Recent observations of dynamic water systems beneath the Greenland and Antarctic ice
sheets have sparked renewed interest in modelling subglacial drainage. The foundations of …

When large volumes of meltwater arrive suddenly at the glacier bed, the capacity of
subglacial conduits is exceeded, generating transiently high fluid pressures. Yet we …

Penetration of surface meltwater to the bed of the Greenland Ice Sheet each summer causes
an initial increase in ice speed due to elevated basal water pressure, followed by slowdown …

Subglacial hydrology is a leading control on basal friction and the dynamics of glaciers and
ice sheets. At low discharge, subglacial water flows through high-pressure, sheet-like …

The subglacial drainage system is one of the main controls on basal sliding, but remains
only partially understood. Here we use an 8-year dataset of borehole observations on a …

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 …

Below hard‐bedded glaciers, both basal friction and distributed subglacial drainage are
thought to be controlled by a network of cavities. Previous coupled hydro‐mechanical …

Major uncertainties in the response of ice sheets to environmental forcing are due to
subglacial processes. These processes pertain to the type of sliding or friction law as well as …

On most glaciers and ice sheet outlets the majority of motion is due to basal slip, a
combination of basal sliding and bed deformation. The importance of basal water in …

The flow speed of the Greenland Ice Sheet changes dramatically in inland regions when
surface meltwater drains to the bed. But ice-sheet discharge to the ocean is dominated by …
