Instantaneous Antarctic ice sheet mass loss driven by thinning ice shelves [PDF]
Geophysical Research Letters, 2019 Recent observations show that the rate at which the Antarctic ice sheet (AIS) is contributing to sea level rise is increasing. Increases in ice‐ocean heat exchange have the potential to induce substantial mass loss through the melting of its ice shelves.

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.

Progressive unanchoring of Antarctic ice shelves since 1973. [PDF]
NatureMass loss of the Antarctic Ice Sheet has been driven primarily by the thinning of the floating ice shelves that fringe the ice sheet1, reducing their buttressing potential and causing land ice to accelerate into the ocean2.

Surface Melt and Runoff on Antarctic Ice Shelves at 1.5°C, 2°C, and 4°C of Future Warming [PDF]
Geophysical Research Letters, 2021 The future surface mass balance (SMB) of Antarctic ice shelves has not been constrained with models of sufficient resolution and complexity. Here, we force the high‐resolution Modèle Atmosphérique Régional with future simulations from four CMIP models to

Supervised classification of slush and ponded water on Antarctic ice shelves using Landsat 8 imagery
Journal of Glaciology, 2022 Surface meltwater is becoming increasingly widespread on Antarctic ice shelves. It is stored within surface ponds and streams, or within firn pore spaces, which may saturate to form slush.

Evaluation of four calving laws for Antarctic ice shelves [PDF]
The Cryosphere, 2023 Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve icebergs and how fast they flow determine whether they advance, retreat, or ...

Predicting the steady-state isochronal stratigraphy of ice shelves using observations and modeling [PDF]
The Cryosphere, 2022 Ice shelves surrounding the Antarctic perimeter moderate ice discharge towards the ocean through buttressing. Ice-shelf evolution and integrity depend on the local surface accumulation, basal melting and on the spatially variable ice-shelf viscosity ...

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 ...

Explicit representation and parametrised impacts of under ice shelf seas in the z∗ coordinate ocean model NEMO 3.6 [PDF]
Geoscientific Model Development, 2017 Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Widespread movement of meltwater onto and across Antarctic ice shelves [PDF]
Nature, 2017 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.
