Rhombohedral crevasse-fill ridges at the marine margin of a surging Svalbard ice cap
The ice cap of Ausftonna in eastern Svalbard is the largest in the Eurasian Arctic at 8,000 km2 and has about 200 km of marine-terminating ice cliffs (Dowdeswell et al. 2008). Several of its drainage basins are of surge-type (Meier & Post 1969) and between 1936 and 1938 one of these basins, Brås...
