The change over 2013, 2014 and 2015.

The 5 km long Blankfjellbreen is surging out into Nathorstbreen in Van Keulenfjorden, Svalbard. In the upper parts, its reservoirs are emptied, creating vertical cliffs where the ice is separated. In the lower parts, the increase in ice flux creates a sizeable bulge.

2013 is shown in a grey omnidirectional hillshade, and the subsequent models are colour coded to show the change from 2013, measured normal to the surface.
