Abstract

Subglacial lakes revealed Water has been found to gather in lakes underneath the Antarctic ice sheet, and it can move between lakes and drain catastrophically. Despite this, relatively little is known about how subglacial lakes influence ice sheet dynamics. Now satellite imagery has identified four subglacial lakes, similar in total area to Lake Vostok, right at the onset of the Recovery Glacier ice stream in East Antarctica. This suggests that subglacial lakes may initiate and maintain rapid ice flow, a mechanism that will need to be considered in future ice sheet mass balance assessments.
