Comment:
δ¹⁸O in ice wedges of yedoma deposits in Chukchi Peninsula and Late Pleistocene paleotemperatures, 38–12 Kyr BP.Winter mean (twint.mean) and January (tJ) air temperature means for the Southern Chukchi Peninsula were inferred by comparing the oxygen isotope composition of present growing ice wedges (δ18Opiw) and winter temperatures for the period of their growth, were calculated using equation: tJ = 1.5 δ18Opiw (±3 °C), twint.mean = δ18Opiw (±2 °C). Mean annual ground temperatures were calculated using reconstructions of mean summer temperature by the technique of A. Vasil'chuk (2007) and of mean winter temperature by the technique of Yu. Vasil'chuk (1989).
