Calving cycle of Ninnis Glacier over the last 60 years
International Journal of Applied Earth Observations and Geoinformation, 2021 Iceberg calving is one of the contributing ways for the mass loss from ice shelves in Antarctica; the calving cycles of most ice shelves are quite long.

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.

Surveying a Floating Iceberg With the USV SEADRAGON
Frontiers in Marine Science, 2021 The calving, drifting, and melting of icebergs has local, regional, and global implications. Besides the impacts to local ecosystems due to changes in seawater salinity and temperature, the freshwater influx and transport can have significant regional ...

Processes of crevasse formation and the dynamics of calving glaciers : a study at Breiđamerkurjökull [PDF]
, 2009 A new model proposed by Benn et al. (2006, 2007) explains the dynamics of calving glaciers based on a new sliding law and a calving criterion modified from a crevasse depth model. In this thesis three key elements of this model are tested: 1) the role

Thinning sea ice weakens buttressing force of iceberg mélange and promotes calving
Nature Communications, 2017 Observed sea-ice loss near ice sheets has, in many cases, been accompanied by accelerated iceberg calving. Here, using a new model, the authors show that iceberg calving from glaciers can be suppressed by a mélange of sea ice and icebergs, with an ...

Semi-automated open water iceberg detection from Landsat applied to Disko Bay, West Greenland
Journal of Glaciology, 2019 Changes in Greenland's marine-terminating outlet glaciers have led to changes in the flux of icebergs into Greenland's coastal waters, yet icebergs remain a relatively understudied component of the ice-ocean system.

Viscous and elastic buoyancy stresses as drivers of ice-shelf calving
Journal of Glaciology, 2020 The Antarctic Ice Sheet loses mass via its ice shelves predominantly through two processes: basal melting and iceberg calving. Iceberg calving is episodic and infrequent, and not well parameterized in ice-sheet models.

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.

Observational constraints on the sensitivity of two calving glaciers to external forcings
Journal of Glaciology, 2023 Future mass loss projections of the Greenland ice sheet require understanding of the processes at a glacier terminus, especially of iceberg calving.
