Distribution and dynamics of Greenland subglacial lakes [PDF]
Nature Communications, 2019 Subglacial lakes can influence basal hydrology and ice flow in Antarctica, but are poorly constrained in Greenland. Here the authors provide the first ice sheet-wide inventory of subglacial lakes beneath GrIS, including 54 uncharted lakes.

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.

Estimating effective pressures in active subglacial lakes with ICESat-2 satellite altimetry [PDF]
Journal of GlaciologyThe difference between the ice and water pressures, or the effective pressure, influences water flow and sliding at the ice-bed interface. Effective pressure is typically quantified with subglacial hydrology models because direct measurements of the ...

Detection of 85 new active subglacial lakes in Antarctica from a decade of CryoSat-2 data [PDF]
Nature CommunicationsSubglacial lake activity influences ice sheet flow, grounding line discharge and ice shelf basal melting. Although 146 active subglacial lakes have been detected in Antarctica via ice surface elevation change associated with their activity, only 36 fill ...

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.

Detecting and Searching for subglacial lakes through airborne radio-echo sounding in Princess Elizabeth Land (PEL), Antarctica [PDF]
E3S Web of Conferences, 2020 Over 400 subglacial lakes were discovered in Antarctica through radio-echo sounding (RES) method and remote sensing. Subglacial lakes have significance in lubricating ice-bedrock interface and enhancing ice flow.

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]
The Cryosphere, 2013 We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

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.
