Arctic Impacts

Overview

Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater

Approximate Proxies

Overview

The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of

Salty or Not: A Taste of the Bering Sea

What happens to the salinity in the Bering Sea during ice and no ice conditions? Does it change throughout the year and at different depths during different seasons? Create a model of the Bering Sea in ice conditions. Change the conditions based on seasonal changes to explore the effects of runoff on salinity.
