Abstract Purpose of the Review This review discusses the role that meltwater plays within
the Greenland ice sheet system. The ice sheet's hydrology is important because it affects …

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

Intense rainfall events significantly affect Alpine and Alaskan glaciers through enhanced
melting, ice-flow acceleration and subglacial sediment erosion, yet their impact on the …

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 …

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 …

Remote sensing is commonly used to monitor supraglacial lakes on the Greenland Ice
Sheet (GrIS); however, most satellite records must trade off higher spatial resolution for …

Uncertainty remains about how the surface hydrology of the Greenland ice sheet influences
its subglacial drainage system, affecting basal water pressures and ice velocities …

Meltwater drainage through ice sheets has recently been a key focus of glaciological
research due to its influence on the dynamics of ice sheets in a warming climate. However …

Meltwater drainage across the surface of the Greenland ice sheet (GrIS) is well constrained
by measurements and modeling, yet despite its critical role, knowledge of its transit through …

Supraglacial lakes on the Greenland Ice Sheet are expanding inland, but the impact on ice
flow is equivocal because interior surface conditions may preclude the transfer of surface …
