Determining Ice-Sheet Uplift Surrounding Subglacial Lakes with a Viscous Plate Model
Frontiers in Earth Science, 2017 We develop a viscous model of plate bending suitable for studying ice-sheet flexure due to subglacial lake filling and draining, and apply this model to determine the area of ice-sheet uplift surrounding a subglacial lake.

Basal melting over Subglacial Lake Ellsworth and its catchment: insights from englacial layering
Annals of Glaciology, 2020 Deep-water ‘stable’ subglacial lakes likely contain microbial life adapted in isolation to extreme environmental conditions. How water is supplied into a subglacial lake, and how water outflows, is important for understanding these conditions. Isochronal

Distribution and dynamics of Greenland subglacial lakes [PDF]
Nature Communications, 2019 AbstractFew subglacial lakes have been identified beneath the Greenland Ice Sheet (GrIS) despite extensive documentation in Antarctica, where periodic release of water can impact ice flow. Here we present an ice-sheet-wide survey of Greenland subglacial lakes, identifying 54 candidates from airborne radio-echo sounding, and 2 lakes from ice-surface ...

Subglacial discharge weakens the stability of the Ross Ice Shelf around the grounding line
Polar Research, 2021 In this paper, we examine potential impact of discharge in Subglacial Lake Engelhardt, West Antarctica, on the stability of the Ross Ice Shelf around the grounding line by combining satellite altimetry and remote sensing images.

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.

Exploring subglacial Antarctic lake environments [PDF]
Eos, Transactions American Geophysical Union, 2005 While subglacial lakes have been suspected, and speculated about, for more than 50 years, recent analyses of historical and new data have shown that liquid water environments are common beneath the vast Antarctic Ice Sheet. Airborne radar surveys have now documented more than 145 subglacial lakes, the largest being Lake Vostok located 4 km beneath the ...

Recoverable autonomous sonde for subglacial lake exploration: electronic control system design
Annals of Glaciology, 2021 Subglacial lake exploration is of great interest to the science community. RECoverable Autonomous Sonde (RECAS) provides an exploration tool to measure and sample subglacial lake environments while the subglacial lake remains isolated from the glacier ...

Glaciohydraulic seismic tremors on an Alpine glacier [PDF]
The Cryosphere, 2020 Hydraulic processes impact viscous and brittle ice deformation. Water-driven fracturing as well as turbulent water flow within and beneath glaciers radiate seismic waves which provide insights into otherwise hard-to-access englacial and subglacial ...

Radar sounding survey over Devon Ice Cap indicates the potential for a diverse hypersaline subglacial hydrological environment [PDF]
The Cryosphere, 2022 Prior geophysical surveys provided evidence for a hypersaline subglacial lake complex beneath the center of Devon Ice Cap, Canadian Arctic; however, the full extent and characteristics of the hydrological system remained unknown due to limited data ...

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
