Abstract: Estimates of ice loss from the West Antarctic Ice Sheet depend on accurate modelling of dynamic thinning, for which knowledge of basal topography is needed; here, ice-penetrating radar, gravity and magnetic measurements reveal a subglacial rift basin that acts as a conduit between the Bellingshausen Sea and the ice-sheet interior.
