from the first analyses of the longest sediment cores ever retrieved on land.

They were obtained from beneath remote, ice-covered Lake El'gygytgyn (pronounced El'gee-git-gin) ("Lake E") in the northeastern Russian Arctic. The lake is of interest to scientists because it has never been covered by glaciers.

That has allowed the uninterrupted build-up of sediment at the bottom of the lake, recording hitherto undiscovered information on climate change. Cores from Lake E go far back in time, almost 30 times farther than Greenland ice cores covering the past 110,000 years. The sediment cores from Lake El'gygytgyn reflect the climate and environmental history of the Arctic with great sensitivity.    Less «
