Predicted subglacial lakes in Antarctica

This data set comprises the geographical coordinates of modelled outlines of 31 new subglacial lakes in Dronning Maud Land, Antarctica, using the general hydraulic potential equation (Shreve 1972), Bedmap2 data sets (Fretwell and others, 2013), and AWI airborne radio-echo sounding data collected bet...

Description
Summary:This data set comprises the geographical coordinates of modelled outlines of 31 new subglacial lakes in Dronning Maud Land, Antarctica, using the general hydraulic potential equation (Shreve 1972), Bedmap2 data sets (Fretwell and others, 2013), and AWI airborne radio-echo sounding data collected between 1994–2013. The modelling was conducted in 2015 using the Bedmap2 bedrock topography and ice thickness data (Fretwell and others, 2013) at 5 km grid cell size. Determined sinks in the hydraulic potential were checked for coverage by AWI airborne radio-echo sounding data. Based on the structure of the subglacial reflexions, sinks were classified as subglacial lakes. The outline of like that identified subglacial lakes are presented here. Not all calculated sinks were covered by AWI airborne radio-echo sounding data.
