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

Ice sheet response to forced changes—such as that from anthropogenic climate forcing—is
closely regulated by two‐way interactions with other components of the Earth system. These …

Seasonal acceleration of the Greenland Ice Sheet is influenced by the dynamic response of
the subglacial hydrologic system to variability in meltwater delivery to the bed, via crevasses …

Ice flow along land-terminating margins of the Greenland Ice Sheet (GIS) varies
considerably in response to fluctuating inputs of surface meltwater to the bed of the ice …

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 …

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 …

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 …

We describe and evaluate version 2.1 of the Community Ice Sheet Model (CISM). CISM is a
parallel, 3-D thermomechanical model, written mainly in Fortran, that solves equations for …

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 …

Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is
a critical component of the Greenland Ice Sheet system. Despite considerable research …
