"I thought if I am a professional – an adult – and I was unaware of how unique and diverse the Arctic region is, my students must have the same misconceptions." - Chantelle Rose
Article about PolarTREC teacher Chantelle Rose's icebreaker-based expedition to collect some of the first winter information on the biology, chemistry, and physical oceanography of the Bering, Chukchi, and Beaufort Seas.
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
