Winter thermohaline evolution along and below the Ross Ice Shelf [PDF]
Nature CommunicationsThe Ross Ice Shelf floats above the southern sector of the Ross Sea and creates a cavity where critical ocean-ice interactions take place. Crucial processes occurring in this cavity include the formation of Ice Shelf Water, the coldest ocean water, and ...

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 ...

Ice Shelf Water plume flow beneath Filchner‐Ronne Ice Shelf, Antarctica [PDF]
Journal of Geophysical Research: Oceans, 2007 A two‐dimensional plume model is used to study the interaction between Filchner‐Ronne Ice Shelf, Antarctica and its underlying ocean cavity. Ice Shelf Water (ISW) plumes are initiated by the freshwater released from a melting ice shelf and, if they rise, may become supercooled and deposit marine ice due to the pressure increase in the in situ freezing ...

The internal structure of the Brunt Ice Shelf from ice-penetrating radar analysis and implications for ice shelf fracture [PDF]
The Cryosphere, 2018 The rate and direction of rift propagation through ice shelves depend on both the stress field and the heterogeneity (or otherwise) of the physical properties of the ice.

The complex basal morphology and ice dynamics of the Nansen Ice Shelf, East Antarctica [PDF]
The CryosphereIce shelf dynamics and morphology play an important role in the stability of floating bodies of ice by driving fracturing that can lead to calving, in turn impacting the ability of the ice shelf to buttress upstream grounded ice. Following a 2016 calving

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.
