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.

Ice shelf calving due to shear stresses: observing the response of Brunt Ice Shelf and Halloween Crack to iceberg calving using ICESat-2 laser altimetry, satellite imagery, and ice flow models [PDF]
The CryosphereFull-thickness ice shelf fractures, known as rifts, create tabular icebergs that can reduce ice shelf extent and thereby jeopardize overall marine ice sheet stability.

'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 ...

Quasi-static granular flow of ice mélange [PDF]
, 1936 We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier.

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.

Calving Seasonality Associated With Melt‐Undercutting and Lake Ice Cover [PDF]
Geophysical Research Letters, 2020 AbstractA detailed understanding of calving processes at the lacustrine margins of the Greenland ice sheet is necessary for accurately forecasting its dynamic response to ongoing climate change. However, existing data sets of lacustrine calving are limited to summer seasons and to alpine glaciers.

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.

Annals of Glaciology, 1989 Calving ice walls are an important ablation mechanism for deglaciation of calving bays occupied by temperate tide-water glaciers and polar marine ice sheets. Dangers inherent in calving bays have precluded detailed field studies of these calving ice walls.

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
