The oxygen isotope composition, radiocarbon age, hydrochemical characteristics of the Late Pleistocene ice wedges from Zelyony Mys Yedoma and air January paleotemperature reconstruction

The oxygen isotope composition of ice wedges, radiocarbon age, and hydrochemical characteristics have been studied in the outcrop of the Zelyony Mys Yedoma located on the right bank of the Lower Kolyma River. The mean January air temperature of the Late Pleistocene (48–15 cal ka BP) has been calcula...

Description
Summary:The oxygen isotope composition of ice wedges, radiocarbon age, and hydrochemical characteristics have been studied in the outcrop of the Zelyony Mys Yedoma located on the right bank of the Lower Kolyma River. The mean January air temperature of the Late Pleistocene (48–15 cal ka BP) has been calculated for certain periods for the key sections in the lower reaches of the Kolyma River. The reconstruction was based on a comparison of the isotopic composition of veinlets and the modern mean January air temperature for the period of ice wedge formation.
