The detailed net mass balance of the Ice plain on Ice Stream B, Antarctica: a geographic information system approach
Abstract Field data of ice thickness, velocity and accumulation of the ice plain region of Ice Stream B, Antarctica, are organized into a geographic information system (GIS) and used to calculate the spatial pattern of net mass balance. Overall, the ice plain is thickening at a rate of 0.13 ± 0.05 m...
