Calving Fronts of Antarctica: Mapping and Classification

Remote Sensing, 2013
Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1

Predicting the steady-state isochronal stratigraphy of ice shelves using observations and modeling [PDF]

The Cryosphere, 2022
Ice shelves surrounding the Antarctic perimeter moderate ice discharge towards the ocean through buttressing. Ice-shelf evolution and integrity depend on the local surface accumulation, basal melting and on the spatially variable ice-shelf viscosity ...

The Creep of Ice Shelves Theory [PDF]

Journal of Glaciology, 1973
AbstractBudd’s expressions for strain-rate gradient along the centre line of a bounded ice shelf are shown to be applicable only to ice shelves with almost constant thickness and very small longitudinal strain-rates. A general expression is derived for creep in an ice shelf where the sole restriction is that of zero shear stresses in vertical planes ...

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics [PDF]

, 2010
We present results from numerical ice-flow models that include calving criteria based on penetration of surface and basal crevasses, which in turn is a function of longitudinal strain rates near the glacier front.

Comparing calving laws at Greenland's three largest ice shelves [PDF]

The Cryosphere
The retreat of Greenlandic glaciers through calving has major implications for the ice sheet's mass balance and future sea-level rise contributions. Despite its importance, the implementation of calving in ice sheet models remains contested, with several

An assessment of basal melting parameterisations for Antarctic ice shelves

The Cryosphere, 2021
Ocean-induced melting at the base of ice shelves is one of the main drivers of the currently observed mass loss of the Antarctic Ice Sheet. A good understanding of the interaction between ice and ocean at the base of the ice shelves is therefore crucial ...

Frazil dynamics and precipitation in a water column with depth-dependent supercooling [PDF]

, 2005
When seawater becomes supercooled, collections of small ice crystals, known as frazil ice, form and grow. A model of frazil ice dynamics is presented that deals explicitly with the buoyant settling of frazil crystals onto an overlying surface.

Getting around Antarctica: new high-resolution mappings of the grounded and freely-floating boundaries of the Antarctic ice sheet created for the International Polar Year [PDF]

, 2011
The boundary of grounded ice and the location of ice transitioning to a freely floating state are mapped at 15-m resolution around the entire continent of Antarctica.
