successful exhibit, which will be traveling on to New Brunswick, Canada, Cornell University and possibly the USGS in Flagstaff, Arizona.

Carle3D.jpg

As it has in past years, the Data Center worked with the Rhode Island School of Design’s Industrial Design Department, facilitating a course in “Design for Extreme Environments: The NASA Studio” underwritten by the Rhode Island Space Grant Consortium. This year students developed full-scale models of a lunar surface module (photo, below), taking into account the requirements and limitations of working on the moon to develop a user-friendly cabin environment. The results of this project were displayed at the RISD Industrial Design Gallery, with image support provided by the Brown Planetary Data Center.

risd.jpg

In addition to annual open houses on Parent’s Weekend and Commencement, the Data Center participated for the first time in a Staff Development Day seminar. The class filled up quickly, and included individuals from all areas of the university, both administrative and departmental. The topic this year was “Planetary Real Estate”, which included images from many recent missions compared to areas on Earth to help attendees appreciate the scale of planetary features.

For the first time since the inception of the Planetary Data Center system over twenty years ago, the Brown Center hosted the annual Regional Planetary Image Facility Directors and Managers Meeting at Brown. Nineteen members from the U.S., Canada and Germany attended the meeting, with a few additional participants via telecon. In addition to discussing administrative issues and future plans, participants visited the Mars 3-D exhibit at the Museum of Natural History (photo, below). Ben Bussey of Johns Hopkins Applied Physics Lab gave a presentation via telecon explaining Planetary Geology and Geophysics Cartography plans for non-US missions, and Professor Carlé Pieters of Brown gave a rundown on NASA’s Moon Mineralogy Mapper (M3) on India’s Chandrayaan-1 mission to be launched in early 2008.

newgroup.jpg

In April 2008, the Brown Lifelong Learning group attended talks in the Data Center as part of their class programming. Jim Head discussed his work in Antarctica as a useful tool for discovering Martian feature and process analogues, Peter Isaacson gave a rundown on the upcoming Moon Mineralogy Mapper (M3) which is a component of the Indian Chandrayaan-1 mission to be launched in 2008, and Peter Schultz spoke about the history and future possibility of massive impacts on Earth.

“Mission Moon: past, present, future” opened at the Museum of Natural History on April 9, 2008. This retrospective exhibit of lunar exploration is part of an ongoing collaboration between the Museum, Northeast Planetary Data Center and Rhode Island Space Grant Consortium to create exhibits that inform and engage the public about planetary science and exploration. In addition to historical lunar images from the eighteenth century to the Apollo era, the exhibit included HDTV footage from the currently-operating Japanese Kaguya mission. The show, which is occurring on the 40th anniversary of the first manned lunar landing, offers museum-goers the opportunity to enter their recollections of the first moon landing in a digital database. The show also includes information on upcoming lunar missions such as Chandrayaan-1 (M3), Lunar Reconnaissance Orbiter (LRO) and LCROSS, efforts in which Brown planetary researchers have crucial roles.

APOLLO 15 COMMANDER DAVE SCOTT VISITS CAMPUS

Astronaut David R. Scott spent several days in the Department of Geological Sciences as the guest of Professor Jim Head, whom he first met while planning and preparing for the Apollo 15 Mission to the Moon in 1971. Apollo 15 was the first mission in which the Lunar Roving Vehicle was deployed, offering the opportunity to explore out to distances of seven kilometers and carry back rock samples from different areas of the lunar surface. Jim served on the geology team that selected the landing sites and traverses, trained the astronauts in recognizing and selecting rock types, worked in Houston Mission Control while they were on the Moon, and analyzed the returned samples.

az.Head.Scott.a.JPG

Many students and faculty members had an opportunity to learn from Scott’s expertise. He is also a collaborator on a Brown research project utilizing the CAVE, Brown’s virtual reality facility, to simulate the conditions for a return to the Moon and a possible voyage to Mars.

The highlight of Commander Scott’s visit was his October 11th address, “Voyage to the Moon: The Apollo 15 Mission to Hadley Rille and the Apennine Mountains”, to a packed house that included faculty, students, RI first lady and science educator Mrs. Sue Carcieri, and a cross section of adults and children from the local community. This lecture constituted the Thomas A. Mutch Memorial lecture offered biannually by the Department. “Tim” Mutch was leader of the Mars Viking Lander Imaging Team and a professor of geology from 1960 until 1980, when he disappeared while climbing Mt. Nun in the Himalayas. The Mutch lecture series commemorates not only Mutch’s accomplishments but also his spirit of exploration.

Commander Scott also took time to discuss his voyage to the Moon with students in Geological Sciences 0050, Jim Head’s introductory planetary science course, and to interact with RISD students who were designing a lunar habitat. He is currently working with students and staff to design a 500-day long mission back to his landing site in the Hadley Apennines region.

Commander Scott is featured in the recently released film IN THE SHADOW OF THE MOON, which “vividly communicates the daring and the danger, the pride and the passion, of this extraordinary era in American history. Between 1968 and 1972, the world watched in awe each time an American spacecraft voyaged to the Moon. Only 12 American men walked upon its surface and they remain the only human beings to have stood on another world.” (Amazon editorial review).

GREENWAY CHALLENGE 2007

Continuing an annual tradition, the Geology department participated in the 2007 Greenway Challenge on September 29, 2007. Grad student Kate Burgess organized a record three teams from the department for the women’s, recreational and corporate divisions of the race, showing the current crowd is an exceptionally fit group of faculty, staff, alums and students! Each 7 member team ran, biked, and kayaked in relay legs totalling 53.6 miles down the Blackstone River Valley. It was great fun on a beautiful fall day with stellar individual performances, no injuries, and only one kayak tipping incident. The corporate team even managed to place 3rd in their division with a time of 5:22:46, the first time Brown has brought home some hardware (a plaque). The team is already thinking about next year.

DAY TRIPPERS
By Hannah Clarkin of the East Greenwich Pendulum  

Fish need oxygen too! Quips a screen-printed fish, fully outfitted with an oxygen tank and mask, as it confidently swims across the back of Brown University Professor Dave Murray’s tee-shirt. Humorous as the cartoon image may seem, it’s hardly a joke. Nearly four years after the 2003 Greenwich Bay Fish Kill, in which about a million Menhaden washed up dead along the shores of Greenwich Cove, lack of dissolved oxygen in the Narragansett Bay is still an issue.

The Bay is healthy when dissolved oxygen levels average around 7 milligrams per liter. Currently, the levels average around 5, dropping below 2 in the furthest reaches of the Providence and Pawtucket Rivers. With a recent history of excess sea lettuce and fish kills, following a summer of beach closures and bacteria warnings, the upcoming summer weeks determine what sort of summer it has been for the Bay.

The Day Trippers
Early in the morning on Tuesday, August 14, Murray, fellow professor Steve Clemens and Bay Keeper John Torgan of Save the Bay are out on the water to do routine testing (photo, right). The morning is sunny and cool, with dry breezes sweeping over the water and a cloudless sky. Launching from Cove Haven Marina in Barrington, RI, they pilot through the Providence and Pawtucket Rivers and the upper bay, measuring dissolved oxygen and salinity. Their device, a Sea-bird SEACAT profiler worth about $20,000 also collects depth, temperature, turbidity and chlorophyll, but their main concern is the oxygen levels.

Today there are two other research vessels collecting the same information in different regions of the bay. This team is just one cell of a group called “The Day Trippers,” a collaborative composed of other Brown University Professors, the Rhode Island Department of Environmental Management, the Narragansett Bay Estuary Program, Save the Bay, United States Department of Agriculture, and the University of Rhode Island, who have been testing the waters in the Bay for the past eight years.

Establishing A Record
“The purpose of this data collection is to take a snapshot of the bay” says Torgan. “After we establish a record, groups like Save the Bay can advocate for standards and changes that need to be made.” Their unofficial numbers yield that the levels are still well below 7, averaging in the upper bay around 3. “If it drops below 4 for a prolonged period of time, that limits the sea creatures viability.”

Data sets, however, don’t always motivate policy makers or the public. “We started testing in 1999,” said Murray. “I told students that the only way we’ll get anyone to pay attention to this is if some dead fish washed up on rich people’s lawns.” Even though numbers pointed to critical conditions for five years, “nothing happened until the Greenwich Bay Fish kill.”

DMurrayDayTripper.jpg

The Composition of the Bay
Estuaries, like the Bay, are composed of pockets of salt and fresh water. “Most of the oxygen in the water is absorbed at the surface. In the winter the water column is about the same temperature throughout” explains John Torgan. This allows the oxygen to mix throughout all depths. “In the summer there is usually cooler salt water on the bottom and warmer fresh water on the top. The surface is isolated from the deep. Oxygen enters through the surface, mixed in by winds and tides.” It doesn’t always make its way to the bottom.

“It’s like Good Seasons Italian Dressing” says Murray. “It’s stratified.” The stratification contributes to some of the Bay’s predominant challenges. In the Narragansett Bay the oxygen essential to the life on the bottom is often trapped in the top layers of the water or depleted by excessive amounts of plankton decay or sea-lettuce growth. “An algae bloom takes place on the surface of the water, when sea lettuce consumes oxygen before it can reach the bottom” says Torgan. “An estuary is a nursery, a birthing place for foundational forms of life; there ought to be some algae, a little green and a little brown, to be healthy. What we have in the Bay is an imbalance.”

Prevention
The prevention of future fish kills can only partially be controlled. Some of the imbalance comes from natural causes. Naturally, salt and freshwater mix poorly. Naturally, bacteria from wildfowl are washed into the Bay during periods of heavy rains. But not all the things that affect the Bay are beyond the control and stewardship of humans. “Right now when it rains it’s like dumping Miracle Grow in the Bay” says Murray. Anything put into the ground in the watershed area will ultimately end up in the Bay when it rains.

The Narragansett Bay takes anywhere from a week to two months to flush. Matter introduced at the north of the Bay will travel out to the sea in a timely matter only in a period of heavy rains. In the dryer summer months, chemicals and bacteria stagnate in the Bay for several weeks, making beach closures common.

Perhaps the biggest change will come to the Bay within the next year, as the Narragansett Bay Commission finishes the Combined Sewer Overflow Project, and the waste run-off that usually enters the Bay untreated will be reserved until it has been properly purified.

Groups like the Day Trippers are establishing a record, measurement by measurement, to mark the recovery or the decline of the Bay. “Like climate change, there are many natural factors involved [with bay pollution],” says Torgan. “But most scientists and lawmakers say that cleaning sewage and storm water is something that is within our control, and something we should be doing.”

NASA MESSENGER Spacecraft Encounters the Planet Mercury

Mercury was last visited by a spacecraft in 1974-1975, when Mariner 10 flew by and imaged less than half of the surface. Now over 30 years later, the first MESSENGER flyby of the planet Mercury on January 14th, was amazingly successful. The spacecraft and all instruments performed flawlessly, the data were played back successfully, and the results are stunning. We saw the side of Mercury that had not been imaged by spacecraft previously and discovered lots of surprises. The students and staff at Brown, and team members across the world, are eagerly analyzing the new data. 

Brown played a major role in scientific operations during the flyby, with many of the department’s graduates in key positions in the mission leadership (e.g., Scott Murchie PhD ‘88, Louise Prockter PhD ‘00, Noam Izenberg ‘89, Olivier Barnouin-Jha PhD ‘98, Greg Neumann PhD ‘93, Maria Zuber PhD ‘86, and several others). Many current Brown undergraduates, graduate students and staff also played a major role. Prior to the flyby, Jim Head led an “away team” of Brown graduate students Laura Kerber and Debra Hurwitz, and research analyst Jay Dickson. They departed for the Applied Physics Laboratory in Maryland, where the mission is centered, for an intense period of operations and data analysis. For the mission as a whole, Jim chairs the MESSENGER Geology Discipline Group, tasked with overseeing the image sequence planning, operations and science data analysis, and coordination with other groups. Graduate student Caleb Fassett led a “home team” of graduate students who remained at Brown to undertake analyses as the data were down-linked from the MESSENGER Spacecraft and transferred to Brown.

A second flyby will occur in October of 2008, then a third, and finally we will insert the MESSENGER spacecraft into orbit around Mercury in 2011. It is a long way to Mercury orbit, but these glimpses from the flybys show that it is definitely worth the wait! 

We are very proud of the Department’s role in the exploration of the Solar System and we hope that this encounter will continue to be a success!

Space Club

The Space Club will be returning to Houston this summer to fly aboard the “Weightless Wonder” and conduct a zero-gravity experiment focusing on fluid behavior in microgravity. These students are continuing the Brown tradition of participation in the NASA-JSC Microgravity University program. Graduate student mentors Brendan Hermalyn (photo, below) and Lillian Ostrach, both of whom have flown aboard the aircraft, are excited to see the team prosper. In addition, the Space Club sends a big thank you to the Rhode Island/NASA Space Grant, which has supported the club in its endeavors as well as provided excellent resources for community outreach.

Dorcas Metcalf, Program Manager of the Rhode Island/NASA Space Grant program said “We continue to be excited at the great projects the Brown Space Club teams have been successfully submitting to NASA for microgravity flight. Each year the undergraduate Space Club team comes up with another great research idea and proposes it to NASA. Actually, we have supported a successful Brown undergraduate team every year since I’ve been with Space Grant. That’s now seven years in a row! That is an incredible success record. Congratulations!”

ENVIRONMENTAL CHANGE INITIATIVE (ECI) EXPLORES ENERGY & ENVIRONMENT

“When an ecologist from Brown University invites an engineer from Iowa to speak, you know something different is going on,” said Robert Brown in the third lecture of the Environmental Change Initiative’s Energy and the Environment series this year. Indeed, one goal of the lecture series was to stimulate further discussion and interaction between the sometimes very separate fields that focus on energy and climate change.

Lectures in the fall series included low-energy, low-cost technology for developing countries by Ashok Gadgil, an engineer at Lawrence Berkeley National Laboratory, who wooed an overflow crowd in MacMillan 115 with his account of an uncommonly common-sense approach to water purification in his native India. Reports of the devastating cholera outbreak there in the early 1990’s inspired Gadgil’s first foray into what became his award-winning technology and he has gone on to launch hundreds of village-owned, operated, and maintained water purification systems. His current project is developing a hyper-efficient but inexpensive cook stove for Darfur refugees that simultaneously reduces ecological damage and violence against women, who are primarily responsible for making long, dangerous trips to gather fuel wood.

Ecologist David Tilman spoke second, combining plenty of hard data with a compelling story about the risks and possibilities for biofuel production. Where it displaces food crops, Tilman warned, the benefits are rarely worth the costs. And the carbon lost through deforestation may never be repaid by biofuel production on deforested land. However, by producing biofuel from high-diversity grasslands on otherwise marginal lands and returning the nutrient by-products to the soil, he showed there are environmentally sound ways to meet a portion of US energy demand with biofuels.

Robert Brown’s talk focused on improving the efficiency of biofuel production, including the use of non-crop feedstocks, redesigning the production process, and reusing fuel-production by-products as fertilizer. He contends that within ten years, one barrel of oil inputs will yield five to eight barrels of biofuel, a much more favorable ratio than the current return from corn ethanol, which is barely above one.

Lectures delivered in the spring semester added an economic angle to the discussion. Kenneth Cassman, Director of the Nebraska Center for Energy Sciences, contested Tilman’s calculations, arguing that production efficiency is increasing rapidly and that the percentage of biofuel production from non-corn sources changes the picture dramatically.

New York Times columnist Tom Friedman spoke directly to the magnitude of the climate change problem and the need for a revolutionary solution. His favorite – after talking with hundreds of researchers: smart grid technology. The formal series wrapped up in April with a talk by Andreas Kraemer, director of Ecologic, Institute for International and European Environmental Policy, in which he surveyed the European and U.S. policy environments – and also put in a strong plug for smart grid technology.

Many of these informative and relevant lectures are now available on video for those readers not within driving distance of MacMillan Hall. Look for the ‘view video’ links on the ECI web site.

VOSS MASS-SPEC DEDICATION

Peter Voss (’68, PhD ’98) retired last year as CEO of a Paris-based, global Asset Management Group. He has long been an active volunteer for Brown, a member of the President’s Leadership Council, a Boston area vice-chair for the Campaign for Academic Enrichment, and now a Trustee (Budget and Finance Committee, Advisory and Executive Committee, Chairman of the Facilities and Design Committee). He has been a generous supporter of the Annual Fund, and this year he pledged $2.2M to establish a research fund for the Environmental Change Initiative, and provided funds to purchase a mass spectrometer for Professor Jessica Whiteside’s new lab.

The ThermoElectron Delta V Plus mass spectrometer is a sophisticated piece of equipment which will catalyze a major advance in paleobiological and biogeochemical research and our understanding of responses to abrupt, sometimes catastrophic climate change in the context of cyclical processes that are a consequence of perturbations in the orientation of the Earth’s spin axis and the shape and orientation of its orbit around the sun. It holds considerable promise for increasing our knowledge of long-term trends in evolution including the biogeochemical consequences of key evolutionary innovations, such as the huge increase in carbon burial rates (and drop in atmospheric carbon dioxide) caused by the evolution and spread of land plants. Without this piece of equipment, Jessica’s research, and that of her students, would be considerably impaired.

On October 11, a reception was held to thank Peter for his generous gift. Peter and his wife, Pam were introduced to faculty and some of the undergraduate students whose research opportunities are being enhanced by the Voss’ contribution.

Geological Sciences Chair Warren Prell, who explains how the
new Mass-Spec will be used to enhance research at Brown.

Within the Department of Geological Sciences at Brown, undergraduate students participate actively in research through independent projects, field work, laboratory experiments, or theoretical computer modeling. Undergraduate students mentored by Jessica are working on a variety of field and lab-based, multidisciplinary projects, including: (1) Analyzing a suite of geochemical proxies through strata of the Green-River Formation of Wyoming, Utah, and Colorado, THE most famous cyclical lacustrine sequence as well as the largest body of oil shale resources in North America. This formation spans more than 15 million years (53-38 Ma) of the warmest, most equable period in recent Earth history and is exceptionally fossiliferous, producing vast numbers of plants, insects, and vertebrates. As the fossil assemblages of these sequences include crocodilians, palms, and other warm climate organisms at presently cold-climate paleolatitudes, the formation has figured prominently in paleoclimate interpretations for over 100 years – and, as such warm climates are likely caused by high levels of greenhouse gasses, provide a crucial model for the current anthropically-mediated rise in carbon dioxide. (2) Analyzing the Caithness Flagstones of northern Scotland and the Orkney Islands, a HUGE cyclical sequence representing tens of millions of years across an extremely interesting time period (~390 Ma) because of the advent of terrestrialization and associated change of locus of global biomass from the oceans to continents as well as the difference in poorly constrained astronomical parameters. (3) Analyzing global carbon cycle perturbations associated with the three major mass extinction events since the advent of animal life. These sequences record the unstable aftermath of the mass extinctions, sequelae of unprecedented magnitude and unexpected consequence that ramified through the Earth system, resetting continental ecosystems to a much more primitive trophic structure from which it took millions of years to recover. This is obviously relevant to our current biodiversity crisis, and these natural experiments from the past are our only real guide to the consequences of our present actions.

The best news is that Jessica and her students are getting some useful insights thanks to Mr. Voss’ gift. The mass spectrometer was successfully installed in her lab, and Carl Johnson, an experienced lab technician, was hired to support her research efforts.

EXTRATERRESTRIAL IMPACT: Likely Source of Sudden Ice Age Extinctions

At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures – giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan.

About 12,900 years ago, these megafauna disappeared from the fossil record, as did evidence of human remains. The cause of the mass extinction and the human migration is a mystery. Now a team of scientists, including Brown University planetary geologist Peter Schultz, provides evidence that an asteroid impact likely caused the sudden climate changes that killed off the mammoths and other majestic beasts of prehistory.

WMammoth.jpg

In the Proceedings of the National Academy of Sciences, the international team lays out its theory that the mass extinctions in North America were caused by one or more extraterrestrial objects – comets or meteorites – that exploded over the Earth or slammed into it, triggering catastrophic climate change.

The scientists believe that evidence for these extraterrestrial impacts is hidden in a dark layer of dirt sometimes called a black mat. Found in more than 50 sites around North America, this puzzling slice of geological history is a mere three centimeters thick and filled with carbon, which lends the layer its dark color. This black mat has been found in archaeological digs in Canada and California, Arizona and South Carolina – even in a research site in Belgium.

The formation of this layer dates back 12,900 years and coincides with the abrupt cooling of the Younger Dryas period, sometimes called the “Big Freeze.” This coincidence intrigued the researchers, led by Richard Firestone of Lawrence Berkeley National Laboratory, who thought that the black mat might be related to the mass extinctions.

So the researchers studied black mat sediment samples from 10 archaeological sites dating back to the Clovis people, among the first human inhabitants of the New World. Researchers conducted geochemical analysis of the samples to determine their makeup and also ran carbon dating tests to determine the age of the samples.

Directly beneath the black mat, researchers found high concentrations of magnetic grains containing iridium, charcoal, soot, carbon spherules, glass-like carbon containing nanodiamonds and fullerenes packed with extraterrestrial helium – all of which are evidence for an extraterrestrial impact and the raging wildfires that might have followed.

Schultz, Professor of Geological Sciences at Brown and an impact specialist, said the most provocative evidence for an extraterrestrial impact was the discovery of nanodiamonds, microscopic bits of diamond formed only from the kind of intense pressure you’d get from a comet or meteorite slamming into the Earth.

“We don’t have a smoking gun for our theory, but we sure have a lot of shell casings,” Schultz said. “Taken together, the markers found in the samples offer intriguing evidence that North America had a major impact event about 12,900 years ago.”

Schultz admits that there is little decisive evidence about the actual details about the impact and its effects. Scientists suspect that a carbon-rich asteroid or comets were the culprits. The objects would have exploded over North America or slammed into it, or both, shattering and melting ice sheets, sparking extreme wildfires, and fueling hurricane-force winds – all of which could have contributed to changes in climate that led to the cooling of the Younger Dryas period.

“Our theory isn’t a slam dunk,” Schultz said. “We need to study a lot more sediments to get a lot more evidence. But what is sobering about this theory of ours is that this impact would be so recent. Not so long ago, something may have fallen from the sky and profoundly changed our climate and our culture.”

The U.S. Department of Energy and the National Science Foundation funded the work.

MICAH CLUSTER
by Scott French

One of the recent and exciting additions this past fall to the research facilities here in the Department was the deployment of Micah, our new Linux-based parallel-computing cluster. While geoscience researchers in need of a parallel number-crunching platform previously had to use the shared computing cluster at the Center for Computation and Visualization, Micah now brings this functionality within the Department. The faculty have been quick to take advantage of this new resource, which currently supports geophysical research performed by Professors Parmentier, Fischer, Forsyth, and Liang, as well as numerous graduate students and undergraduates. Already, multiple applications have been found for Micah’s processing power, including modeling of geodynamic processes within the mantle, modeling of seismic wave propagation, batch processing of seismic data, and more.

MicahCluster.JPG

The cluster itself is composed of eighteen compute nodes, one head node named Micah, and two mirrored storage nodes. More specifically, each of the compute nodes, as well as the head node, is equipped with two dual-core AMD Opteron processors, 8 GB of memory, and a 500 GB hard drive. The two storage nodes boast a similar design, but with Intel Xeon processors, and roughly 7 TB of storage each. The nodes communicate over an Infiniband 4x interconnect for parallel-processing applications and over a Gigabit-Ethernet network for control signaling and file sharing.

The system was assembled by Atipa Technologies, a popular high-performance computing vendor among academic institutions and government laboratories. All in all, this makes for a platform that is both robust and powerful in the short term, and is ultimately fairly “future-proof”.

As the department continues to grow into this new resource, other exciting applications and capabilities will surely be implemented and explored. We are all looking forward to seeing what can be achieved through the union of innovative research and this new resource.

GEOLOGY T-SHIRTS: A BRIEF HISTORY
by Tracy Gregg, ScB ‘90

In 1990, Karen E. Kohfeld (ScB, Geo/Bio, ’90), Matt Carrano (ScB, ’89) and I were eager to have a department-wide field trip to someplace wonderful, but realized that there weren’t department funds for such a thing, nor could we ask the existing pile of majors to pay out-of-pocket for this experience.

We hit upon the idea of T-shirts to raise money for a field trip. The 3 of us brainstormed the T-shirt design, and Matt Carrano (then, as now, a fantastic artist) drew the original design—including the “in Geo Speramus” seal that I note is still being used (below, showing back of shirt, and new design on right).

TshirtShape.jpg UGTshirtShape.jpg

At the time, none of us lowly undergraduates had cars, so we relied heavily on Eric Grosfils (PhD ’96) to drive us to the company in Providence that printed the shirts for us. Eric also collected the finished shirts for distribution at the spring picnic in 1990.

Anyway, it really warms the cockles of my heart to see that the T-shirts are still being sold with the goal of helping undergraduates have great field experiences!

Since then, we’ve all continued our geology careers. Karen Kohfeld is currently Assistant Professor and Canada Research Chair in Climate Resources and Global Change, School of Resource and Environmental Management at Simon Frasier University in British Columbia. Matt Carrano is the Curator of Dinosauria at the Smithsonian Institution in Washington, D.C. Eric Grosfils is an Associate Professor of Geology at Pomona College in Claremont, CA. I’m currently an Associate Professor of Geology at the University at Buffalo in Buffalo, NY. Brown U.’s influence certainly reaches far and wide.

And I proudly wear my Brown University Geology T-shirts in the field!


GEO CAREERS DAY 2008

Once a year the department replaces the usual Thursday afternoon colloquium (an invited speaker discussing cutting-edge research) with a special panel presentation by 3 to 4 undergraduate and graduate alums who acquaint us with the wide variety of jobs and careers open to those with training and degrees in geoscience. Our goal is to highlight jobs and careers other than those in research universities, since our students see examples of those every day.

In the past several years we have had a series of informative and inspiring presentations, highlighting a wide range of opportunities including science writing, museum exhibit development, government work, K-12 teaching, and environmental or geotechnical consulting. The format is as follows: from 4 to 5:30 PM we have brief presentations in MM115 by the alums describing their personal career path and current job situation, with insights into what aspects of their Brown education have served them particularly well. There is time for questions from the audience as well as panel discussion, and then about 5:30 we adjourn to the hallway area directly outside MM115 where Gloria Correra has prepared a fantastic buffet dinner for everyone. This provides a delightful and informal setting in which students can talk with the panelists individually or in small groups.

For the group of 4 alums who came in early February 2008 there was a common thread of using their geoscience training and approach to work on problems of sustainable communities and environments. There was a great turnout of students, and many stuck around for a long time to ask questions and seek advice. A brief summary of the presentations follows.

Jon Zwarg (AB Geol Sci 1997) especially loved the hands-on field aspects of his undergrad geo concentration, but at the time he graduated he did not have a strong sense for what career path he wanted to pursue, so he spent 3 years skiing in Colorado and then 3 years working at a ski center in Connecticut. Those experiences motivated him to get into environmental work. He realized he would need an MS in order to be able to get a position where he could have autonomy and influence, and he opted for the Marine Affairs program at URI, where he did a policy type thesis. He was hired by the RI DEM as a Senior Environmental Planner, working on aspects of ground and river waters and helping to draft new regulatory language. Recently, due to the RI state budget crisis, he was re-assigned to ‘wetlands’ work, a reminder that when one works for government one is subject to political and economic issues.

Jeremy Fisher (PhD 2006) completed his PhD thesis on global change ecology, using remote sensing, and thought of himself as being on an academic career trajectory. He did a post-doc at UNH, on hurricane disturbance modelling, but did not feel connected, engaged or useful. He applied for an AAAS Congressional Science Fellowship and came in #2; he applied to a variety of organizations such as NRDC and EDF but was told they do not hire PhD technical scientists (they hire consultants as needed rather than permanent staff). However, a friend of a friend recommended that he talk to someone at Synapse Energy Economics, Inc (Cambridge Mass), a research and consulting firm specializing in energy, economics and environmental issues; they apply analytical tools to complex resource and policy issues, to inform sound decision making. Jeremy was hired and loves the opportunity to use his scientific knowledge and skills to help analyze societally important topics of global change policy, carbon trading etc. His overall advice: network always!

Bethany Katz French (ScB Geol Sci 1997) loved geo at Brown and especially the scientific problem-solving aspect of figuring out ‘how the Earth works’ - but following graduation she wanted a break from academics so she spent a year skiing. She thought she wanted to get into K-12 teaching, so signed up for Americorps, but found out that kids terrified her. She then worked for a landscape firm and then an environmental consulting firm, but after a while she found herself missing academics. She completed an MS in Environmental Health at UW, intending to rejoin her consulting firm at a higher level. However, she started thinking about the intersection of science and policy and how important it is that policy makers understand science. So she decided to apply to law school, with an emphasis on environmental law. She received her degree from Georgetown about a year ago, and since then has been working for an environmental law firm in Washington DC. Big companies know they have to follow the law and so hire her firm to do back-ground checks on land, etc. She says that most lawyers, even in her firm, are ignorant and uncomfortable with science, and come to her to get input and advice behind the science on any given issue. This position is providing a good learning experience but she will not stay there forever. Her dream job would be either teaching environmental law at a university or working for the EPA were she could hope to eventually become a policy maker.

Ed Delhagen (ScB GeoBio 1983) says that his career has followed a ‘golden retriever trajectory’ (e.g. random!). However there are very strong common threads linking all of his many experiences and jobs. At Brown he first intended to do ES, but decided on GeoBio in order to get a solid understanding of ‘Earth systems science’. He still values the training he got here in critical thinking and communication; he also greatly valued his time at Brown for the wide diversity of fellow students he met and lived with, and for the lesson that if you work hard you can make things happen.

Following graduation his first year was spent - like the other 2 undergrad alums this year - skiing! He wanted to continue to be active in the outdoors, so he travelled all over, doing odd jobs or working short times for gold companies, oil companies etc - he got up to Alaska, all over the Rockies, and many other places, and accumulated fantastic real-world experiences as well as people skills.

After several years he decided he needed further academic training and credentials, with a natural resource focus; he completed an MS at University Michigan dealing with policy and sustainable development, and started thinking deeply about how it might be possible to create a world that truly values all peoples as well as nature. He worked with a number of policy makers, helping them to envision new ways of doing things while using scientific information as the bedrock foundation for policy changes.

For the past 10 years Ed has worked at the Green Mountain Institute for Environmental Democracy, in Vermont. He realized that economic models and systems were driving decisions that did not benefit local communities, so he has invested time building networks and green partnerships of local foresters, farmers etc. His overall motivation has been to transform systems not by making and enforcing new laws, but rather by network formation and consensus building, by identifying points of common good and fostering cooperation rather than competition. His presentation was an inspirational reminder that individuals truly can make a difference in this world!

All of us in the department really appreciate the willingness of our alums to come back and share their experiences, and to provide advice and information about the ‘real world’ that we ivory tower academics cannot give. To all of these alums who have come back to broaden our horizons - THANK YOU!

NSF GK-12

With Mr. Wizard’s World and Bill Nye the Science Guy off the air, who is inspiring the next generation of scientists? That’s an easy question to answer, at least for some Providence public school kids. The NSF sponsored program “GK-12: Physical Processes in the Environment” inspires them to try hands-on experimentation with a number of research topics from climate dynamics in the equatorial Pacific and drought in the interior US to magmatic evolution of martian meteorites. These subjects are taught by NSF Fellows at Brown University.

The GK-12 program is entering its second successful year with three of the seven fellows represented by graduate students from the Department of Geological Sciences and principal investigators including Karen Haberstroh (Engineering) and Geology’s very own Timothy Herbert.

Elementary School conduct a

The Graduate Fellows commit 15 hours a week in planning time and lessons in two Providence elementary schools and two high schools. The program also includes opportunities for Providence teachers to work in Brown labs over the summer.

This year’s fellows have spent the summer learning teaching methods along side Brown’s Master in Arts in Teaching (MAT) students. They practised their skills during the 4-week Brown Summer High School course, centered around the question “What Genes Make Us Human?”.

PosterSession1.jpg

Highschoolers present their poster on cloning at the
end of the 2008 Brown Summer High School session.

Some valuable lessons were gleaned by the fellows, including the fact that teaching students at multiple academic levels and handling controversial issues in the classroom (example: where does religion fit into discussions on genome mapping?) can be a challenge. As they prepare to incorporate these lessons into the Providence classrooms this fall, the fellows will ensure that this next generation of kids will first encounter air pressure through the timeless egg-in-the-bottle experiment introduced in the 1950’s by Mr. Wizard.

The geology department will also continue its voluntary science outreach with the local Vartan Gregorian elementary school by “adopting” the 2nd grade classrooms and providing exciting science opportunities such as dinosaur excavations with Professor Jessica Whiteside and volcanic explosion demos with Ph.D. candidate Ashely Nagle.
