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.

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]
, 2007 A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...

Journal of Geophysical Research: Oceans, 2021 The Filchner-Ronne Ice Shelf (FRIS) is characterized by moderate basal melt rates due to the near-freezing waters that dominate the wide southern Weddell Sea continental shelf.

Recent loss of floating ice and the consequent sea level contribution [PDF]
, 2010 We combine new and published satellite observations and the results of a coupled ice-ocean model to provide the first estimate of changes in the quantity of ice floating in the global oceans and the consequent sea level contribution.

Liquid Brine in Ice Shelves [PDF]
Journal of Glaciology, 1975 Holes drilled into thin areas of the Brunt Ice Shelf encounter a layer of liquid brine less than 1 m thick approximately at sea-level. Assuming the brine to be moving horizontally, analysis of its effects on thermal equilibrium gives an estimate of steady-state annual brine flow that is in good agreement with the value deduced from a percolation model.

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.

Automatic Extraction of the Calving Front of Pine Island Glacier Based on Neural Network
Remote Sensing, 2023 Calving front location plays a crucial role in studying ice–ocean interaction, mapping glacier area change, and constraining ice dynamic models. However, relying solely on visual interpretation to extract annual changes in the calving front of ice ...

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.

Estimation of ice shelf melt rate in the presence of a thermohaline staircase [PDF]
, 2015 Diffusive convection–favorable thermohaline staircases are observed directly beneath George VI Ice Shelf, Antarctica. A thermohaline staircase is one of the most pronounced manifestations of double-diffusive convection.

How the ocean melts Antarctic ice
Communications Earth & Environment, 2022 The floating ice shelves around Antarctica are key to buttressing land-based ice. Observations, simulations and analyses from around Antarctica now identify mechanisms that lead to basal melting of these vulnerable shelves.
