Understanding Greenland ice sheet (GrIS) hydrology is essential for evaluating response of
ice dynamics to a warming climate and future contributions to global sea level rise. Recently …

The manner by which meltwater drains through a glacier is critical to ice dynamics, runoff
characteristics, and water quality. However, much of the contemporary knowledge relating to …

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 …

Mass loss from the Greenland ice sheet contributes significantly to present sea level rise.
High meltwater runoff is responsible for half of Greenland's mass loss. Surface melt has …

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 …

Several decades of ice‐penetrating radar surveys of the Greenland and Antarctic ice sheets
have observed numerous widespread internal reflections. Analysis of this radiostratigraphy …

High resolution measurements of ice motion along a∼ 120 km transect in a land‐
terminating section of the GrIS reveal short‐term velocity variations (< 1 day), which are …

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 …

The impact of increasing summer melt on the dynamics and stability of the Greenland Ice
Sheet is not fully understood. Mounting evidence suggests seasonal evolution of subglacial …

Abstract Runoff from the Greenland Ice Sheet has increased over recent decades affecting
global sea level, regional ocean circulation, and coastal marine ecosystems, and it now …
