Can rifts alter ocean dynamics beneath ice shelves? [PDF]
The Cryosphere, 2023 Land ice discharge from the Antarctic continent into the ocean is restrained by ice shelves, floating extensions of grounded ice that buttress the glacier outflow.

The role of föhn winds in eastern Antarctic Peninsula rapid ice shelf collapse [PDF]
The Cryosphere, 2022 Ice shelf collapse reduces buttressing and enables grounded glaciers to contribute more rapidly to sea-level rise in a warming climate. The abrupt collapses of the Larsen A (1995) and B (2002) ice shelves on the Antarctic Peninsula (AP) occurred, at ...

Data initiatives for ocean-driven melt of Antarctic ice shelves [PDF]
, 2022 Ocean-driven melt of Antarctic ice shelves is an important control on mass loss from the ice sheet, but is complex to study due to significant variability in melt rates both spatially and temporally. Here we assess the strengths and weakness of satellite

Modeling Ice Shelf/Ocean Interaction in Antarctica: A Review [PDF]
Oceanography, 2016 The most rapid loss of ice from the Antarctic Ice Sheet is observed where ice streams flow into the ocean and begin to float, forming the great Antarctic ice shelves that surround much of the continent.

A 15-year circum-Antarctic iceberg calving dataset derived from continuous satellite observations [PDF]
Earth System Science Data, 2021 Iceberg calving is the main process that facilitates the dynamic mass loss of ice sheets into the ocean, which accounts for approximately half of the mass loss of the Antarctic ice sheet.

International Journal of Digital Earth, 2023 Ice shelves play an essential role in the dynamics of the Antarctic ice sheet. The surface meltwater is important, as it can irreversibly weaken ice shelves by exerting additional hydrostatic pressure.

Variable temperature thresholds of melt pond formation on Antarctic ice shelves
Nature Climate Change, 2023 Melt ponding is an important process for the stability of ice shelves. Here the authors estimate the temperature thresholds at which melt ponding emerges over Antarctic ice shelves and find that cold and dry ice shelves are more vulnerable to melt ...

Creep deformation and buttressing capacity of damaged ice shelves: theory and application to Larsen C ice shelf [PDF]
The Cryosphere, 2013 Around the perimeter of Antarctica, much of the ice sheet discharges to the ocean through floating ice shelves. The buttressing provided by ice shelves is critical for modulating the flux of ice into the ocean, and the presently observed thinning of

Widespread slowdown in thinning rates of West Antarctic ice shelves
The Cryosphere, 2023 . Antarctica's floating ice shelves modulate discharge of grounded ice into the ocean by providing a backstress. Ice shelf thinning and grounding line retreat have reduced this backstress, driving rapid drawdown of key unstable areas of the Antarctic Ice

Anomalous Meltwater From Ice Sheets and Ice Shelves Is a Historical Forcing
Geophysical Research Letters, 2023 Recent mass loss from ice sheets and ice shelves is now persistent and prolonged enough that it impacts downstream oceanographic conditions. To demonstrate this, we use an ensemble of coupled GISS‐E2.1‐G simulations forced with historical estimates of ...
