Greenland Subglacial Lakes Detected by Radar [PDF]

Geophysical Research Letters, 2013
AbstractSubglacial lakes are an established and important component of the basal hydrological system of the Antarctic ice sheets, but none have been reported from Greenland. Here we present airborne radio echo sounder (RES) measurements that provide the first clear evidence for the existence of subglacial lakes in Greenland.

Antarctic Subglacial Lakes

Earth-Science Reviews, 2000
Abstract Antarctic subglacial lakes were first identified by Robin et al. (1970) after airborne radio-echo sounding (RES) investigations of the ice-sheet interior. Recently, satellite altimetry was used to measure anomalous near-flat regions on the ice-sheet surface that represent a manifestation of the subglacial lake beneath.

Geology and Environments of Subglacial Lake Vostok [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2016
The reconstruction of the geological (tectonic) structure and environments of subglacial Lake Vostok is based on geophysical surveys and the study of mineral particles found in cores of accreted ice and frozen lake water (sampled after the lake was unsealed).

Clean Access, Measurement, and Sampling of Ellsworth Subglacial Lake: A Method for Exploring Deep Antarctic Subglacial Lake Environments [PDF]

Reviews of Geophysics, 2012
Antarctic subglacial lakes are thought to be extreme habitats for microbial life and may contain important records of ice sheet history and climate change within their lake floor sediments. To find whether or not this is true, and to answer the science questions that would follow, direct measurement and sampling of these environments are required. Ever

Subglacial Lakes and Jökulhlaups in Iceland

Global and Planetary Change, 2003
Active volcanoes and hydrothermal systems underlie ice caps in Iceland. Glacier-volcano interactions produce meltwater that either drains toward the glacier margin or accumulates in subglacial lakes. Accumulated meltwater drains periodically in jokulhlaups from the subglacial lakes and occasionally during volcanic eruptions.
