Understanding the processes influencing supraglacial stream discharge on the Greenland ice sheet ...
The Greenland ice sheet is one of the largest sources of cryospheric contribution to the global sea-level rise. The recent mass loss from the Greenland ice sheet is largely due to the increased meltwater runoff from the surface through supraglacial (on the top of the glacier) stream networks. Region...

| Summary: | The Greenland ice sheet is one of the largest sources of cryospheric contribution to the global sea-level rise. The recent mass loss from the Greenland ice sheet is largely due to the increased meltwater runoff from the surface through supraglacial (on the top of the glacier) stream networks. Regional climate models are the primary tools for predicting Greenland’s contribution to sea-level rise; however, their validation is limited due to lack of in-situ observations of surface runoff through supraglacial stream networks. Moreover, these models do not capture the impact of some surface hydrological processes on runoff, leading to overestimation of modeled runoff from the ice sheet surface. This dissertation presents a novel data set that includes an unprecedented long record of stream discharge from a supraglacial catchment in southwest Greenland throughout almost an entire melt season. The study investigates stream discharge and its drivers while also examining how well the models simulate stream discharge. ... |
