Scientists have mapped the complex mesoscale landscapes (2 to 30 km) beneath the Antarctic ice sheet from space using high-resolution satellite data and ice flow physics.[1][5] The method uses the influence of the underlying relief on the surface of the ice, where the thickness of the ice reaches approximately 3 km and the stresses are transmitted over a distance 10 times this thickness.[1] In doing so, they identified topographic features in the deep interior of Antarctica that previous methods with data spacing of 10 to 100 km could not distinguish.[1] The results complement the Bedmap3 map and contribute to the BedMachine project for modeling the slow-moving glacier interior.[1] The map reveals the continental dimensions of subglacial relief, including mountains, valleys, plains, basins, and lakes.[6] These findings help to understand the history of the largest glacier on Earth and to predict changes in the cryosphere.[1] The analysis relies on assumptions about ice deformation, basal sliding, and melting and freezing processes at the ice-rock interface.[1]
