δ18O values for samples of recent syngenetic ice wedges and temperature parameters for Yamal Peninsula and adjacent regions and Russian Arctic Islands (from Vasil'chuk & Kotlyakov 2000 with additions).The oxygen stable isotope analysis was carried out in the Stable Isotope Laboratory of the Geography Department at Lomonosov Moscow State University, using a Delta-V mass spectrometer equipped with a standard gas bench. Oxygen isotope ratio was determined using equilibration techniques: samples for δ18О analysis were equilibrated with СО2 for 24 hours. For the measurements, international standards V-SMOW and international laboratory standards of the IAEA, as well as of the isotope laboratory of the Austrian Institute of Technology, were used. The precision of the measurements is 0.1‰. ...
