A seismic analysis of subglacial lake D2 (Subglacial Lake Cheongsuk) beneath David Glacier, Antarctica [PDF]

The Cryosphere
Subglacial 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

Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica [PDF]

The Cryosphere, 2020
Subglacial water plays an important role in ice sheet dynamics and stability. Subglacial lakes are often located at the onset of ice streams and have been hypothesised to enhance ice flow downstream by lubricating the ice–bed interface.

Improved monitoring of subglacial lake activity in Greenland [PDF]

The Cryosphere, 2022
Subglacial lakes form beneath ice sheets and ice caps if water is available and if bedrock and surface topography are able to retain the water. On a regional scale, the lakes modulate the timing and rate of freshwater flow through the subglacial system ...

Assessing the subglacial lake coverage of Antarctica [PDF]

Annals of Glaciology, 2016
Lakes beneath the Antarctic Ice Sheet are known to decrease traction at the ice base and therefore can have a great impact on ice dynamics. However, the total extent of Antarctic subglacial lakes is still unknown.

Physiological Ecology of Microorganisms in Subglacial Lake Whillans. [PDF]

Front Microbiol, 2016
Subglacial microbial habitats are widespread in glaciated regions of our planet. Some of these environments have been isolated from the atmosphere and from sunlight for many thousands of years. Consequently, ecosystem processes must rely on energy gained from the oxidation of inorganic substrates or detrital organic matter.

Development of a clean hot water drill to access Subglacial Lake CECs, West Antarctica

Annals of Glaciology, 2021
Recent drilling successes on Rutford Ice Stream in West Antarctica demonstrate the viability of hot water drilling subglacial access holes to depths >2000 m.

Drainage and refill of an Antarctic Peninsula subglacial lake reveal an active subglacial hydrological network [PDF]

The Cryosphere, 2022
The presence of subglacial lakes and subglacial hydrological networks under the East and West Antarctic ice sheets is now relatively well understood, whilst their influence on ice dynamics is the subject of ongoing research.

Geophysical constraints on the properties of a subglacial lake in northwest Greenland [PDF]

The Cryosphere, 2021
In this study, we report the results of an active-source seismology and ground-penetrating radar survey performed in northwestern Greenland at a site where the presence of a subglacial lake beneath the accumulation area has previously been proposed. Both
