Who discovered the Lake Vostok?
Лëд и снег, 2016 A history of the subglacial lake Vostok that had been revealed near this Soviet Antarctic Station is briefly described in the paper. Three participants of the Soviet Antarctic Expeditions played a significant part in the history of the Lake discovery ...

Hydraulic impacts of glacier advance over a sediment bed [PDF]
, 2006 A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

Advances in modelling subglacial lakes and their interaction with the Antarctic ice sheet [PDF]
, 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 ...

A seismic analysis of subglacial lake D2 (Subglacial Lake Cheongsuk) beneath David Glacier, Antarctica [PDF]
The CryosphereSubglacial lakes beneath Antarctic glaciers are pivotal in advancing our understanding of cryosphere dynamics, basal hydrology, and microbial ecosystems. We investigate the internal structure and physical properties of Subglacial Lake D2 (SLD2), which is

Deep Clustering in Radar Subglacial Reflector Reveals New Subglacial Lakes
, 2023 Abstract. Ice-penetrating radar (IPR) imaging is a valuable tool for observing the internal structure and bottom of ice sheets. Subglacial water bodies, also known as subglacial lakes, generally appear as distinct, bright, flat, and continuous reflections in IPR images.

Analysis of long-term dynamic changes of subglacial lakes in the Recovery Ice Stream, Antarctica [PDF]
The CryosphereThe dynamic activity of subglacial lakes plays a crucial role in modulating glacial processes and the mass balance of the Antarctic ice sheet. The Recovery Ice Stream (RIS), projected to experience significant mass loss in East Antarctica during coming ...

Discovery of relict subglacial lakes and their geometry and mechanism of drainage
Nature Communications, 2016 Our understanding of subglacial lake drainage events is limited by a lack of direct observations. Here, the authors use ground penetrating radar to identify a relict subglacial lake and infer drainage mechanisms based on geomorphological features.

Journal of Glaciology, 2017 Discharge and water temperature measurements in the Skaftá river and measurements of the lowering of the ice over the subglacial lake at the western Skaftá cauldron, Vatnajökull, Iceland, were made during a rapidly rising glacial outburst flood ...

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.
