IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The identification and activity monitoring of Antarctic subglacial lakes contribute to the analysis of the mass balance and sea level change. Remote sensing techniques, especially satellite altimetry, are ideal ways for identifying active subglacial ...

Advances in modelling subglacial lakes and their interaction with the Antarctic ice sheet [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2016 Subglacial lakes have long been considered hydraulically isolated water bodies underneath ice sheets. This view changed radically with the advent of repeat-pass satellite altimetry and the discovery of multiple lake discharges and water infill ...

Clean access, measurement, and sampling of Ellsworth Subglacial Lake: A method for exploring deep Antarctic subglacial lake environments [PDF]
Reviews of Geophysics, 2012 Antarctic subglacial lakes are thought to be extreme habitats for microbial life and may contain important records of ice sheet history and climate change within their lake floor sediments. To find whether or not this is true, and to answer the science questions that would follow, direct measurement and sampling of these environments are required. Ever

Greenland subglacial lakes detected by radar [PDF]
Geophysical Research Letters, 2013 AbstractSubglacial lakes are an established and important component of the basal hydrological system of the Antarctic ice sheets, but none have been reported from Greenland. Here we present airborne radio echo sounder (RES) measurements that provide the first clear evidence for the existence of subglacial lakes in Greenland.

Subglacial lakes and jökulhlaups in Iceland
Global and Planetary Change, 2003 Active volcanoes and hydrothermal systems underlie ice caps in Iceland. Glacier-volcano interactions produce meltwater that either drains toward the glacier margin or accumulates in subglacial lakes. Accumulated meltwater drains periodically in jokulhlaups from the subglacial lakes and occasionally during volcanic eruptions.

Subglacial lake activity beneath the ablation zone of the Greenland Ice Sheet [PDF]
The Cryosphere, 2023 Hydrologically active subglacial lakes can drain large volumes of water and sediment along subglacial pathways, affecting the motion and mass balance of ice masses and impacting downstream sediment dynamics.

AN AUTOMATIC EXTRACTION METHOD FOR ANTARCTIC SUBGLACIAL LAKE BASED ON RADIO ECHO SOUNDING DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Detection of subglacial lakes and interpretation their hydrological connectivity is of great importance to understanding the mass balance of Antarctic ice sheet.
