Where the Brunt Ice Shelf, growing inexorably from the edge of the Antarctic Ice Sheet, meets a obstacle protruding from the sea floor, the McDonald Ice Rumples are formed – a region of ice deformation, rift generation and shelf fracture. The animation combines images every week or so from the ESA Copernicus Sentinel-1 satellites.

In recent years fracturing has increased and Brunt Ice Shelf will soon lose an area the size of Greater London to a large calving event. Although significant in the known history of this ice shelf, this is believed to be a natural part of the cycle of growth and decay (de Rydt et al., 2019).
