δ¹⁸О values and winter air temperatures from the Ambarchik creek and Pokhodsk in the north to the Omolon River mouth and Kolymsky village in the south of the region are represented. Similar publications containing the δ¹⁸О data of the lower Kolyma area are used. ... : Oxygen isotope ratios were analyzed in the laboratory of Isotope Geology of the Institute of Geology of the Academy of Sciences of Estonia and in the laboratory of Isotope Hydrology of the Institute of Water Problems of the Russian Academy of Sciences of the USSR Academy of Sciences with the assistance of A.D. Esikov on the G-50 device. Control comparisons of the standards of both laboratories were carried out.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.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, isotope analysis) and the Russian Foundation for Basic Research (Award nr. 18-05-60272, data synthesis; 17-05-00793, analysis of meteorological data). ...
