Calving processes at a grounded ice cliff [PDF]
Annals of Glaciology, 1997 Repeat photographs and field survey reveal the mechanism of short-term ice-cliff evolution at Maud Glacier, a temperate lake-calving glacier in New Zealand. Calving is cyclic, each cycle involving four stages: (1) waterline melting and collapse of the roof of a sub-horizontal notch at the cliff foot; (2) calving of ice flakes from the cliff face ...

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.

Bathymetric controls on calving processes at Pine Island Glacier [PDF]
The Cryosphere, 2018 Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. Its ice loss has substantially increased over the last 25 years through thinning, acceleration and grounding line retreat.

Thinning leads to calving-style changes at Bowdoin Glacier, Greenland [PDF]
The Cryosphere, 2021 Ice mass loss from the Greenland ice sheet is the largest single contributor to sea level rise in the 21st century. The mass loss rate has accelerated in recent decades mainly due to thinning and retreat of its outlet glaciers.

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.

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.

On Mathews Correlation Coefficient and Improved Distance Map Loss for Automatic Glacier Calving Front Segmentation in SAR Imagery [PDF]
, 2021 The vast majority of the outlet glaciers and ice streams of the polar ice sheets end in the ocean. Ice mass loss via calving of the glaciers into the ocean has increased over the last few decades. Information on the temporal variability of the calving front position provides fundamental information on the state of the glacier and ice stream, which can ...

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.

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

'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 ...
