Stable oxygen isotopes composition (δ¹⁸O), hydrogen (δ²H) and deuterium excess values in ice wedges and segregated ices in the Chara Basin, northern Transbaikalia, Russia

Stable oxygen isotopes composition (δ¹⁸O), hydrogen (δ²H) and deuterium excess values (dexc) in ice wedges and segregated (segr.) ice in the 6–8 m Chara River terrace and in the saddle of Udokan ridge near Uschelisty creek. Sampling was done in 2006–2009.Isotope analyses were done in the isotope laboratory of the Institute for Polar and Marine Research Alfred Wegener, Potsdam (Germany) using mass-spectrometer Finnigan MAT Delta-S (Dr. H. Meyer). Measurement errors of hydrogen and oxygen are 0.8‰ and 0.10‰, respectively from Meyer et al. (2000, doi:10.1080/10256010008032939).
