Surface Melt and Runoff on Antarctic Ice Shelves at 1.5°C, 2°C, and 4°C of Future Warming
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

Brief communication: A submarine wall protecting the Amundsen Sea intensifies melting of neighboring ice shelves [PDF]
The Cryosphere, 2019 Disintegration of ice shelves in the Amundsen Sea, in front of the West Antarctic Ice Sheet, has the potential to cause sea level rise by inducing an acceleration of ice discharge from upstream grounded ice. Moore et al.

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 ...

Clouds drive differences in future surface melt over the Antarctic ice shelves
The Cryosphere, 2021 . Recent warm atmospheric conditions have damaged the ice shelves of the Antarctic Peninsula through surface melt and hydrofracturing, and could potentially initiate future collapse of other Antarctic ice shelves.

Basal terraces on melting ice shelves [PDF]
Geophysical Research Letters, 2014 AbstractOcean waters melt the margins of Antarctic and Greenland glaciers, and individual glaciers' responses and the integrity of their ice shelves are expected to depend on the spatial distribution of melt. The bases of the ice shelves associated with Pine Island Glacier (West Antarctica) and Petermann Glacier (Greenland) have similar geometries ...

Calving Fronts of Antarctica: Mapping and Classification
Remote Sensing, 2013 Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1

Channelization of plumes beneath ice shelves [PDF]
Journal of Fluid Mechanics, 2015 We study a simplified model of ice–ocean interaction beneath a floating ice shelf, and investigate the possibility for channels to form in the ice shelf base due to spatial variations in conditions at the grounding line. The model combines an extensional thin-film description of viscous ice flow in the shelf, with melting at its base driven by a ...

Diverging future surface mass balance between the Antarctic ice shelves and grounded ice sheet
The Cryosphere, 2020 . The future surface mass balance (SMB) will influence the ice dynamics and the contribution of the Antarctic ice sheet (AIS) to the sea level rise.

Journal of Glaciology, 1979 AbstractIce shelves form where ice flows off the Antarctic ice sheet onto the sea to produce rather flat slabs of floating ice which, for the theoretician, are the simplest of all large ice masses. Boundary conditions are well defined, conditions change very slowly over distances that are large compared with ice thickness, and horizontal velocities are

Roughness of Ice Shelves Is Correlated With Basal Melt Rates
, 2021 Ice shelf collapse could trigger widespread retreat of marine‐based portions of the Antarctic ice sheet. However, little is known about the processes that control the stability of ice shelves.
