A corrected paleotemperature reconstruction of the Vostok Ice Core Data [Petit et al., 2001] as used in [Nicolsky et al., 2012] to model the temperature anomaly, Tv, in the Laptev Sea shelf. See equation (2) in Nicolsky et al. [2012] for further details. The correction is based on regional paleotemperature data in Kaplina and Kuznetsova [1975], Kaplina and Chekhovsky [1987], Balobaev [1991], and Konishchev [1998]. References: Balobaev, V.
