The cycling of carbon on Earth exerts a fundamental influence upon the greenhouse gas
content of the atmosphere, and hence global climate over millennia. Until recently, ice …

Glacier-erosion rates range across orders of magnitude, and much of this variation cannot
be attributed to basal sliding rates. Subglacial till acts as lubricating 'fault gouge'or 'sawdust' …

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 (GrIS) has increased over the last two decades in
response to changes in global climate, motivating the scientific community to question how …

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 …

Abstract The Greenland Ice Sheet is losing mass at an accelerating rate due to increased
surface melt and flow acceleration in outlet glaciers. Quantifying future dynamic …

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 …

Climatic changes over the last 50 years resulted in a decrease of permafrost extent, an
increase of permafrost temperature, and deepening of the active layer in numerous locations …

Abstract Distributed Acoustic Sensing (DAS) is a new technology in which seismic energy is
detected, at high spatial and temporal resolution, using the propagation of laser pulses in a …

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 …
