Where is Lake El’gygytgyn?
Lake El’gygytgyn, formed by an astroid impact about 3.6 million years ago, gives scientists climate change clues via an extracted sediment core.
Among the many challenges facing the scientific community is determining why and how the Arctic climate system evolved from a warm forested ecosystem into a cold permafrost ecosystem. The Arctic region suffered this climate change sometime between 2 million and 3 million years ago during the mid-to-late Pliocene.
Now scientists are unlocking clues from the rocks of Lake El’Gygytgyn, a site where 3.6 million years ago an asteroid impacted the earth. The continuous depositional record scientists are studying from the site of the lake will provide, for the first time, an Arctic terrestrial perspective, reflecting new information of the mechanisms and dynamics of glacial-interglacial and millennial-scale change in the high-latitude region.
