The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
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.
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
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.
