δ¹⁸O values from ice-wedge ice from Duvanny Yar collected in 1985

δ¹⁸O values from ice-wedge ice in 1985, collected in the sampling programme by Yu. Vasil'chuk, in Duvanny Yar (Vasil'chuk, 1992).In 1985, the top of the Duvanny Yar section was at 48 ma.s.l., the bottom at 6 m a.s.l.Oxygen isotope ratios (δ¹⁸O) in ice wedges (sampled in 1985) were measured in the Isotope Laboratory of the Tallinn Geological Institute (Prof. R.Vaykmae).
