Lake Vostok behaves like a captured lake and may be near to creating an Antarctic jökulhlaup

Description :
This paper presents the first test of the captured ice shelf (CIS) hypothesis using field data from a modern ice sheet, by comparing the predicted geometry with that of Lake Vostok, the planet's largest existing sub-glacial lake, situated under the East Antarctic ice sheet. It is showed that Lake Vostok agrees with this hypothesis. The result also implies that the lake may well be of pre-glacial origin, and that it may have experienced jökulhlaups during previous interglacials.
