Isotope studies of sediment-rich basal ice of Vavilov Glacier, Severnaya Zemlya

Pleistocene ice at the bottom of the Vavilov ice cap, Severnaya Zemlya, Russian Arctic

The Vavilov ice cap was perforated in 1988 by a drilling which reached the underlying frozen sediments. In contrast to the overlying glacier ice, the basal ice is composed of different ice layers with a variable debris load. The stable-isotope composition of these layers shows δ values much lower than everywhere else in the core or in the Vavilov ice cap. This is most probably the signature of a remnant of Pleistocene ice which, for the first time, is shown to occur in the Russian Arctic.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
