Data sets

Gravimetric ice content of sediment samples and stable isotope characteristics for ice wedges and for pore and segregrated ice at the Oyogos Yar coast, Northeast Siberian Arctic Thomas Opel, Sebastian Wetterich, Hanno Meyer, Alexander Y.

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.
