Extended Data Fig. 5: Steady-state calving-flux calculation.
To obtain steady-state calving flux, we calculate pixel centre locations (x1,y1) of a 240-m resolution grid after one year of ice displacement. We use (x1,y1) as query points to linearly interpolate a binary ice mask, which gives the fraction of each grid cell that is still within the initial mask after a year of displacement. Calving flux is calculated by multiplying the fraction of ice that has calved after a year of displacement by the area, thickness, and density of ice in each grid cell.
