Ice surface anomalies, hydraulic potential and subglacial lake chains in East Antarctica

Summary The most recent subglacial lake inventories and classification methods further demonstrate the strong correlation between subglacial lakes and flat anomalies on the ice surface. A reanalysis of older radar sounding data shows that several subglacial basins previously identified as “lake less...

Description
Summary:Summary The most recent subglacial lake inventories and classification methods further demonstrate the strong correlation between subglacial lakes and flat anomalies on the ice surface. A reanalysis of older radar sounding data shows that several subglacial basins previously identified as “lake less ” may actually contain multiple lakes along with other important subglacial hydraulic features. The combined use of radar sounding and satellite surface mapping is allowing unprecedented detail in the mapping of subglacial hydraulic systems in East Antarctica.
