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...
