Аннотация:The features of the Late Pleistocene ice wedges in the outcrop of the Zelyony Mys Yedoma located on the right bank of the Lower Kolyma River are considered. The oxygen isotope composition of ice wedges, radiocarbon age, and hydrochemical characteristics have been studied. Stable oxygen isotopes provide the main basis for reconstructing the mean January air temperature history of a site from ice wedges. Detailed quantitative assessments of paleogeocryological and paleoclimatic changes of the region in the Late Pleistocene 48–15 cal ka BP were performed.
