| 英文摘要: | Marine-terminating outlet glaciers drain 88% of the Greenland Ice Sheet and are responsible for at least half of the ice sheet's net annual mass loss, which at present is around 200 km3/year. Understanding the processes that drive the fast flow of these glaciers is crucial because a growing body of evidence points to a strong, but spatially varied and often complex, response to both oceanographic and atmospheric forcing. While the bed of glaciers elsewhere is known to strongly influence the flow of ice, no observations have ever been made from beneath a marine-terminating glacier in Greenland; a potential and likely cause of significant error in current predictions of sea level rise. This project will correct this paucity of observational constraint by gaining access to the bed of a major marine-terminating outlet glacier (Store Gletscher) in West Greenland, in order to observe and characterise the basal interface. With instruments deployed at the bed and on the glacier's surface and forefield, the project will fully resolve the basal control on ice flow and the glacier's response to iceberg calving, including the effects of meltwater input to the bed. The observational outcome will inform the glacier's sensitivity to atmospheric as well as oceanographic forcing while also enabling numerical ice flow modelling of unprecedented detail and accuracy. |
