Comment:
Stable oxygen and hydrogen compositions in ice were analyzed in the stable isotope laboratory of the Faculty of Geography at Lomonosov Moscow State University using a Finnigan Delta-V Plus mass spectrometer applying equilibration techniques. The values are presented in δ-notation in per mille (‰) relative to the Vienna Standard Mean Ocean Water (VSMOW). International reference materials (V-SMOW-2, GISP, and SLAP) were used for the calibration. The analytical precision is ±0.1‰ for δ18О and ±0.8‰ for δ2H. Deuterium excess (dexc) was calculated as dexc = δ2H - 8δ18O (Dansgaard 1964). Totally, 84 samples of massive ice were analyzed for stable isotope composition, and organic micro-inclusions for 14C AMS analysis were extracted from 5 samples.
