Geologic Climate Research in Siberia
Meet the Team
Teacher - Tim Martin
Although he grew up in several locations around the country, Tim Martin has always felt most at home in the natural world. His persistent curiosity led to his undergraduate study of the natural sciences and art at Goshen College and recently he completed his M.S. in teaching geosciences through Mississippi State University. Whether using recent data for weather forecasting, seismograms for mapping plate tectonics, or making real-time observations with an Internet accessible radio telescope, Mr. Martin has a passion for bringing real time science into his Earth Science classroom at Greensboro Day School. In his free time, he may be found "up close and personal" with earth science while rock climbing with his family. Mr. Martin is excited to be a Polar TREC teacher as he sees Lake El'gygytgyn as an important crossroads for geology, climatology, and planetary science.

Researcher - Julie Brigham-Grette
Dr. Brigham-Grette is the US Chief Scientist of the Lake El'gygytgyn Drilling Project and also oversees studies of past sea ice history in the Bering Strait. She has recently been involved in the IPY STEM Polar Connections project to integrate the study of polar regions and International Polar Year activities into the middle and high school curriculum.
Where are They?
Lake El'gygytgyn (pronounced el'geegitgin) is located 100 km (62 miles) north of the Arctic Circle and 250 km (155 miles) inland from the Arctic Ocean (67.5° N and 172° E) on the remote Chukchi Peninsula in the Russian Far East. This large lake measures 12 km (7.5 miles) wide and roughly 170 m (558 feet) deep. It is positioned on the continental divide between the Arctic Ocean and the Bering Sea in the middle of Anadyr Mountains. The team will live and work out of a temporary camp located on the west shore of the frozen lake ice.
What are they Doing?
An international team of researchers from the United States, Germany, Russia, and Austria will be traveling to northeast Russia to conduct a large-scale scientific drilling project in Lake El'gygytgyn (pronounced el'geegitgin), a crater lake created 3.6 million years ago by the impact of a meteorite measuring about 18 km in diameter. The team will work on the lake ice throughout the winter, using a customized light-weight drill rig to obtain drill cores of layered muds from two sites in the lake.
Lake El'gygytgyn possesses a unique record of prehistoric climate change in the arctic. Because this basin was never glaciated, an uninterrupted sediment sequence of nearly 400 m (1312 feet) has accumulated at the bottom of the lake. Sediment cores collected during this expedition will be used to gather information about the history of the basin and compare it with similar paleoclimate records from other parts of the world, helping researchers to better understand the arctic's role in global climate change.
The team also plans to drill a short distance into the highly fractured rock layer below the sediments to learn more about meteorite impacts. Because of the particularly well-preserved rock structure in Lake El'gygytgyn, the team will be able to learn how igneous target rocks in this area respond to impacts, potentially providing the basis for important understanding related to cratering processes on Mars.
Geologists will use the data collected from the project to reconstruct past climate records on longer time scales, improve understanding of the climate system, and better inform scientists who predict future climate change.
