Deep clustering in subglacial radar reflectance reveals subglacial lakes

The Cryosphere
Ice-penetrating radar (IPR) imaging is a valuable tool for observing the internal structure and bottom of ice sheets. Subglacial water bodies, also known as subglacial lakes, generally appear as distinct, bright, flat, and continuous reflections in IPR images.

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

, 2014
We present radio-echo sounding data and satellite imagery, revealing a series of ancient large sub-parallel subglacial channels preserved in the region between the Möller and Foundation Ice Streams, West Antarctica.

Tracking the Filling, Outburst Flood and Resulting Subglacial Water Channel From a Large Canadian Arctic Subglacial Lake

Geophysical Research Letters
We use digital elevation models (DEMs) and ICESat‐2 data to study the filling and outflow from a large subglacial lake under Manson Icefield in the Canadian Arctic. When full, the lake is ∼17 × 3 km with an area of 52 km2.

Using Multimission Satellite Altimetry to Monitor Subglacial Hydrological Activities in the Totten Basin, East Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In East Antarctica, the largest thinning rates are observed at Totten Glacier in recent years. Hydrologic activity of the three active subglacial lakes (Totten1, Totten2, and Wilkes1) located on Totten Glacier may affect the ice sheet mass balance in the

Dynamic subglacial meltwater history archived in Antarctic subglacial lake sediments

Geological Society of America Bulletin
Abstract There is a paucity of records on decadal to millennial scales archiving the evolution of the Antarctic subglacial hydrologic system, leaving a gap in our knowledge of the links between meltwater drainage and ice behavior. We employed a suite of sedimentological and geochemical methods to assess the stratigraphic distribution of ...
