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 ...

Rapid fragmentation of Thwaites Eastern Ice Shelf [PDF]
The Cryosphere, 2022 Ice shelves play a key role in the dynamics of marine ice sheets by buttressing grounded ice and limiting rates of ice flux to the oceans. In response to recent climatic and oceanic change, ice shelves fringing the West Antarctic Ice Sheet (WAIS) have ...

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 ...

Journal of Advances in Modeling Earth Systems, 2022 The processes responsible for freshwater flux from the Antarctic Ice Sheet (AIS), ice‐shelf basal melting and iceberg calving, are generally poorly represented in current Earth System Models (ESMs).

Calving cycle of the Brunt Ice Shelf, Antarctica, driven by changes in ice-shelf geometry [PDF]
The Cryosphere, 2019 Abstract. Despite the potentially detrimental impact of large-scale calving events on the geometry and ice flow of the Antarctic Ice Sheet, little is known about the processes that drive rift formation prior to calving, or what controls the timing of these events.

Energetics of Eddy-Mean Flow Interactions in the Amery Ice Shelf Cavity
Frontiers in Marine Science, 2021 Previous studies demonstrated that eddy processes play an important role in ice shelf basal melting and the water mass properties of ice shelf cavities.

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 ...

Dynamics of the Ross Ice Shelf
Eos, Transactions American Geophysical Union, 1991 The Ross Ice Shelf and the Ross Sea have been examined as part of the study of Antarctic coastal cyclones conducted at the Byrd Polar Research Center [Bromwich, 1991], using Advanced Very High Resolution Radiometer (AVHRR) data at 1.1‐km resolution. Several glaciological features appear clearly on the images (Figure 1).

Frazil ice formation in an ice shelf water plume [PDF]
Journal of Geophysical Research: Oceans, 2004 We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow of buoyant water upward along the ice shelf base and includes the differential growth of a range of crystal sizes.

Getz Ice Shelf melt enhanced by freshwater discharge from beneath the West Antarctic Ice Sheet [PDF]
The Cryosphere, 2020 Antarctica's Getz Ice Shelf has been rapidly thinning in recent years, producing more meltwater than any other ice shelf in the world. The influx of fresh water is known to substantially influence ocean circulation and biological productivity, but ...
