High-Resolution Oxygen Isotope and Deuterium Diagrams for Ice Wedges of the Batagai Yedoma, Northern Central Yakutia

详细

The stable oxygen and hydrogen isotope composition of Late Pleistocene syngenetic ice wedges of Batagai yedoma are studied, and detailed isotope diagrams are obtained. The reconstructed mean January paleotemperature is lower than –51°С, which completely confirms the validity of the paleotemperature maps made earlier for the period of 30–25 ka BP where the location of the Batagai section within the isotherm of –48°C.
