| Summary: | This dissertation uses the 3D, finite-element, full-Stokes, open-source model Elmer/Ice to investigate the coupled dynamics of the ice-calving-subglacial-hydrology-plume system at Store Glacier, a large, fast-flowing tidewater outlet glacier on the west coast of Greenland. Understanding these large outlet glaciers is critical to being able to accurately predict the future evolution of the Greenland Ice Sheet. This study therefore presents a three-week record of calving activity at Store Glacier, gathered in July 2017 using a terrestrial radar interferometer. This record is the longest and most detailed yet produced for a Greenlandic tidewater glacier and shows the complex and time-varying nature of calving at Store Glacier. In parallel, an uncoupled model of subglacial hydrology and plume melting at the calving front is developed within the Elmer/Ice framework and applied to Store Glacier to investigate seasonal differences in hydrology. Overall, the dynamic nature and key role of the subglacial hydrological ... |
