Can rifts alter ocean dynamics beneath ice shelves? [PDF]
The Cryosphere, 2023 Land ice discharge from the Antarctic continent into the ocean is restrained by ice shelves, floating extensions of grounded ice that buttress the glacier outflow.

Explicit representation and parametrised impacts of under ice shelf seas in the z∗ coordinate ocean model NEMO 3.6 [PDF]
Geoscientific Model Development, 2017 Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Abatement of Ocean-Wave Impact by Crevasses in an Ice Shelf
Journal of Marine Science and Engineering, 2021 Forced ice-shelf oscillations modeling was undertaken employing a full 3D finite-difference model of an elastic ice shelf that was coupled to a treatment of under-shelf seawater flux.

Ice-shelf damming in the glacial Arctic Ocean: dynamical regimes of a basin-covering kilometre-thick ice shelf [PDF]
The Cryosphere, 2017 Recent geological and geophysical data suggest that a 1 km thick ice shelf extended over the glacial Arctic Ocean during Marine Isotope Stage 6, about 140 000 years ago.

Time-Dependent Modelling of the Wave-Induced Vibration of Ice Shelves
Journal of Marine Science and Engineering, 2023 This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused on the effect of changes in the draft on the vibration of the ice shelf and presents both time-domain and frequency-domain ...

Environmental Research Letters, 2021 Recent observations indicate that two cryospheric components, namely the Antarctic sea ice and ice shelf over the Southern Ocean, have been changing over the decades. Here we analyze results from an ocean–sea ice–ice shelf model to examine variability in

Southern Weddell Sea surface freshwater flux modulated by icescape and atmospheric forcing [PDF]
Ocean Science, 2023 Sea ice formation dominates surface salt forcing in the southern Weddell Sea. Brine rejected in the process of sea ice production results in the production of High Salinity Shelf Water (HSSW) that feeds the global overturning circulation and fuels the ...

Modeling ice‐ocean interaction in ice‐shelf crevasses [PDF]
Journal of Geophysical Research: Oceans, 2014 AbstractOcean freezing within ice‐shelf basal crevasses could potentially act as a stabilizing influence on ice shelves; however, ice‐ocean interaction and ocean dynamics within these crevasses are as yet poorly understood. To this end, an idealized 2‐D model of an ice‐shelf basal crevasse has been developed using Fluidity, a finite‐element ocean model

Ice-Ocean Interaction On Ronne Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 1990 A detailed glaciological study of Ronne Ice Shelf has been undertaken along a flowline extending from Rutford Ice Stream grounding line to the ice front. Measurements of velocity, surface elevation, ice thickness, surface temperature and accumulation rate have been made at a total of 28 sites; at 17 of these ice deformation rates are also known ...

An ice-shelf model test based on the Ross Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 1996 A standard numerical experiment featuring the Ross Ice Shelf, Antarctica, is presented as a test package for the development and intercomparison of ice-shelf models. The emphasis of this package is solution of stress-equilibrium equations for an ice-shelf velocity consistent with present observations.
