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 …

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 …

Ice sheets are currently ignored in global methane budgets,. Although ice sheets have been
proposed to contain large reserves of methane that may contribute to a rise in atmospheric …

Mass loss from the Greenland ice sheet (GrIS) has increased over the last two decades in
response to changes in global climate, motivating the scientific community to question how …

Abstract The Greenland ice sheet (GrIS) is at present the largest single contributor to global-
mass-induced sea-level rise, primarily because of Arctic amplification on an increasingly …

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 …

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

Seasonal glacier ice velocities are important for understanding controlling mechanisms of
ice flow. For many Greenlandic glaciers, however, these measurements are limited by low …

Subglacial water flow strongly modulates glacier basal motion, which itself strongly
influences the contributions of glaciers and ice sheets to sea level rise. However, our …

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 …
