The CryosphereAbstract. Subglacial lakes beneath Antarctic glaciers are pivotal in advancing our understanding of cryosphere dynamics, basal hydrology, and microbial ecosystems. We investigate the internal structure and physical properties of Subglacial Lake D2 (SLD2), which is located beneath David Glacier in East Antarctica, using seismic data acquired during the ...

Advances in modelling subglacial lakes and their interaction with the Antarctic ice sheet [PDF]
, 2015 Subglacial lakes have long been considered hydraulically isolated water bodies underneath ice sheets. This view changed radically with the advent of repeat-pass satellite altimetry and the discovery of multiple lake discharges and water infill ...

Dynamic subglacial meltwater history archived in Antarctic subglacial lake sediments
Geological Society of America BulletinAbstract 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 ...

Lakes and subglacial hydrological networks around Dome C, East Antarctica [PDF]
, 2003 Precise topography from European Remote-sensing Satellite radar altimetry and high density of airborne radio-echo sounding in the area surrounding Dome C, Antarctica, show a link between surface features and subglacial lakes.

Physiography and tectonic setting of the subglacial lake district between Vostok and Belgica Subglacial Highlands (Antartica) [PDF]
, 2006 We present the interpretation of 11 radio echo-sounding (RES) missions carried out over the Vostok–Dome Concordia region during the Italian Antarctic expeditions in the period 1995– 2001.
