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 …

Grounding lines are a key indicator of ice-sheet instability, because changes in their position
reflect imbalance with the surrounding ocean and affect the flow of inland ice. Although the …

As continental ice from Antarctica reaches the grounding line and begins to float, its
underside melts into the ocean. Results obtained with satellite radar interferometry reveal …

Abstract Changes to the grounding line, where grounded ice starts to float, can be used as a
remotely sensed measure of ice‐sheet susceptibility to ocean‐forced dynamic thinning …

Observations from satellite and airborne platforms are combined with model calculations to
infer the nature and efficiency of basal melting of the Pine Island Glacier ice shelf, West …

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 …

Much of the threshold behavior of marine ice sheets is thought to result from processes
occurring at the grounding zone, where the ice sheet transitions into the ice shelf. At short …

By thinning and accelerating, West Antarctic ice streams are contributing about 10% of the
observed global sea level rise. Much of this ice loss is from Pine Island Glacier, which has …

Grounding line dynamics are key to our understanding of marine ice sheets such as the
West Antarctic Ice Sheet (WAIS). We present an accurate and rapid method for locating …

The glaciers flowing into the Amundsen Sea Embayment, West Antarctica, have undergone
acceleration and grounding line retreat over the past few decades that may yield an …
