SHMIP the Subglacial Hydrology Model Intercomparison Project [PDF]
Journal of Glaciology, 2018 Subglacial hydrology plays a key role in many glaciological processes, including ice dynamics via the modulation of basal sliding. Owing to the lack of an overarching theory, however, a variety of model approximations exist to represent the subglacial ...

SHAKTI: Subglacial Hydrology and Kinetic, Transient Interactions v1.0 [PDF]
Geoscientific Model Development, 2018 Subglacial hydrology has a strong influence on glacier and ice sheet dynamics, particularly through the dependence of sliding velocity on subglacial water pressure.

Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica [PDF]
The Cryosphere, 2020 Subglacial water plays an important role in ice sheet dynamics and stability. Subglacial lakes are often located at the onset of ice streams and have been hypothesised to enhance ice flow downstream by lubricating the ice–bed interface.

Subglacial Hydrology and the Formation of Ice Streams [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Antarctic ice streams are associated with pressurized subglacial meltwater but the role this water plays in the dynamics of the streams is not known. To address this, we present a model of subglacial water flow below ice sheets, and particularly below ice streams.

Annals of Glaciology, 2022 Subglacial hydrology is an important component of the ice dynamic system in Antarctica but is challenging to investigate due to the large spatial scales of the catchment systems, the ice thickness, and remote location.

A double continuum hydrological model for glacier applications [PDF]
The Cryosphere, 2014 The flow of glaciers and ice streams is strongly influenced by the presence of water at the interface between ice and bed. In this paper, a hydrological model evaluating the subglacial water pressure is developed with the final aim of ...

Accelerating Subglacial Hydrology for Ice Sheet Models With Deep Learning Methods
Geophysical Research LettersSubglacial drainage networks regulate the response of ice sheet flow to surface meltwater input to the subglacial environment. Simulating subglacial hydrology evolution is critical to projecting ice sheet sensitivity to climate, and contribution to sea ...

Subglacial Hydrology and Ice Stream Margin Locations [PDF]
Journal of Geophysical Research F: Earth Surface, 2015 Abstract Fast‐flowing ice streams in West Antarctica are separated from the nearly stagnant ice in the adjacent ridge by zones of highly localized deformation known as shear margins. It is presently uncertain what mechanisms control the location of shear margins and possibly allow them to migrate.

Subglacial Hydrology as a Control on Emergence,Scale, and Spacing of Ice Streams [PDF]
Journal of Geophysical Research F: Earth Surface, 2015 AbstractObservations have long associated ice streams with the presence of meltwater at the bed. More recently, theoretical models have been able to reproduce ice stream behavior as a consequence of the coupled dynamics of ice and subglacial meltwater.

Antarctic Wide Subglacial Hydrology Modeling
Geophysical Research LettersGlobal sea levels are rising due, in large part, to the increase in the rate of melting of ice sheets as a direct result of climate change. A large fraction of uncertainty in future sea level rise comes from limited understanding of basal conditions ...
