This article and associated video describe the findings of researchers who undertook core drilling at Lake El’gygytgyn, a lake that sits today inside a basin formed by a meteorite that struck the earth 3.6 million years ago. An associated video allows us to hear the enthusiasm and details as researcher Julie Brigham-Grette describes the findings of this remarkable discovery.
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
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
Students will review charts of day length to determine when the sun will set at Toolik Lake.
Objective
Students will learn the following:
* The sun is the major source of energy for phenomena on the earth's surface, such as growth of plants, winds, ocean currents, and the water cycle.
* Seasons result from variations in the

PolarTREC Teacher, Tim Martin facilitated an unique learning opportunity when his students corresponded with him remotely in a Live from IPY! event. Local reporters covered the live event at Mr. Martin's school in Greensboro, North Carolina.
This article in the Polar Field Services "Field Notes" newsletter explains some of the fascinating science taking place in the spring of 2009 in northeastern Russia. It also highlights the logistical challenges with living and working in remote Russia.

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.
