Stable water isotope composition and radiocarbon dates of permafrost ice wedges from Bol'shoy Lyakhovsly Island (New Siberian Archipelago)
Seven profiles of permafrost ground ice (i.e. ice wedges) were sampled in 1999, 2007 and 2014 either by chainsaw or by ice screw at coastal bluffs east and west of the Zimov'e River mouth (73.33°N, 141.35°E) at the southern coast of Bol'shoy Lyakhovsky Island (New Siberian Archipelago) in...
