A simple stress-based cliff-calving law [PDF]

The Cryosphere, 2019
Over large coastal regions in Greenland and Antarctica the ice sheet calves directly into the ocean. In contrast to ice-shelf calving, an increase in calving from grounded glaciers contributes directly to sea-level rise.

Calving rates at tidewater glaciers vary strongly with ocean temperature [PDF]

, 2015
TerraSAR-X data were provided by DLR (project OCE1503), and funded by the Conoco Phillips-Lundin Northern Area Program through the CRIOS project (Calving Rates and Impact on Sea level). A.L. and S.B.

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.

Modelling calving front dynamics using a level-set method: application to Jakobshavn Isbræ, West Greenland [PDF]

The Cryosphere, 2016
Calving is a major mechanism of ice discharge of the Antarctic and Greenland ice sheets, and a change in calving front position affects the entire stress regime of marine terminating glaciers.

Stabilizing effect of mélange buttressing on the marine ice-cliff instability of the West Antarctic Ice Sheet [PDF]

The Cryosphere, 2022
Owing to global warming and particularly high regional ocean warming, both Thwaites and Pine Island Glaciers in the Amundsen region of the Antarctic Ice Sheet could lose their buttressing ice shelves over time.

A simple parametrization of mélange buttressing for calving glaciers [PDF]

The Cryosphere, 2021
Both ice sheets in Greenland and Antarctica are discharging ice into the ocean. In many regions along the coast of the ice sheets, the icebergs calve into a bay.

Halley Research Station, Antarctica: calving risks and monitoring strategies [PDF]

Natural Hazards and Earth System Sciences, 2014
The British Antarctic Survey's Halley Research Station is located on the Brunt Ice Shelf, Antarctica, where it is potentially vulnerable to calving events.

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]

, 2007
A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...

Melt-under-cutting and buoyancy-driven calving from tidewater glaciers: new insights from discrete element and continuum model simulations

Journal of Glaciology, 2017
The simple calving laws currently used in ice-sheet models do not adequately reflect the complexity and diversity of calving processes. To be effective, calving laws must be grounded in a sound understanding of how calving actually works.

Large spatial variations in the flux balance along the front of a Greenland tidewater glacier [PDF]

The Cryosphere, 2019
The frontal flux balance of a medium-sized tidewater glacier in western Greenland in the summer is assessed by quantifying the individual components (ice flux, retreat, calving, and submarine melting) through a combination of data and models. Ice flux
