Contents of stable isotopes of oxygen (δ¹⁸O), deuterium (δ²Н) and deuterium excess values (dexc) of the Late Pleistocene massive ice exposed in the northern part of the Lake Hanikosito, Bovanenkovskoye oiL and gas condensate field.The ice isotopic composition was determined at the Laboratory of Stable Isotope Geochemistry (Lomonosov Moscow State University) using a Delta-V mass spectrometer with a standard gas bench option. δ¹⁸O measurement implied equilibration of analyzed samples with CO₂ over 24 h, while the δ²H measurement was carried out using a platinum catalytic agent over 40 min. The values are presented in δ‐notation in per miL (‰) relative to the Vienna Standard Mean Ocean Water (VSMOW). For measurements international standards V-SMOW, SLAP and MSU own Laboratory standard (snow of the Garabashi glacier) were used. Analytical precision was ±0.1‰ for δ¹⁸О and ±0.6‰ for δ²H.
