Geophysical Research LettersTwo outstanding questions for the future of the Greenland Ice Sheet are (a) how enhanced meltwater draining beneath the ice will impact the behavior of large tidewater glaciers, and (b) to what extent tidewater glacier velocity is driven by changes at ...

Seasonal Acceleration of Petermann Glacier, Greenland, From Changes in Subglacial Hydrology
Geophysical Research Letters, 2023 Petermann Glacier is a major outlet glacier of northern Greenland that drains a marine‐based basin vulnerable to destabilization from enhanced oceanic and atmospheric forcings. Using satellite radar interferometry data from the Sentinel‐1a/b missions, we

Inversion of a glacier hydrology model [PDF]
Annals of Glaciology, 2016 The subglacial hydrologic system exerts strong controls on the dynamics of the overlying ice, yet the parameters that govern the evolution of this system are not widely known or observable.

The Importance of Solving Subglaciar Hydrology in Modeling Glacier Retreat: A Case Study of Hansbreen, Svalbard [PDF]
HydrologyArctic tidewater glaciers are retreating, serving as key indicators of global warming. This study aims to assess how subglacial hydrology affects glacier front retreat by comparing two glacier–fjord models of the Hansbreen glacier: one incorporating a ...

Basal conditions of Denman Glacier from glacier hydrology and ice dynamics modeling [PDF]
The Cryosphere, 2023 Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models, variability in subglacial hydrology ...

Technical note: Representing glacier geometry changes in a semi-distributed hydrological model [PDF]
Hydrology and Earth System Sciences, 2018 Glaciers play an important role in high-mountain hydrology. While changing glacier areas are considered of highest importance for the understanding of future changes in runoff, glaciers are often only poorly represented in hydrological models.

Sensitivity of subglacial drainage to water supply distribution at the Kongsfjord basin, Svalbard [PDF]
The Cryosphere, 2021 By regulating the amount, the timing, and the location of meltwater supply to the glacier bed, supraglacial hydrology potentially exerts a major control on the evolution of the subglacial drainage system, which in turn modulates ice velocity.
