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.

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

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 ...

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.

Speed-up, slowdown, and redirection of ice flow on neighbouring ice streams in the Pope, Smith, and Kohler region of West Antarctica [PDF]
The CryosphereThe ice streams feeding the Dotson and Crosson ice shelves are some of the fastest changing in West Antarctica. We use satellite observations to measure the change in ice speed and flow direction on eight ice streams in the Pope, Smith, and Kohler region

Simulating ice-shelf extent using damage mechanics
Journal of Glaciology, 2022 Inaccurate representations of iceberg calving from ice shelves are a large source of uncertainty in mass-loss projections from the Antarctic ice sheet. Here, we address this limitation by implementing and testing a continuum damage-mechanics model in a ...

Tidal bending of ice shelves as a mechanism for large-scale temporal variations in ice flow [PDF]
, 2018 GPS measurements reveal strong modulation of horizontal ice shelf and ice stream flow at a variety of tidal frequencies, most notably a fortnightly (Msf) frequency not present in the vertical tides themselves. Current theories largely fail to explain the

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.

Treatment of the ice-shelf backpressure and buttressing in two horizontal dimensions
Journal of GlaciologyThe ice discharge from the grounded parts of marine ice sheets into the ocean is modulated by their floating extensions – ice shelves. The ice-shelf impact on the grounded ice is typically described as ‘backpressure’ or ‘buttressing’.
