Short summary
We studied late Quaternary permafrost at the Oyogos Yar coast (Dmitry Laptev Strait) to reconstruct palaeoclimate and palaeonvironmental conditions in the Northeast Siberian Arctic. Our ice-wedge stable isotope record, combined with data from Bol'shoy Lyakhovsky Island, indicates coldest winter temperatures during MIS5 and MIS2, warmest conditions during the Holocene, i.e. today, and non-stable winter climate during MIS3. New IRSL ages reveal high climate variability during MIS5.
