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

ICDP Lake El'gygytgyn Drilling Project Blog

Lake El'gygytgyn (also called, Lake E) permafrost drilling started in mid-November of 2008. The ICDP (International Continental Drilling Program) is posting news reports and images to this blog several times each week. Check out early reports from Lake E.
