This dataset presents subglacial provinces mapped beneath the Greenland Ice Sheet using seismic tomography, gravity and magnetic anomalies, subglacial topography and the surface expression thereof. This dataverse deposit contains: (1) a "flow-aware" hillshade model of the ice sheet as a raster, (2) the MATLAB script associated with generating the flow-aware hillshade; (3) all traced lineations from the ice-sheet surface as shapefile polylines (4) the seismic tomography results considered in this study that were not previously available as rasters; (5) the apparent boundaries in geophysical fields as shapefile polylines; (6) the subglacial geologic provinces as shapefile polygons. ...
