GEOL 0240 Class Trip

Students in GEOL 0240 taking sediment cores:

Undergrads in Geol-0240 after taking sediment cores in Succotash Marsh (southern RI). The cores will be taken back to Brown and examined for evidence of prehistoric and historic hurricane strikes in southern Rhode Island over the past 1000 years.

Seafloor Holds 15 Million Years of Monsoon History

Buildling a record of climate change on a geological time scale:

Clues about rainfall in the distant past — from river mud to tiny seashells — come to rest on the ocean floor. Sampling layers of sediment from the Indian Ocean will help researchers build an accurate picture of Indian monsoon activity going back 15 million years or more. Read about research conducted by Steve Clemens on a 2 month cruise on the JOIDES Resolution.

Gully patterns document Martian climate cycles

Martian gullies, old and new:

Gullies carved into impact craters on Mars provide a window into climate change on the Red Planet. A new analysis suggests Mars has undergone several ice ages in the last several million years. The driver of these climate swings is likely the Red Planet's wobbly axis tilt. Read the study, in press in the journal Icarus, by lead author Jay Dickson.

Reconstructing the African Humid Period

Dry Lakes?  :

A dramatic increase in rainfall at the end of the last ice age marked the beginning of the African Humid Period. Researchers using complex modeling systems have figured out the forces that drove that transition, including an important role for greenhouse gasses. Prof. Jim Russell was a co-author of a study published in Science. He discussed his findings and their implications with Kevin Stacey.

Symposium for Peter Schultz

Last weekend, about 100 undergraduate and graduate alumni gathered to celebrate the retirement of Professor Peter Schultz (Dept. of Earth, Environmental, and Planetary Sciences) at the historical Hope Club.

24 symposium speakers, including Brown alumni (now professors) from Japan and Alaska, presented their latest science research and connected their career trajectories to their experiences here at Brown, highlighting Prof. Schultz's influence on their lives.
