The effect of landfast sea ice buttressing on ice dynamic speedup in the Larsen B embayment, Antarctica [PDF]
The CryosphereWe observe the evacuation of 11-year-old landfast sea ice in the Larsen B embayment on the East Antarctic Peninsula in January 2022, which was in part triggered by warm atmospheric conditions and strong offshore winds.

Basal crevasses in Larsen C Ice Shelf and implications for their global abundance [PDF]
The Cryosphere, 2012 Basal crevasses extend upwards from the base of ice bodies and can penetrate more than halfway through the ice column under conditions found commonly on ice shelves.

Three-dimensional modelling of calving processes on Johnsons Glacier, Livingston Island, Antarctica. [PDF]
, 2010 Iceberg calving is an important mass loss mechanism from ice shelves and tidewater glaciers for many mid and high-latitude glaciers and ice caps, yet the process is not well represented in prognostic models of ice dynamics.

Seasonal variability of ocean heat transport and ice-shelf basal melt around Antarctica [PDF]
The CryosphereThe delivery of ocean heat to Antarctic ice shelves is due to intrusions of waters warmer than the local freezing point temperature. Changes in the supply of ocean heat will determine how rapidly ice shelves melt at their base, which affects Antarctic ...

Regime of the Filchner-Ronne Ice Shelves, Antarctica
, 1983 Seismic, radio-echo, TWERLE balloon and oceanographic data of the Filchner-Ronne ice shelves are analysed. A large thin area in the central Ronne Ice Shelf is found to differ from the morphology of the Ross and Filchner ice shelves.

Evaluating CMIP6 models for near-surface air temperature projections over Antarctic ice shelves
Journal of GlaciologyThe meltwater-driven disintegration of the Larsen B ice shelf has raised concerns that other ice shelves may face similar vulnerabilities as global temperatures rise.

Ice viscosity is more sensitive to stress than commonly assumed
Communications Earth & Environment, 2022 The rate of deformation in Antarctic ice shelves is proportional to stress to the power of 4, not 3 as often used in models, according to a calibration of Glen’s Flow Law with satellite remote sensing data from Antarctic ice shelves.

A phase field model for fractures in ice shelves [PDF]
, 2022 Ice shelves are large floating ice masses, that are formed when glaciers are becoming afloat at the margin of ice sheets. One dominating mass loss mechanism of ice shelves is calving, describing the detachment of icebergs at the front.

Simulated melt rates for the Totten and Dalton ice shelves [PDF]
Ocean Science, 2014 The Totten Glacier is rapidly losing mass. It has been suggested that this mass loss is driven by changes in oceanic forcing; however, the details of the ice–ocean interaction are unknown.

The safety band of Antarctic ice shelves
, 2016 International audienceThe floating ice shelves along the seaboard of the Antarctic ice sheet restrain the outflow of upstream grounded ice. Removal of these ice shelves, as shown by past ice-shelf recession and break-up, accelerates the outflow, which ...
