Marine ice sheets are highly sensitive to submarine melting in their grounding zones, where
they transition between grounded and floating ice. Recently published studies of the …

Climate change could potentially destabilize marine ice sheets, which would affect
projections of future sea-level rise,,,. Specifically, an instability mechanism,,, has been …

Ice-sheet grounding lines are sensitive to initial conditions and to small perturbations in
boundary conditions, based on new model results coupling ocean and ice flow. To study ice …

Ice melt processes that take place at the ice–ocean boundary of Greenland and Antarctic
glaciers play a pivotal role in their evolution and contribution to sea-level rise, but …

Determining the position and stability of the grounding line of a marine ice sheet is a major
challenge for ice-sheet models. Here, we investigate the role of lateral shear and ice-shelf …

It has been suggested that rapid thinning of the West Antarctic ice sheet is due to increased
melting under ice shelves caused by a gradual ocean warming (Shepherd et al., 2004) …

Observations of ocean-driven grounding line retreat in the Amundsen Sea Embayment in
Antarctica give rise to the question of a collapse of the West Antarctic Ice Sheet. Here we …

The “marine ice-sheet instability” hypothesis continues to be used to interpret the observed
mass loss from the Antarctic and Greenland ice sheets. This hypothesis has been developed …

Observations of ocean-driven grounding-line retreat in the Amundsen Sea Embayment in
Antarctica raise the question of an imminent collapse of the West Antarctic Ice Sheet. Here …

Large parts of the Antarctic ice sheet lying on bedrock below sea level may be vulnerable to
marine-ice-sheet instability (MISI), a self-sustaining retreat of the grounding line triggered by …
