Polar Monitor - Ice sheet drainage basins - Antarctica, 2010-2021

The drainage divides of ice sheets separate the overall glaciated area into multiple sectors. These drainage basins are essential for partitioning mass changes of the ice sheet, as they specify the area over which basin specific measurements are integrated. In (Krieger et al., 2020) we developed a modified watershed algorithm for delineating individual glaciers and applied it to the Northeast Greenland sector. Here we extended the processing to the entire Antarctic Ice Sheet.
