    ISOTOPIC REGIME OF SUBGLACIAL LAKE VOSTOK ON EVIDENCE FROM DEEP ICE CORE STUDIES by A. A. Ekaykin, V. Ya. Lipenkov, A. V. Kozachek

    Published 2015-11-01
    “…Meanwhile, in the nearest future this study will be developed by the completing of the measurements of the whole 5G-2 core (to the depth of3769 m), as well as the analysis of the short-term (1 cm) variations in the bottom part of the ice core, where the isotopic signal must be fully preserved without being erased by the molecular diffusion. Also, the measurement of the first lake water sample recovered from the drill after the penetration will allow the comparison with the lake ice isotope content in order to experimentally define the effective isotope fractionation coefficient and thus constrain the possible mechanism of the lake ice formation.…”
