Stable oxygen isotopes composition (δ¹⁸O), hydrogen (δ²H) and deuterium excess values in northwestern part of Kotelny Island, northeastern Russian Arctic

Stable isotopes were measured at the Isotope Laboratory of the Faculty of Geography of Moscow University. The analysis was performed on a Finnigan Delta-V Plus mass spectrometer with a standard gas-bench option and the results were calibrated against international (V-SMOW and SLAP) and laboratory standards, with internal 1σ errors of ±0.6 ‰ for δ2Н and ±0.1 ‰ for δ¹⁸O.
