Letter from the Chair

In the fall, we get to celebrate one of the many transitions in academic life: the arrival of a fresh-faced crop of freshman to campus and new graduate students to our Department. We’re also fortunate that the Department can welcome three junior faculty members this year. Ralph Milliken (Ph.D. ’06) joined the department as an Assistant Professor in June of 2012, Baylor Fox-Kemper joined us in January, 2013, also as an Assistant Professor, and Jung-Eun Lee joined us in July 2013 as an Assistant Professor. As you will see elsewhere in this newsletter, Ralph is spending much of this semester living on Mars time as the first data arrives from the new Mars Curiosity rover. Baylor also brought an exciting academic program with him - in this case by allowing the department to move more deeply into fundamental questions on oceanography.

But at this moment, I wanted to ask all of you to recognize the career of one of us poised on the edge of retirement (but not inactivity!). It’s hard to believe, but Jan Tullis moved to Emeritus status in July, 2013. We’re confident that Jan will continue to play an important role in advising undergraduates and promoting excellence in teaching in the Department. But this seems like a good time to say how lucky we’ve been to have Jan as a colleague, friend, mentor and inspiration.

It’s hard for me to overstate the impact that Jan has had on the Department’s culture of teaching and advising. As many of you know first-hand, Jan transforms the life of many, many undergraduates who come into her GEOL-0220 (that’s Geo-22 for many of us!) course. Within a week she’s learned the names of all 80 to 100 students, and she’s soon knocking them out with the clarity of her lectures and the energy with which she invites them into the magic of earth sciences. Anyone who’s taught a reasonably large class knows how impossible it is to obtain rave course evaluations consistently from a heterogeneous group of students. Yet Jan receives these routinely. Her example is contagious for the rest of our faculty. Who would not want to try to capture some of the same enthusiasm? Jan shows us that it’s there, if one is willing to prepare, and distill, and infuse one’s teaching with enough energy and insight. I have no doubt that the high reputation we have in the University, as THE science department that commits itself firmly to excellence in teaching and mentoring, goes directly to Jan’s work.

Most people who go through the Department are also aware of how deeply Jan touches students and colleagues outside the classroom. I rarely pass Jan’s office without seeing a student in her office, bent over with Jan in conversation. She’s a tireless advocate for our students in many aspects of their lives. Jan also plays a central role in the Sheridan Center for Teaching and Learning, which helps to train so many of our graduate students to become effective communicators and teachers.

On June 15, 2013, over 100 alumni, faculty and staff came together to celebrate Jan and her profound contributions to teaching and mentoring. You can read more about the celebration in this newsletter.

As always, we hope to hear from you throughout the year.

Updates from the Class of '43 to the Class of '12

Class of 1943:

Dick Ray, ScM writes: After receiving my degree in 1943 I  joined the U. S. Geological Survey spending that summer mapping areas of old copper/iron deposits in southeastern Alaska. Before the next field season rolled around I was considered too young and healthy not to be in the military service, so I volunteered for the U. S. Navy just before the Army draft could catch up with me. I spent my ocean time on Destroyer Escort 195 (USS Thornhill) both in the Atlantic and Pacific. On my release from the Service (Lt. jg) I immediately rejoined the U. S. Geological Survey working the summer field seasons in various parts of Alaska. I had always wanted to join the academic world but needed further academic credentials to do that. So I reentered the student world at The Johns Hopkins University, receiving my Ph.D. in 1950. The USGS allowed me to use a three-season study of gold mines and surrounding areas in southern Alaska for my dissertation. Because I was enjoying my USGS work I chose not to test the academic waters for employment. However, as with many organizations there often come management changes and by 1960 my work at the USGS was no longer as enjoyable as it had been earlier. So at this point in my career I moved to the National Science Foundation where I was Program Director for Geology for 15 years. I got to know the academic world  and the academic world got to know me because I had government funds to disperse for geologic research! My government work terminated in 1975 when I chose to take early retirement. I was now ready for the academic world. I thought I had arrived at the point where I always wanted to be – either in a teaching capacity or management role. On reflection, however, I decided that a move to the educational world after 40 years in the Washington, DC area would be a monumental one for my family. I felt such a move would not only be disruptive to their lives but very inconsiderate and unfair to them. So I opted to continue my career as a staff officer for Board on Mineral and Energy Resources at the National Academy of Sciences in Washington DC. I spent seven years in part-time employment at the Academy at roughly 2/3 time until 1982. After my “second retirement” I took up landscape painting as a hobby and also began playing a lot of tournament bridge. My painting activities essentially ended when my wife became ill. I am still playing a lot of bridge but in general my life is rather humdrum. I go to bed late, watch old movies on TV, get up late, eat a lot of frozen dinners and do a lot of thumb twiddling. My existence is pretty much humdrum but at nearly 93 I am not complaining. If there are still any other old fossils of the early 1940’s still out there I’d be pleased to hear from them.

Class of 1952:

Bill Outerbridge, AB writes: December 1, 2011; I was given an award for service to the Commonwealth of Kentucky, specifically for geologic maps done between 1960 and 1978 and landslide studies done between 1978 and 1981. It appears landslides I forecast actually happened. June 1, 2012; Outerbridge, W.F., 2012, Age Relationships Based on Single Crystal Zircon U/Pb Ages, Pennsylvanian, Central Appalachian Basin, Eastern Kentucky, USA: Southeastern Geology, v. 49, n. 1, p. 1-11. Several volcanic ash beds occur in the coal measures of eastern Kentucky. Agesdetermined from some of these ash beds provide a basis for revising our concepts of the timing and development of the Appalachian coal basin.

Class of 1953:

Larry Lundgren, AB writes: I begin as I did last year, since I am hoping for at least one response to a question up front: Do you, dear geologist, know what Ground Source Geothermal (GSG) is? I ask because it is through GSG that geology is still part of my everyday life. So I begin by showing you how I am reminded every day of my life by looking at my neighbor’s yard of one of GSGs benefits –you can neither see nor hear it. For comparison I give you a wind turbine I visit when I am out running. I like that too but many of you do not.

GSG is a basic renewable energy technology here but you will never read about it in the NYTimes and I see no Brown geo course where it might be mentioned. FYI my neighbor’s GSG has been heating his home for 8 years without interruption just as my renewable energy system (distance heating fed by hot water heated by burning municipal waste). No landfills, no ground-water contamination. So why do you dear reader, all one of you, love the oil or natural gas burner so much?

My message is then, that if you are a one-time geology major now retired you can contribute on any one of wide variety of fronts and, if you do so, your life will become perhaps even better than it was before.

I have my own Enkla firman (Simple Company), Right English, in which the work consists of translating medical research manuscripts from Swedish to English and reviewing manuscripts already written in English. True this opportunity is only available to you if you are fluent in a language other than English and that language is one in which scientific manuscripts are written. Doing this is very stimulating and rewarding psychologically. Perhaps I should explain that the path to this was that I left hard rock to become an Environmental geologist. That led to epidemiology (think Chernobyl, radon, ground-water contamination, acid rain effects) and then to becoming Adjunct Professor of Environmental Medicine at the University of Rochester School of Medicine. Now the manuscripts flow in. Always exciting.

I am still playing trumpet in Angsars-Missionskyrkans blåsorkester (Ansgars church – Mission church wind orchestra) as my NYT comment ikon will show you in the form of my Bach Stradivarius trumpet if you read Times comments on, for example renewable energy. We play a lot of American music in that orchestra even the Coffee Song if you are old enough to know what that is.

Central to my life and something I recommend to every retiree is working with refugees at the Red Cross, for me here in Linköping. Two to four days a week, I spend several hours to help refugees from everywhere but nowadays mostly Somali born (see my blog), to learn Swedish or to help them with their homework. The best is actually to sit with 5 or 6, each from a different country and just talk. I have described that experience in a New York Times comment on Michael Chabon’s story about small utopias (Times Magazine 30 September) since the Red Cross coffee room and meeting place is a “small utopia”.

I close by showing you one of the great things in my life which one might describe as the result of intercontinental marriage between me and then Professor Ann Frodi, born in Sweden of an American mother and Swedish father. Ann was Professor at Rochester when I met her but we are all in Sweden now where I commute back and forth via Bus4You between Linköping and Göteborg.

I do not do birthdays but my 80th was an exception so Ann did a dinner for me on her island with our almost universally musical friends and then to top that off our daughter Annika did a performance for me (us) using her newly acquired skills as a Tissue performer. Ankan (Ducky as she is often called) has university degrees from the University of Vermont and University of Gothenburg (3 degrees) and thanks to living in two countries now speaks 5 languages, one more than her mother and 3 more than me. That was not enough so she has added what you see below.

On my 80th birthday I walked into the climbing gym in Göteborg, and heard first Charlie Parker and Dizzy Gillespie, an auspicious beginning. Next was the opening of Olive’s 1996 You’re Not Alone (see my blog) and there was Annika high in the sky performing for me and Ann. I show you a pic from that performance and another to show the latest. 

That is Ann and me under Annika at the end of that performance, concluded by her playing Happy Birthday on her flute high above us, but right-side-up. And the latest is upside down hanging from the legs of her Brazilian teacher, Jailton. Never a dull moment.

Annika and I also run in as many races as Team T and H.

Blog at where you can tell me if you know GSG  and even my very basic (only in Explorer) to see the immigrants who came to Massachusetts and Rhode Island and account for me writing this from Sweden.  A former hard rocker who switched as you learned above. Larry Lundgren [email protected]

Class of 1956:

Peter Rona, AB continues as professor of marine geology and geophysics at Rutgers University. He leads the COVIS (Cabled Observatory Vent Imaging Sonar) project with NSF support which acoustically monitors flow and flux of hydrothermal venting in a hydrothermal field on the Juan de Fuca Ridge with an innovative sonar connected to the NEPTUNE Canada Cabled Observatory, the first such observatory on an ocean ridge. He works collaboratively with NOAA's Northeast Fisheries Science Center on exploration of the giant Hudson Submarine Canyon to determine the role of conditions in the canyon in supporting regional fisheries. He serves as a consultant to the International Seabed Authority on mineralization on ocean ridges as deep ocean mining for polymetallic sulfides approaches.

Class of 1962:

Randolph Steinen, AB '62, PhD '73 lives in Rhode Island and sends this update: I have been volunteering at the Connecticut Geological Survey for the past 6 years. Now I will try to volunteer at the RI Geological Survey. Tune in later for the results.

Class of 1965:

Charlie Shabica, AB writes: Although retired from teaching Earth Science and Coastal Engineering, I’m still working on sustainable shore protection systems. Most of our projects are in the Great Lakes; close to home. We’re also working on a new “Green” marina located on the Gulf shore of southern Belize. It’s nice to get out of Chicago especially in the winter.

It’s a location just south of Northwestern University that has been sand-starved (no beaches) for decades. The other is the layout for the marina in Belize that’s designed to improve coastal water quality.


Class of 1966:

David Schwartzman, MS, PhD '71, writes: This is my first news as an alum, better late than never! I retired as of last June after 39 years on the faculty, now Professor Emeritus, Howard University. 

I am still active in research, with recent focus on climate and energy issues, as well as continuing interest in the long term carbon cycle, coevolution of life and climate as well as origin of life (see you at Goldschmidt 2013). My paperback update of Life, Temperature, and the Earth (Columbia University Press) appeared 10 years ago, still worth reading. I have several recent publications in Capitalism Nature Socialism. My website with my older son Peter is I am active in Green Party and its local affiliate, the DC Statehood Green Party. My campaign website from last November and previous races is: My older son Peter Schwartzman is director of Environmental Studies at Knox College, Galesburg Illinois where he is an Alderman, leading his community in urban farming and renewable energy. My younger son Sam Junge is a leader of Portland Solidarity (Oregon) where he works in a homeless shelter for youth. My email is [email protected]. My favorite quotation: "Be as radical as reality itself".

Class of 1969:

Davis A. Young, PhD has kept busy since retirement in 2004 from Calvin College where he taught for the final 26 years of his 36 year college career. In 2009, he was given the Mary C Rabbitt History of Geology Award by the Geological Society of America Davis recently wrapped up a five-part series on The Origin of the American Quantitative Igneous Rock Classification that was published in Earth Sciences History. The classification, best known today for the CIPW norm calculation, was published in 1902 and was the brainchild of Joseph P. Iddings, Louis V. Pirsson, C. Whitman Cross, and Henry S. Washington, four of America's greatest petrologists in the pre-Bowen era. All four were members of the National Academy of Sciences. Since retirement he has published three books, the most recent of which is Good News for Science: Why Scientific Minds Need God, a challenge to science professionals, teachers, and students to make a serious investigation of Christianity. Davis and his wife have been living in Tucson, Arizona, since retirement.

Class of 1972:

Greg Mountain, AB writes: I've been rather quiet in my Alumni connections back to Brown, though I've worked on occasion with some of the faculty, Warren Prell in particular, and I've enjoyed the many newsletters etc. that have been sent my way. Your latest request for info brought to mind that some might find interesting a 5-min video made about an offshore drilling expedition for which I was CoChief Sci back in 2009. As some who follow this line of work will know, the Integrated Ocean Drilling Program for years circled around the challenge of drilling for climate history, etc. on continental shelves, and finally took the plunge offshore New Jersey, with great success. Our scientific results are due to come out in the online journal Geosphere over the next several months.

On an entirely separate issue -- I'm taking over as head of the alumni board for my graduate earth science school (Lamont-Doherty Earth Observatory of Columbia Univ.) and I'm curious: does the Geology Dept have any type of alumni organization (distinct from the general and very active Brown Alumni Assoc) ? If so, how is it structured, who are the alums most involved, and is there an actual 'alumni board' with a 'mission statement' type of document that outlines what the board aims to do? One of my first actions as board president here is to invigorate our members and give them a set of 'marching orders' so they know what is expected of them.

Gary Robbins, ScM: On October 12, 2012, Dr. Gary Robbins, Professor of Geology, Dept. of Natural Resources and the Environment, received the Licensed Site Professionals Association (LSPA) of Massachusetts 2012 Contribution to Practice Award at their annual meeting. The LSPA is a non-profit organization of environmental professionals and others (attorneys, laboratory personnel, contractors, etc.) involved in the management of hazardous waste sites, with nearly 1000 members.  Dr. Robbins is well known for his research work at the University of Connecticut related to improving site characterization methods at sites that have ground water contamination.  Dr. Robbins received the award ”in recognition of outstanding contributions and advancing the profession”  through helping to train LSPA members in state-of-the-art techniques related to environmental assessment.  In addition to developing mortar and brick courses, especially hands-on field courses, he pioneered on-line training courses in Massachusetts and Connecticut using simulations to provide real world training in virtual space.

Class of 1975:

Suzanne Mahlburg Kay, PhD: Suzanne is the President of the Geological Society of America effective June 1, 2013.

Ross Stein, ScB writes: Brown Geo junior Jeremy Shar spent the summer working with USGS Geophysicist Ross Stein '75 on an earthquake physics demonstration apparatus, QuakeCaster. Jeremy turned the one-dimensional spring-and-rider system into a two-dimensional earthquake interaction apparatus that they have dubbed, Fishnet Stocking Stress. That's because the sliders are magnetically attached to a fishnet stocking stretched in a frame that is pulled by a casting reel over a high-friction surface. The sliders undergo stick-slip and interact as a function of their mass and proximity in ways that are both predictable and chaotic. Ross has since used Fishnet Stocking Stress in talks at UCSC, Univ. WA, and the USGS. Ross hopes to bring Jeremy back next summer to perform experiments and create build-and-buy instructions, and submit them to publication. Ross thanks Jan Tullis for sending him yet another great Brown Geo student.

I don't really have much of an interesting story, but to tell you all of the interesting places that a geology degree can take you, I am not selling business jets for Cessna aircraft. I lead a team of salespeople responsible for jet sales in New England and the Great Lake state.

Class of 1976:

Joel Scheraga, AB: Dr. Joel Scheraga is the Senior Advisor for Climate Adaptation in the U.S. Environmental Protection Agency’s (EPA’s) Office ofPolicy in the Office of the Administrator. He is leading EPA's efforts to develop and implement a Climate Change AdaptationPlan to ensure it can continue to protect human health and the environment even as the climate changes. He also represents EPA on the federal Interagency Climate Change Adaptation Task Force. The Task Force was established by Executive Order in October 2009 and charged with developing recommendations for President Obama on how the nation might adapt to climate change impacts.

The EPA released its draft Climate Change Adaptation Plan on February 7, 2013. The plan was produced by the Cross-EPA Work Group on Climate Change Adaptation, chaired Joel. As stated in the EPA “Policy Statement on Climate Change Adaptation,” signed by Administrator Lisa P. Jackson in June 2011, climate change can pose significant challenges to the EPA’s ability to fulfill its mission. The EPA must therefore adapt to climate change if it is to continue fulfilling its statutory, regulatory, and programmatic requirements. The unprecedented EPA Climate Change Adaptation Plan provides a roadmap (including Agency-wide priority actions) for how the Agency will anticipate and plan for future changes in climate and incorporate considerations of climate change into its programs, policies, rules and operations to ensure they are effective under future climatic conditions.

Class of 1979:

Jim Conca, ScB writes: Forbes asked me to do a weekly blog in May on energy and nuclear. I'd love to hear what everyone thinks of it. It's a lot harder than I thought and definitely is making me feel old!

Adam Schultz, ScB: Adam Schultz. NSF (EarthScope and Marine Geology & Geophysics) released funding for our MOCHA project. This stands for Magnetotelluric Observations of Cascadia using a Huge Array. This is the most ambitious onshore-offshore magnetotelluric (electromagnetic) imaging experiment yet undertaken, and has OSU's National Geoelectromagnetic Facility as the lead (Adam Schultz is PI of the NGF), with collaborators from the University of Oregon, Scripps Institution of Oceanography, and the USGS. We will instrument most of western Oregon and part of SW Washington and extend the arrays offshore to image the electrical structure of the crust and upper mantle in high resolution, with a specific target of detecting the distribution of fluids rising from the subducting Juan de Fuca plate. These fluids may play a key role in moderating Episodic Tremor and Slip, a slow earthquake type phenomenon that may itself be important in redistributing stress within this megathrust seismic hazard area.

We also recently were awarded NSF funding (GeoPRISMS and EarthScope) for a large scale, high resolution magnetotelluric study of the southern Washington Cascades volcanic arc including Mt St Helens, Mt Adams and Mt Rainier. I am PI of the magnetotelluric study, with collaborators from the USGS, and seismic collaborators from University of Washington, LDEO and Rice University. We will image the details of the volcanic connections between the upper mantle and the surface volcanic expressions, and investigate the possibility suggested by earlier studies that there is a large-scale mid-crustal magma accumulation in this area.

Both MOCHA and the SW Washington Cascades field work will take place during 2013-2014.

The National Geoelectromagnetic Facility has recently completed two marine electromagnetic surveys offshore Reedsport and Newport Oregon in support of wave energy development. Our work at Reedsport in August was a requirement for Ocean Power Technology to gain their permit to install commercial wave energy converters at Reedsport, which is the first commercial wave energy electric generating facility in the US. The permit was granted immediately following our survey. The Newport work was completed last week, and was carried out to detect electromagnetic fields emitted from the Northwest National Marine Renewable Energy Center's wave energy electric grid simulator testbed, which was operating with a scale size commercial wave energy converter attached. Our work at these sites was carried out in collaboration with a colleague from SAIC. Our lab is currently completing a new generation combined ocean bottom electromagnetic field/seismic system with a trawl resistant housing and acoustic telemetry. This will be used for subsequent marine investigations of this sort.

The National Geoelectromagnetic Facility is also carrying out a large scale multidisciplinary investigation at Newberry volcano under Department of Energy support. We are collaborating with Zonge International Inc (Tucson) and the National Energy Technology Lab of the Department of Energy to image the migration of fluids deep beneath the flanks of Newberry caldera as the volcano undergoes a geothermal stimulation (pressurized well injection) by a geothermal development company. Our work involves 3D/4D magnetotelluric and controlled source electromagnetic investigations, ground based and satellite interferometric radar observations of dynamic ground surface deformations, absolute and relative gravity measurements, precision GPS monitoring and geochemical investigations during a "hydroshearing" episode, and during a controlled system depressurization. The goal is to develop technologies to allow geothermal operators to optimize the longevity and energy extraction from an enhanced geothermal system. The methods we are developing will be transferrable to other geothermal systems, and also to shale oil/gas hydrofracturing areas.

We have recently been awarded NSF funding to analyze EarthScope magnetotelluric data from the North American mid-continent region, in the vicininty of the mid-continent rift, and we have just received an additional year of funds to operate the EarthScope magnetotelluric program through the end of FY2013, a continuation of several million dollars in long-running NSF investment in OSU's EarthScope MT project. We are also part of the IRIS 5-year renewal proposal being considered by NSF for continuation of EarthScope operations through 2018. Thus far we have completed a regular grid of magnetotelluric stations, with 70 km spacing, spanning the NW quadrant of the US and another large footprint covering the north central US. Our eventual goal is complete a regular grid of MT stations spanning the entire continental US and Alaska.

In my spare time, I am carrying out a magnetotelluric survey in the Empty Quarter (Rub' al Khali) of Saudi Arabia under Saudi support. We are assisting King Saud University's efforts to locate groundwater resources in the region north of the Yemen and Oman borders. We've been working to develop special methods to obtain high quality electromagnetic data in the heart of the largest sand desert in the world. The arid conditions there make conventional methods of measuring electric fields using grounded electrolytic dipoles ineffective, so we are implementing methods of capacitively coupling to the desert sands.

The National Geoelectromagnetic Facility at OSU (, which was established using 2009 ARRA funding from NSF, currently operates 46 portable long-period magnetotelluric instruments and 7 permanently installed MT observatories. The NGF is completing acquisition of 26 additional next generation wideband/ultra-wideband electromagnetic instruments, in collaboraiton with Zonge International, and it serves as the US national academic instrument pool for electromagnetic geophysics. The lab also currently has two seafloor electromagnetic receiver systems. The NGF has two full time technical support staff and a team of graduate and undergraduate students including two through OSU's Increasing Diversity in the EarthSciences, and summer REU students from Loyola University and UCSD. We'd welcome inquiries from talented undergraduates at Brown who may be interested in an REU experience in the great Northwest, or from potential grad students and postdocs.

Class of 1980:

James Whitford-Stark, PhD writes: I fell and smashed my hip so got a titanium implant. It severely restricted my ability to do field work, so I retired early. Now having fun going places on vacation this year rather than work. So far, Dominican Republic and Cyprus. Bermuda and Texas coming up.

Class of 1981:

William Osborn, ScB writes: I am now representing the State of Texas in cases where its oil and gas reserves beneath state riverbeds are being drained by offsetting horizontal wells. We are having an oil boom here, with about 200 new horizontal well drilling permits being approved every week. The best advice I had at Brown was from Jan Tullis long ago, saying that if I was going to get a geology degree I should not mess around, but should go for the Sc. B., which I did. I was interested in the subject because of all the Cretaceous era fossils at our ranch, and one of her grad students kindly sawed and polished one for me, and I was hooked.

Our daughter graduated from Yale in May, but youngest son is now applying to colleges and I am trying to get him to apply to Brown. They accepted our daughter but she liked the residential college system at Yale so chose it instead, got a degree in Latin American studies and is now in Brazil working on preparation for 2016 Olympics in Rio de Janeiro.

Class of 1982:

David Grinspoon, AB: in April 2012, NASA and the Library of Congress announced the selection of David H. Grinspoon to be the first Baruch S. Blumberg NASA-Library of Congress Chair in Astrobiology.

Michael Ravine, ScB writes: I am project manager on the development of the four science cameras on the Curiosity rover. FOUR MALIN SPACE SCIENCE SYSTEMS (MSSS) CAMERAS ON THE CURIOSITY ROVER RETURN SPECTACULAR PICTURES FROM MARS

When the Curiosity rover of the Mars Science Laboratory Project (MSL) landed on Mars on 5 August 2012, on board were four cameras developed by Malin Space Science Systems (MSSS): the 34 mm and100 mm Mast Cameras (Mastcam), the Mars Hand Lens Imager (MAHLI), and the Mars Descent Imager (MARDI).

The Mastcams were designed to be the science imaging “workhorse” for the MSL rover. The cameras, capable of taking full color images analogous to those taken by consumer digital cameras, are mounted on the rover’s remote sensing mast, where they can be panned and tilted to provide image coverage around the rover, both near the rover and out to the horizon. The Mastcams are also capable of acquiring 720p high definition video at a rate of about 7 frames per second, as well as stereo (3D) images of the terrain explored by the MSL rover. The 34 mm Mastcam has shot a panorama of the Gale Crater landing site shortly after landing (Figure 1), as well as an image of another MSSS-built camera on the end of Curiosity’s robotic arm (Figure 2). The Mastcam 100 mm camera is a telephoto system, designed to capture detailed views from up to 10 miles away. Figure 3 is a Mastcam 100 mm image of the flanks of Mt. Shape, showing the layered structure thatCuriosity will be investigating in the coming year.

The cameras I helped build on the Curiosity rover are still working great. I just put together this self-portrait of the rover shot with our camera on the rover's robotic arm:

Almost like being there.

Class of 1984:

Michael Wysession, ScB: Michael Wysession class of 1984 (Washington University in St. Louis) got married in September to Margaret Farnon (Brown '84), on the beach in Delaware, just a short ways up the coast from where they went camping together 31 years ago. (Speedy, for a geologist.) Professionally, Michael and his team finished installing an IRIS PASSCAL seismic array in Madagascar this past August, and he has been busy supervising the writing of the Earth and Space Science standards for the national K-12 Next Generation Science Standards."Michael Wysession (Brown '84) and Margaret Farnon (Brown '84) were married on the coast of Delaware in September in a small family ceremony, not far from where they went camping as freshmen (32 years ago!). Michael (seismology professor at Washington University in St. Louis) now has his complete array of seismometers installed in Madagascar. Michael is also a lead author of the national K-12 Next Generation Science Standards, in charge of Earth and space science. The new standards, which are in the process of being adopted by most states in the country, will recommend a full year of Earth and space science in both middle school and high school, and that in both cases it be taught following the bulk of physical and life sciences."

Class of 1996:

Charles (Chuck) Magee, ScB is working for Australian Scientific Instruments, where he sets up SHRIMP mass spectrometers and trains geoscientists in their use. He recently discovered that these high resolution SIMS instruments can function as really expensive seismometers, when the surface waves from a Japanese earthquake wiggled an instrument he was turning up. While this career detour into instrumentation mans that Chuck hasn't seen a rock in the wild recently, he enjoys talking to geologists who do at major conferences. His daughter is in first grade at school, and his son is considering repeating the terrible twos.

Irene Antonenko, PhD: For over a year has been the science co-lead on CosmoQuest's Moon Mappers project ( CosmoQuest involves the general public in on-going science research through crowd-sourcing of labor-intensive, yet easily mastered tasks. The Moon Mappers component asks citizen scientists to identify and measure impact craters on the Moon using very high resolution images from NASA's Lunar Reconnaissance Orbiter Narrow Angle Camera. The data gathered by Moon Mappers volunteers is being used by Irene and co-lead Stuart Robbins to address fundamental issues in lunar science, such as whether saturation of craters occurs at the same rate on all lunar surfaces, how processes such as impact-induced seismic shaking affect the crater population, and the implications these have for modelling the ages of lunar surfaces. We are also studying the validity of citizen-science data by comparing it with statistics from crater counting experts. We welcome anyone who's interested to come count lunar craters with us.

Brown Bears and Roving on Mars

By Ralph E. Milliken
Assistant Professor (Ph.D. ’06)

It’s worth every penny. That was one of the many thoughts that went through my head a year ago in August 2012 when I saw the first images of Mt. Sharp returned from NASA’s $2.5 billion dollar Mars Science Laboratory (MSL) rover, known as Curiosity. The nerve wracking ride to the surface, dubbed the ‘seven minutes of terror’, utilized the new sky crane landing system that included a parachute, a rocket powered descent stage, and cables to lower the rover softly to the ground. Although it sounds crazy (and looks even crazier), physics and unparalleled engineering triumphed and the landing went without a hitch, as evidenced by the amazing descent video sent back by the rover. The first several months of rover operations required science team members to work at JPL, and in some ways it was like a reunion. There are a number of Brown graduates on the science and engineering teams, far too many to list here, and they are a part of the hundreds of people who continue to work tirelessly to ensure that Curiosity achieves its goals.

As for Curiosity’s field site, Gale Crater is a ~150 km diameter impact crater situated along the Martian dichotomy boundary that separates the ancient and heavily cratered southern highlands from the younger and smoother northern lowlands. A mountain, known colloquially as Mt. Sharp, rises more than five kilometers above the crater floor and appears to be composed of layer upon layer of sedimentary rock. Data from satellites orbiting Mars indicate that clay minerals, hydrated sulfates salts, iron oxides, and mafic minerals make up these layers, though their specific origins and the depositional environments they record await examination by Curiosity to be revealed. The evidence for a watery past, which includes hydrated minerals as well as fluvial features, is concentrated in the lower reaches of the mountain, whereas the younger overlying rocks lack fluvial features, hydrous minerals, and suggest a drier environment. These changes in lithology make Gale Crater and Mt. Sharp an interesting target for exploration because roving up the mountain is equivalent to roving through time, and the hope is that we can explore in detail how the Martian climate evolved during the time period in which the rocks were deposited.

One of the mission objectives is to characterize the geology and geochemistry of Mars and, by extension, to assess if any of the ancient environments preserved in the rock record at Gale could have been habitable. MSL is not a life detection mission, but identifying whether or not habitable environments ever existed on Mars is an important step in the greater search for Martian organics. However, we know from our geological experience on Earth that preservation of organic material is tricky business, and many post-depositional processes can erase the evidence of organics in what were once habitable environments, if organics were even there to begin with. Given these complexities, the hope is that Curiosity will encounter and be able to analyze a diversity of rock types that record equally diverse geological processes, thus increasing our changes of finding evidence of habitable environments. Fortunately, the rocks we have encountered so far in Gale are proving to be just as diverse and complex as those on Earth, and so far we have examined a variety of sedimentary rocks as well as some possible volcanic rocks. Indeed, the chemistry of the first rock that we touched with our analytical instruments, a piece of float whose source is unknown, turned out to be higher in alkalis than typical Martian basalts and is best classified as a mugearite (I’ll confess that I had to pull out my copy of Paul Hess’s petrology textbook for this one). More in line with the search for habitable environments, Curiosity has also encountered fluvial conglomerates, sandstones and, most recently, mudstones, all of which indicate aqueous activity.

Curiosity is the most capable and complex rover that has ever been sent to Mars, and the body of the rover houses the Sample Analysis at Mars (SAM) instrument suite that consists of a quadrupole mass spectrometer, a gas chromatograph, and a tunable laser spectrometer. These instruments allow for the detection of trace amounts of organics (if they happen to be present) and measurements of isotopic variations in soil, rock, and atmospheric samples. In addition, the CheMin X-ray diffraction instrument provides definitive mineralogical identification, a first for a Mars rover. The first sample passed to these instruments came from scooping a portion of a small drift of sand named Rocknest, and CheMin data showed it to be material of basaltic composition with tens of percent amorphous material. The latter may be the weathering product of the former under the cold, arid conditions that Mars has experienced for the past several billion years, and the results of this first time activity have provided detailed information about geological processes and water-rock interactions on ‘modern’ Mars.

Since the activities at Rocknest, Curiosity has traveled downsection (and away from Mt. Sharp) to a region known as Yellowknife Bay, one of the lowest points along the crater floor. The primary destination of the mission is still Mt. Sharp, but the diversion to this location and the associated costs in time were worth the wait. Simply put, the rocks in Yellowknife Bay are spectacular. The lower strata are fine-grained, relatively soft, and are best described as Martian mudstones. These rocks also exhibit concretions and other distinct diagenetic features, indicating a complex history of interaction with water, and they were an ideal location for the first time drilling activity. Earlier this year, Curiosity made history by drilling into a rock on Mars and analyzing the retrieved rock powder with its onboard analytical instruments. Even a casual glance in the night sky confirms that Mars is the red planet due to the abundance of iron oxide, but the science team was thrilled by the decidedly non-red color of the drill powder and rock. The CheMin instrument confirmed that these Martian mudstones contain abundant clay minerals, and they are crosscut by veins and fine fractures filled with calcium sulfate. These results, in combination with measurements by other instruments on the payload, have led to the conclusion that the rocks in Yellowknife Bay record evidence of a habitable environment, a huge step forward in our understanding of conditions on ancient Mars. However, there are still more questions than answers, and Curiosity has now departed Yellowknife Bay and begun her long trek to the base of Mt Sharp. The science team will continue to examine the vast amount of data that pour in, and with any luck we will be able to carefully and methodically piece together the history of Gale Crater as any field geologist would hope to do.

Being a part of the MSL mission is an unbelievable experience, and waking up each morning to view images and data from Mars as Curiosity roves the surface is inspiring, to say the least. Some current and future students in the geology program will also be able to participate in the mission, allowing the next generation of Brown graduates to experience firsthand the wonders of planetary exploration. No one on the team knows what will be around the next bend, behind the next rock, in the next rock, or what is really waiting for us at the base of Mt. Sharp. But if you hear about the exciting discoveries that Curiosity is sure to make over the coming months and years then be proud to know that those results are in part due to the efforts of a number of graduates from our very own geology department here at Brown.

Celebration of Jan Tullis

On June 15, 2013 alumni, faculty and staff came together to celebrate the profound contributions that Jan Tullis has made to undergraduate teaching and mentoring throughout her career. 

Jan has been an essential part of the Brown University Geological Sciences Department family since 1970. Her compassion, skill and dedication to her students, both current and former, is legendary.  Those students came out in force to honor Jan in a big way. The response to this celebration for Jan was extraordinary! More than 100 alumni, current students and colleagues came together from as far away as Myanmar (Fatma Khatib ’05) and Alaska (Tina Neal ’81) for the opportunity to re-connect with Jan and each other and to share updates on their lives and share memories of their time at Brown University.  Shauna Edson ’05, graciously offered her scrapbooking skills and created a beautiful Memory Book composed of recollections, stories, memories and photos sent to us by alumni over six months and which was presented to Jan at the dinner. It was a really lovely day and Jan was so touched by the enthusiastic response.

After a week of rain and chilly, dreary weather, June 15th dawned sunny and breezy; a perfect day for a field trip to Beavertail in Jamestown, RI. As those who’ve taken GE 22 know, field trips are an integral part of the course work! The motor coach arrived at 9:00 a.m. for at 9:30 a.m. departure. Boxed lunches were loaded into the bus, name- tags were passed out, and sunscreen was applied in preparation for the day. While the field trip included some real geology, its primary goal was to provide an opportunity to get together.  All attendees reported that it was a great time and the weather was fully cooperative!

The motor coach returned to the GeoChem building at 2:30 p.m. to give folks a chance to either rest up in preparation of the evening’s events or to catch up with Jan (she was out on MacMillan Green by the rocks). Undergrad concentrators Julia Carr and Rory MacFarlane volunteered to conduct tours of the Department for those interested and had the energy after all that walking!

The main event of the day was an informal reception and dinner, in Jan’s honor, held at the Faculty Club. A very generous anonymous donor requested to cover the cost of the reception and dinner, and in keeping with the donor’s wishes, we enjoyed a New England themed menu. Bill Collins created a really nice slide show of Jan through the years, which everyone enjoyed viewing. It was a packed house, with over 100 guests in attendance!

As the reception wound down, guests were invited into the dining room, where Chair Tim Herbert kicked off the evening with a toast to Jan, and Shauna Edson ’05 presented Jan with the Memory Book.

After guests enjoyed a delicious dinner, Karen Fischer and Greg Hirth opened the floor for testimonials to Jan. There was a steady stream of alums that stepped up to the microphone to fete Jan and to express the great impact she’s had on their lives. Some folks had their comments written beforehand, some spontaneously queued up to share a memory or story.  Many stories were funny and all were heartfelt.  Jan was extremely touched by the outpouring of affection.

The evening ended with people trading email addresses and phone numbers with promises to keep in touch and to stay in touch. It was a really wonderful testimonial to Jan and her profound influence on her many students through the years!

Finally, through everyone’s generosity, over $17,000 has been raised in the field fund to honor Jan, and until the end of August 2013, an anonymous graduate will match dollar for dollar any new contribution to the fund up to a total of $10,000. Please consider contributing to the fund. It’s a great way to benefit students and a great way to further recognize Jan.

Desert RATS

Graduate Students Debra Hurwitz and Mark Salvatore Participate in NASA Technology Development Study in NASA Houston Mission Control

Graduate students Debra Hurwitz (now a Postdoctoral Research Fellow at the Lunar and Planetary Institute in Houston) and Mark Salvatore (now a Postdoctoral Research Associate at Arizona State University) were invited to participate in the NASA-run Desert Research and Technology Studies (colloquially known as “Desert RATS”) at NASA’s Johnson Space Center in Houston, Texas, through Professor Jim Head’s long-standing participation in NASA Astronaut Training program.  Set up in the renowned Mission Control Center at Johnson Space Center, Hurwitz and Salvatore were two of 22 scientists tasked with planning and participating in geologic activities of astronaut crews at a field site north of Flagstaff, Arizona, where the majority of RATS activities occur.  The two were also responsible for providing geologic interpretations of the field site and for developing protocols to be used on future human exploration missions throughout the solar system.

NASA is committed to researching and developing methods, techniques, systems, and technology necessary to prepare for the future human exploration of space beyond low Earth orbit.  “The technologies and protocols being developed at Desert RATS are not for if NASA sends humans back to the Moon, on to Mars, or beyond, but when”, says Salvatore.  “Developing these systems now will ensure that the astronauts, engineers, scientists, and flight controllers will be ready to proceed with human exploration when the time comes.”  In pursuit of human exploration in space, NASA announced the design for the new Space Launch System that will be used to propel humans beyond lower Earth orbit on September 13, 2011, and NASA contractors began assembling the first space-faring Orion capsule that sat on top of the rocket on September 9, 2011.

This year’s Desert RATS activities were designed to test the capabilities of human exploration on an asteroid.  “It’s very different than working on the Moon or Mars”, says Hurwitz.  In particular, the astronauts will be challenged with working in extremely low gravity and with potentially crippling communications and mobility constraints.  “We worked with a 50-second one-way delay between Houston and the field to simulate data and communications restrictions, although 50-seconds is likely an underestimate of the actual delays that we would be facing.”  Hurwitz added that these delays prevented the field crews and Mission Control from engaging in conversational exchanges and put severe limitations on camera and GPS-tracking capabilities.

The teams only received one full day off during the two week operations test period and spent most of their free time interpreting images, generating hypotheses regarding the regional geology, and organizing sample and image data for use during future investigations.  The crew often worked more than 12-hours per day, but that didn’t stop them from enjoying their time working with fellow scientists and NASA astronauts.  “Working in Mission Control is as amazing as it sounds,” Salvatore added.  “We’re just honored to have been given the opportunity to help out.”

The Third Moscow Solar System Symposium

October 8-12, 2012 
Space Research Institute, Moscow, Russia

by Ken Ramsley

A science meeting that attempts to present topics that cover the entire solar system in plenary sessions from the points of view of the planetary sciences, space mission planners and national funding priorities is reminiscent of kabobs skewered, cooked and served steaming hot last Sunday at Moscow's Vernissage flea market.  At the Third Moscow Solar System Symposium meeting -- with more than 800 exoplanets discovered to date -- we were reminded of how many planets there might be in the Universe (perhaps as many as there are stars!), and from this perspective, several papers focused on planetary system formation as universal processes where own solar system is now more often viewed as a well-studied case rather than an archetype for what we might expect to find in other systems.

The Third Moscow Solar System Symposium, 2012The Third Moscow Solar System Symposium, 2012


Rather than equations, the Universe produces phenomena, an with the discovery of phenomena and its correlation to theory as a major goal, we were privileged to witness presentations on proposed spacecraft missions to the Moon, Venus, Mars and the icy moons of Jupiter, each at various stages of planning.  Russian Federation Roscosmos head, Vladimir Popovkin, emphasized mission plans in cooperation with the European Space Agency including the ExoMars orbiter/lander (where NASA had once been a partner), and also ambitious plans for two lunar landers, a Mars sample-return mission and a reconstituted attempt to return samples from Phobos after the deeply-felt failure of Phobos Grunt, which was lost last year (to be relaunched in ~2022).

In a poster session I presented my own research on Phobos which focuses on the proportions and distribution of martian impact ejecta that might be observed in the regolith of Phobos.  Research on this moon is largely driven by how we have answered so few of the big questions even after spacecraft data in hand going back 36 years.  We know the bulk density of Phobos (~1.86 g/cm3) and its shape (average radius ~11.08 km).  But we don't know where it was formed, how it was formed, why it orbits within the synchronous altitude of Mars, if it is desiccated or potentially a huge source of frozen water.  Planetary researchers often lament a lack of data, and in the case of Phobos, we are clearly lacking at least one key piece of the puzzle.  Adding to the mystery, Phobos is raked and cross-cut by hundreds of ancient grooves produced by unknown forces > ~3 Gyr ago, according to the presentation of Schmedemann et al.  Shi, Willner and Oberst presented a poster that maps surface gravitational forces where today some of the grooves trace gravitationally through uphill and downhill tracks, whereas when Phobos orbited at higher altitudes from Mars the uphill and downhill distributions were vastly different due to the slower orbital and tidally-locked rotational angular velocity.  In conversations with Dr. Oberst, I learned, to my relief, that the three-dimensional model of Phobos produced by Peter Thomas from NASA data two decades ago (and often at the center of my research on Phobos) has been refined more recently with only minor improvements in localized surface detail, and the Thomas model is still a valid shape for simulations of the interaction of Phobos with ejecta from Mars, debris trapped in orbits of Mars and other physical intersections.

Beyond the meeting, our five-day visit to Moscow included scheduling kabobs where we managed to squeeze in a visit to Red Square and to Gum (pronounced "goom"), one of the most opulent shopping places on the planet where common people are still welcome, that also predates shopping malls built in the USA by at least 50 years (if the "first mall in America" claim of the original Shopper's World in Framingham, MA is true).  We also visited the State Historical Museum adjacent to Red Square, which has endured two revolutions since its construction, and where the 20th Century housed on the third floor is not currently open for inspection.  On Tuesday evening of our visit we attended the Kremlin Theater ballet for a rousing performance of Sleeping Beauty, and the evening prior to our departure we enjoyed a newly opened musical which places a slight spin on the trials and travails of Catherine the Great, who was apparently far more inclined to hand out trials and travails than accept or tolerate those directed at her by others.
