Isotope-geochemical composition of ice wedges in the slope yedoma on the Kular Ridge and reconstruction of the mean January air paleotemperature during 47,000-25,000 BP

The isotope composition and hydrochemical properties of the Late Pleistocene ice wedges in the outcrop of flat side of Kular Ridge located in the western part of Yana-Indigirka Lowland have been analyzed. It has been established that variations of the δ¹⁸О values in the ice wedges (varying -32.6 ‰ to -31.0 ‰) do not exceed 1.6 ‰. The mean winter and mean January temperature reconstructions have been carried out by means of the palaeogeocryologyical studies of the oxygen stable isotopes contained in ice wedges. In the Kular Ridge area, the mean January air temperature in Late Pleistocene was by 7 °C lower than the current. Besides, the lowest mean winter temperature was referred to the 37-32 ka BP.

Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.
