Extensive inland thinning and speed-up of Northeast Greenland Ice Stream
Over the past two decades, ice loss from the Greenland ice sheet (GrIS) has increased
owing to enhanced surface melting and ice discharge to the ocean,,,–. Whether continuing …

A consistent framework for coupling basal friction with subglacial hydrology on hard‐bedded glaciers
Below hard‐bedded glaciers, both basal friction and distributed subglacial drainage are
thought to be controlled by a network of cavities. Previous coupled hydro‐mechanical …

Icequake insights on transient glacier slip mechanics near channelized subglacial drainage
Glacier slip modulates sea-level rise. Most slip models assume quasi-equilibrium process
dynamics and debris-free basal ice, but observations regularly show debris-rich basal ice …

Threshold response to melt drives large-scale bed weakening in Greenland
Ice speeds in Greenland are largely set by basal motion, which is modulated by meltwater
delivery to the ice base,–. Evidence suggests that increasing melt rates enhance the …

Characterizing sediment flux of deforming glacier beds
Deformation of subglacial sediment during basal slip shapes the beds of many fast‐flowing
glaciers and ice streams. The resultant sediment flux impacts glacier dynamics and rates of …

Transient evolution of basal drag during glacier slip
Glacier slip is usually described using steady-state sliding laws that relate drag, slip velocity
and effective pressure, but where subglacial conditions vary rapidly transient effects may …

Wintertime supraglacial lake drainage cascade triggers large‐scale ice flow response in Greenland
N Maier, JK Andersen, J Mouginot… - Geophysical …, 2023 - Wiley Online Library
Surface melt forces summertime ice‐flow accelerations on glaciers and ice sheets. Here, we
show that large meltwater‐forced accelerations also occur during wintertime in Greenland …

Advances in monitoring glaciological processes in Kalallit Nunaat (Greenland) over the past decades
Greenland's glaciers have been retreating, thinning and accelerating since the mid-1990s,
with the mass loss from the Greenland Ice Sheet (GrIS) now being the largest contributor to …

Numerical approximation of viscous contact problems applied to glacial sliding
GG de Diego, PE Farrell, IJ Hewitt - Journal of Fluid Mechanics, 2022 - cambridge.org
Viscous contact problems describe the time evolution of fluid flows in contact with a surface
from which they can detach and reattach. These problems are of particular importance in …
