Multidecadal warming of Antarctic waters [PDF]
, 2014 Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice

Exploring mechanisms responsible for tidal modulation in flow of the Filchner–Ronne Ice Shelf [PDF]
, 2020 An extensive network of GPS sites on the Filchner–Ronne Ice Shelf and adjoining ice streams shows strong tidal modulation of horizontal ice flow at a range of frequencies.

Response of Pacific-sector Antarctic ice shelves to the El Niño/Southern Oscillation. [PDF]
, 2018 Satellite observations over the past two decades have revealed increasing loss of grounded ice in West Antarctica, associated with floating ice shelves that have been thinning.

Response to Filchner–Ronne Ice Shelf cavity warming in a coupled ocean–ice sheet model – Part 1: The ocean perspective [PDF]
Ocean Science, 2017 The Regional Antarctic ice and Global Ocean (RAnGO) model has been developed to study the interaction between the world ocean and the Antarctic ice sheet. The coupled model is based on a global implementation of the Finite Element Sea-ice Ocean Model (

Modelling the influence of marine ice on the dynamics of an idealised ice shelf
Journal of Glaciology, 2023 Understanding the dynamic behaviour of ice shelves, specifically the controls on their ability to buttress the flow of ice into the ocean, is critical for predicting future ice-sheet contributions to sea level rise.

Lateral meltwater transfer across an Antarctic ice shelf
The Cryosphere, 2020 . Surface meltwater on ice shelves can exist as slush, it can pond in lakes or crevasses, or it can flow in surface streams and rivers. The collapse of the Larsen B Ice Shelf in 2002 has been attributed to the sudden drainage of ∼3000 surface lakes and ...

Evolution of Supraglacial Lakes on the Larsen B Ice Shelf in the Decades Before it Collapsed
Geophysical Research Letters, 2020 The Larsen B ice shelf collapsed in 2002 losing an area twice the size of Greater London to the sea (3,000 km2), in an event associated with widespread supraglacial lake drainage.

Ice-shelf basal melting in a global finite-element sea-ice/ice-shelf/ocean model [PDF]
Annals of Glaciology, 2012 AbstractThe Finite Element Sea-ice Ocean Model (FESOM) has been augmented by an ice-shelf component with a three-equation system for diagnostic computation of boundary layer temperature and salinity. Ice-shelf geometry and global ocean bathymetry have been derived from the RTopo-1 dataset.

Ice‐Front Retreat Controls on Ocean Dynamics Under Larsen C Ice Shelf, Antarctica
Geophysical Research Letters, 2023 Iceberg A‐68 separated from the Larsen C Ice Shelf in July 2017 and the impact of this event on the local ocean circulation has yet to be assessed.

Seabed corrugations beneath an Antarctic ice shelf revealed by autonomous underwater vehicle survey: Origin and implications for the history of Pine Island Glacier [PDF]
, 2013 Ice shelves are critical features in the debate about West Antarctic ice sheet change and sea level rise, both because they limit ice discharge and because they are sensitive to change in the surrounding ocean.
