Antarctic subglacial hydrology: current knowledge and future challenges [PDF]
Antarctic Science, 2014 Flood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the ...

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 ...

The past, present, and future evolution of Aurora Subglacial Basin’s subglacial drainage system [PDF]
Nature CommunicationsAurora Subglacial Basin (ASB) in East Antarctica is among the most rapidly changing regions in Antarctica. Beneath the ASB, subglacial drainage networks allow for fast ice flow and facilitate mass losses by eroding the coastal ice shelves.

Spatially distributed runoff at the grounding line of a large Greenlandic tidewater glacier inferred from plume modelling [PDF]
Journal of Glaciology, 2017 Understanding the drivers of recent change at Greenlandic tidewater glaciers is of great importance if we are to predict how these glaciers will respond to climatic warming.

Surging of a Hudson Strait-scale ice stream: subglacial hydrology matters but the process details mostly do not [PDF]
The Cryosphere, 2023 While subglacial hydrology is known to play a role in glacial dynamics on sub-annual to decadal scales, it remains unclear whether subglacial hydrology plays a critical role in ice sheet evolution on centennial or longer timescales.

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.

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.

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 ...

Journal of Glaciology, 2023 Hydrologic pathways beneath ice sheets and glaciers play an important role in regulating ice flow. Antarctica has experienced, and will continue to experience, changes in ice dynamics and geometry, but the associated changes in subglacial hydrology have ...

The role of subglacial hydrology in ice streams with elevated geothermal heat flux
Journal of Glaciology, 2020 The spatial distribution of geothermal heat flux (GHF) under ice sheets is largely unknown. Nonetheless, it is an important boundary condition in ice-sheet models, and suggested to control part of the complex surface velocity patterns observed in some ...
