On the left: Surface topography and ice velocities. On the right: Bed topography beneath the ice sheet inferred from mass conservation.

Black squares are 50 km x 50 km and the vertical exaggeration factor is 3. Surface elevation is from GIMP (Howat et al. 2014), surface velocities from Rignot and Mouginot 2012, bed topography from Morlighem et al. 2014.
