Brief communication: Subglacial lake drainage beneath Isunguata Sermia, West Greenland: geomorphic and ice dynamic effects [PDF]
The Cryosphere, 2019 We report three active subglacial lakes within 2 km of the lateral margin of Isunguata Sermia, West Greenland, identified by differencing time-stamped ArcticDEM strips.

Modeling Antarctic subglacial lake filling and drainage cycles [PDF]
The Cryosphere, 2016 The growth and drainage of active subglacial lakes in Antarctica has previously been inferred from analysis of ice surface altimetry data. We use a subglacial hydrology model applied to a synthetic Antarctic ice stream to examine internal controls on the

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 ...

Drainage networks, lakes and water fluxes beneath the Antarctic ice sheet
Annals of Glaciology, 2016 Antarctica Bedmap2 datasets are used to calculate subglacial hydraulic potential and the area, depth and volume of hydraulic potential sinks. There are over 32 000 contiguous sinks, which can be thought of as predicted lakes.

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

Journal of Quaternary Science, EarlyView.ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.
