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
Beacon Valley is recognized by scientists as one of the most Mars-like environments on Earth. This lesson plan was created so that students could have the opportunity to examine the same landforms that scientists use to study the processes that operate in both of these extreme environments. There are two parts to this lesson. Teachers may choose to
The Dry Valleys region in Antarctica is known as the coldest, windiest, driest place on Earth. Beacon Valley is famous for its katabatic winds which can routinely knock fit adults and PolarTREC teachers to the ground. This lesson was created by PolarTREC teacher Jacquelyn Hams who experienced the cold and the full force of the winds in 2008

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.
