Isotopic composition of hydrogen (δD), oxygen (δ¹⁸О) and Deuterium excess in veinlets of the syngenetic ice wedges in the Russian permafrost zone

DOI

The authors obtained new results on isotope data for recent growing ice wedges on the coast of the Chukotka Peninsula and summarized data from publications of the last 15-20 years. Field sampling was carried out in ice veinlets, usually lying under the grooves of interpolygonal ice wedge massifs. Identified variations of stable isotopes and values of deuterium excess in recent growing ice wedges, with age of about 100 years, penetrating into growing ice wedges at Russian permafrost zone, allow to consider the additional cryogenic fractionation during ice veinlets growth in frost cracks. The study confirmed the predominantly atmospheric origin of moisture, filling frost cracks. Limited cryogenic fractionation usually accompanies the freezing of melted snow after it fills the frost crack.

Hydrogen isotope ratios were analyzed in the stable isotope laboratory of the Geography Faculty of Lomonosov Moscow State University (Prof. Y.Vasil'chuk and Dr N. Budantseva) using a Finnigan Delta-V Plus mass spectrometer applying equilibration techniques. International water standards (VSMOW, SLAP) and MSU own laboratory standard - snow of the Garabashi glacierwere, were used for calibration. Analytical precision was ±0.8‰.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.The research was financially supported by the Russian Scientific Foundation (grant № 19-17-00126, Verification and validation of Late Pleistocene paleotemperature scenario based on the stable isotope data in syngenetic ice wedges in Siberia using independent paleoclimatic models) and Russian Foundation for Basic Research (grant № 18-05-60272, stable isotope study and calculations).
