Subglacial sediments are an important control on fast flowing ice in West Antarctica but their spatial distribution over catchment-wide areas is still largely unknown. Previously, airborne gravity anomalies could not clearly image sedimentary basins beneath the ice because broad, crustal-scale gravi...
