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 …

Marine-geological and-geophysical data collected from the continental shelf in Pine Island
Bay, Antarctica, reveal a complex paleo-subglacial drainage system controlled by bedrock …

Rapid warming of the Antarctic Peninsula over the past several decades has led to
extensive surface melting on its eastern side, and the disintegration of the Prince Gustav …

Mass loss from the Antarctic ice sheet, Earth's largest freshwater reservoir, results directly in
global sea-level rise and Southern Ocean freshening. Observational and modeling studies …

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 …

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

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 …

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 …

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 …

Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool
and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the …
