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.

Formation of sea ice ponds from ice-shelf runoff, adjacent to the McMurdo Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 2020 Ponds that form on sea ice can cause it to thin or break-up, which can promote calving from an adjacent ice shelf. Studies of sea ice ponds have predominantly focused on Arctic ponds formed by in situ melting/ponding.

Past and future dynamics of the Brunt Ice Shelf from seabed bathymetry and ice shelf geometry [PDF]
The Cryosphere, 2019 The recent rapid growth of rifts in the Brunt Ice Shelf appears to signal the onset of its largest calving event since records began in 1915. The aim of this study is to determine whether this calving event will lead to a new steady state in which the ...

Measurements of Ice Shelf Water beneath the front of the Ross Ice Shelf using gliders [PDF]
Annals of Glaciology, 2017 Measurements made by an underwater glider deployed near the Ross Ice Shelf were used to identify the presence of Ice Shelf Water (ISW), which is defined as seawater with its potential temperature lower than its surface freezing point temperature ...

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.

Marine ice in Larsen Ice Shelf [PDF]
Geophysical Research Letters, 2009 It is argued that Larsen Ice Shelf contains marine ice formed by oceanic freezing and other mechanisms. Missing basal returns in airborne radar soundings and observations of a smooth and healed surface coincide downstream of regions where an ocean model predicts freezing.

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 ...

The distribution and evolution of surface fractures on pan-Antarctic ice shelves
International Journal of Digital Earth, 2023 Surface fractures have a great impact on ice shelf stability in Antarctica and can be considered precursors of ice shelf calving. However, our understanding of the spatial distribution and temporal evolution of surface fractures on the Antarctic 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.

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 ...
