Abstract: Taken at the flood A hidden subglacial world consisting of more than 140 lakes lies beneath the Antarctic ice sheet. It is widely assumed that these lakes are a static ecosystem, cut off from each other and the rest of the world. Far from it, according to a 16-month study of surface elevation changes in the region. Changes indicating a rapid discharge of water from one lake to another were detected, and it is possible that the entire subglacial drainage basin is flushed through periodically by massive water transfers.
