Melting is pervasive along the ice surrounding Antarctica. On the surface of the grounded ice
sheet and floating ice shelves, extensive networks of lakes, streams and rivers both store …

Surface meltwater drains across ice sheets, forming melt ponds that can trigger ice-shelf
collapse,, acceleration of grounded ice flow and increased sea-level rise,,. Numerical …

Meltwater stored in ponds and crevasses can weaken and fracture ice shelves, triggering
their rapid disintegration. This ice-shelf collapse results in an increased flux of ice from …

In the coming decades, significant changes in the polar regions will increase the contribution
of ice sheets to global sea-level rise. Under the ice streams and outlet glaciers that deliver …

Atmospheric warming is increasing surface melting across the Antarctic Peninsula, with
unknown impacts upon glacier dynamics at the ice-bed interface. Using high-resolution …

Recent major melting events in West Antarctica have raised concerns about a potential
hydrofracturing and ice shelf instability. These events often share common forcings of …

Surface melt and subsequent firn air depletion can ultimately lead to disintegration of
Antarctic ice shelves, causing grounded glaciers to accelerate and sea level to rise. In the …

The stability of ice sheets and their contributions to sea level are modulated by high-
pressure water that lubricates the base of the ice, facilitating rapid flow into the ocean. In …

Surface melt ponds form intermittently on several Antarctic ice shelves. Although implicated
in ice-shelf break up, the consequences of such ponding for ice formation and ice-shelf …

Meltwater generated beneath the Antarctic Ice Sheet exerts a strong influence on the speed
of ice flow, in particular for major ice streams,. The subglacial meltwater also influences …
