Rapid discharge connects Antarctic subglacial lakes

Nature, 2006
The existence of many subglacial lakes provides clear evidence for the widespread presence of water beneath the East Antarctic ice sheet, but the hydrology beneath this ice mass is poorly understood. Such knowledge is critical to understanding ice flow, basal water transfer to the ice margin, glacial landform development and subglacial lake habitats ...

Antarctic subglacial lakes

Earth-Science Reviews, 2000
Abstract Antarctic subglacial lakes were first identified by Robin et al. (1970) after airborne radio-echo sounding (RES) investigations of the ice-sheet interior. Recently, satellite altimetry was used to measure anomalous near-flat regions on the ice-sheet surface that represent a manifestation of the subglacial lake beneath.

Cascades of subglacial lakes in Antarctica

Doklady Earth Sciences, 2012
Progress in understanding cascades of subglacial lakes in Antarctica and in the dynamics of their surface was derived using satellite laser altimetry measurements ICESat. The morphological and dynamical signs indicate subglacial lakes and the positions of their shore lines. Oscillations of surfaces in transition zones are periodic, while the changes in
