δ¹⁸O, δ²H and deuterium excess values in snow from a snow patch in Vorkuta town

δ¹⁸O, δ²H and deuterium excess (dexc) values in snow from a snow patch in Vorkuta town (sampled December, 2018) and in the fresh snow (sampled December, 2005) during a single snowfall along a 300 km SW–NE transect (from 66.05 N, 60.366667 E to 67.05 N 65.333333 E).Hydrogen and oxygen isotope ratios (δ¹⁸O and δ²H) in ice and snow (sampled in 2003 and 2004) were measured in the Isotope Laboratory of the Vienna Arsenal Center (Prof. D. Rank, Dr W. Papesch and M. Körner). Analytical precision was ±0.1‰ for δ¹⁸O and ±1‰ for δ²H. Stable isotope ratios in ice and snow sampled in 2018 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 (SMOW, GRESP and SLAP) were used for calibration. Analytical precision was ±0.4‰ for δ¹⁸O and ±1‰ for δ2H.
