Microbiology: lessons from a first attempt at Lake Ellsworth [PDF]
, 2015 During the attempt to directly access, measure and sample Subglacial Lake Ellsworth in 2012–2013, we conducted microbiological analyses of the drilling equipment, scientific instrumentation, field camp and natural surroundings.

Models of ice melting and edifice growth during subglacial basaltic eruptions. [PDF]
, 2007 Models of the early stages of basaltic eruptions beneath temperate glaciers are presented that consider the evolving sizes of volcanic edifices emplaced within subglacial cavities.

Distribution and dynamics of Greenland subglacial lakes [PDF]
Nature Communications, 2019 Abstract Few 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 ...

Products of an effusive subglacial rhyolite eruption: Blahnukur, Torfajokull, Iceland. [PDF]
, 2001 . We present field observations from Blahnukur, a small volume (400 m thick. Lithofacies associations attest to complex patterns of volcano-ice interaction.

Melting of the glacier base during a small-volume subglacial rhyolite eruption: evidence from Blahnukur, Iceland. [PDF]
, 2002 Although observations of recent volcanic eruptions beneath Vatnajokull, Iceland have improved the understanding of ice deformation and meltwater drainage, little is known about the processes that occur at the glacier base.

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

Subglacial Lake Ellsworth: a candidate for in situ exploration in West Antarctica [PDF]
, 2004 Radio-echo sounding reveals a 10 km-long lake beneath similar to3.4 km of ice near the Ellsworth Mountains in West Antarctica, 20 km from the ice divide. Subglacial Lake Ellsworth is located within a distinct topographic hollow, which is similar to1.5 km

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

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.

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 ...
