Abstract

Samples of ice from a short core drilled at the Vostok station were analysed for ³He and ⁴He. The samples were taken from below the firn-ice transition region (which lies 90-100 m below the surface). Results suggest that between 27 and 42% of the initial helium had escaped before the ice samples were incorporated into the copper sample tubes. The different causes of bias, principally linked to the high diffusivity of He in ice, are reviewed and discussed. There is an abridged English version. -from English summary
