Abstract
To better understand recent rapid recession of marine-terminating glaciers in Greenland, we performed satellite and field observations near the calving front of Bowdoin Glacier, a 3 km wide outlet glacier in northwestern Greenland. Satellite data revealed a clear transition to a rapidly retreating phase in 2008 from a relatively stable glacier condition that lasted for more than 20 years. Ice radar measurements showed that the glacier front is grounded, but very close to the floating condition. These results, in combination with the results of ocean depth soundings, suggest bed geometry in front of the glacier is the primary control on the rate and pattern of recent rapid retreat. Presumably, glacier thinning due to atmospheric and/or ocean warming triggered the initial retreat.

Knut and Alice Wallenberg Foundation (KAW) and Swedish Research Council (VR) financed the Oden multibeam system and the installation was financed by the Swedish Maritime Administration. The Oden expeditions were organized by the Swedish Polar Research Secretariat. This Mapping Repository is a part of the Bert Bolin Centre for Climate Research data archive.
