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

open access: yesThe 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

Basal melting over Subglacial Lake Ellsworth and its catchment: insights from englacial layering

open access: yesAnnals 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

Determining Ice-Sheet Uplift Surrounding Subglacial Lakes with a Viscous Plate Model

open access: yesFrontiers 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.

Subglacial discharge weakens the stability of the Ross Ice Shelf around the grounding line

open access: yesPolar 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]

open access: yesE3S 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.

Physical and Chemical Controls on Habitats for Life in the Deep Subsurface Beneath Continents and Ice [PDF]

open access: yes, 2016
S.M. was funded by an STFC Aurora studentship (grant ST/1506102/1) and the NASA Astrobiology Institute Program on Foundations of Complex Life, Evolution, Preservation and Detection on Earth and Beyond (grant NNA13AA90A). J.P.

A revised inventory of Antarctic subglacial lakes [PDF]

open access: yes, 2005
The locations and details of 145 Antarctic subglacial lakes are presented. The inventory is based on a former catalogue of lake-type features, which has been subsequently reanalysed, and on the results from three additional datasets.

Recoverable autonomous sonde for subglacial lake exploration: electronic control system design

open access: yesAnnals 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]

open access: yesThe 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]

open access: yesThe 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 ...
