Extended Data Fig. 9: Ice shelf basal mass balance and ice sheet surface elevation change.
From: A West Antarctic grounding-zone environment shaped by episodic water flow
Ice shelf basal mass balance estimated using CryoSat-2 radar altimetry [Previously published data from:49] and onshore surface elevation change estimated in 500 m tiles using elevation data generated using swath processed CryoSat-2 data34 following the method of27. Contours on the ice shelf at 0.5 m a−1 intervals. Borehole access location shown by red triangle. Grounding line shown as black line35.
