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

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.

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

On the Multiscale Oceanic Heat Transports Toward the Bases of the Antarctic Ice Shelves
Ocean-Land-Atmosphere Research, 2023 The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change. The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic ice shelves.

Journal of Climate, 2022 We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq, %) and intensity (MPI-int, K) of daily maximum summer temperatures exceeding a melt threshold of 273.15 K.

Communications Earth & Environment, 2022 The Southern Hemisphere cryosphere has recently shown regionally-contrasted responses to climate change, in particular to the positive phases of the Southern Annular Mode.

Brief communication: widespread potential for seawater infiltration on Antarctic ice shelves [PDF]
The Cryosphere, 2018 Antarctica's future contribution to sea level change depends on the fate of its fringing ice shelves. One factor which may affect the rate of iceberg calving from ice shelves is the presence of liquid water, including the percolation of seawater into ...

Eddy and tidal driven basal melting of the Totten and Moscow University ice shelves
Frontiers in Marine Science, 2023 The mass loss from the neighboring Totten and Moscow University ice shelves is accelerating and may raise global sea levels in coming centuries. Totten Glacier is mostly based on bedrock below sea level, and so is vulnerable to warm water intrusion ...
