Ocean processes at the Antarctic continental slope [PDF]
, 2014 The Antarctic continental shelves and slopes occupy relatively small areas, but, nevertheless, are important for global climate, biogeochemical cycling and ecosystem functioning.

Quaternary sediment patterns in the Weddell Sea: relations and environmental conditions [PDF]
, 1988 Sediment patterns such as texture, composition, and facies from three selected areas of the Antarctic continental margin of the Weddell Sea are discussed in relation to environmental variations of the Quaternary hydrosphere and kryosphere.

Modeling ice shelf cavities in a z coordinate ocean general circulation model [PDF]
, 2008 . Processes at the ice shelf-ocean interface and in particular in ice shelf cavities around Antarctica have an observable effect on the solutions of basin scale to global coupled ice-ocean models.

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.

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.

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 ...

Mathematical Models of Ice Shelves [PDF]
Journal of Glaciology, 1976 For flat external ice shelves, expanding freely in all directions, the problem of thermodynamics is one-dimensional. In the affine dimensionless system of coordinates, equations of the dynamics together with the rheological equation lead to the non-linear integro-differential equation involving the reduced temperature.

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.

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.
