Overview and significance of a 250 ka paleoclimate record from El’gygytgyn Crater Lake, NE Russia

Sediment piston cores from Lake El’gygytgyn (67 N, 172 E), a 3.6 million year old meteorite impact crater in northeastern Siberia, have been analyzed to extract a multi-proxy millennial-scale climate record extending to nearly 250 ka, with distinct fluctuations in sedimentological, physical, biochemical, and paleoecological parameters. Five major themes emerge from this research. First the pilo...
