Palaeo-ecological proxy data from Yedoma permafrost deposits on Sobo-Sise Island (Eastern Lena Delta, NE Siberia)

The dataset compiles data of fossil pollen, chironomid and diatom findings from late Pleistocene Ice Complex permafrost and its Holocene cover exposed at a Yedoma cliff on the northern shore of Sobo-Sise Island (Sardakhskaya Channel, eastern Lena Delta, NE Siberia). The chronology of the permafrost sequence is based on Wetterich et al. (2020).
