The statistical physics of iceberg calving and the emergence of universal calving laws [PDF]
Journal of Glaciology, 2011 AbstractDetermining a calving law valid for all glaciological and environmental regimes has proven to be a difficult problem in glaciology. For this reason, most models of the calving process are semi-empirical, with little connection to the underlying fracture processes.

Calving of large tabular icebergs from ice shelf rift systems [PDF]
Geophysical Research Letters, 2005 We used Interferometric Synthetic Aperture Radar to study the detachment process that allowed two large icebergs to calve from the Ross Ice Shelf, Antarctica. Time series of rift geometries indicate that rift widths increased steadily, whereas rift lengths increased episodically through several discrete rift‐tip propagation events.

A Transient Coupled Ice Flow‐Damage Model to Simulate Iceberg Calving From Tidewater Outlet Glaciers
Journal of Advances in Modeling Earth Systems, 2019 Iceberg calving, the detachment of an ice block at the glacier front, is the main process responsible for the dynamic mass loss from the ice sheets to the ocean.

The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain
Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]
, 2013 We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

'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 ...

NEMO-ICB (v1.0): interactive icebergs in the NEMO ocean model globally configured at eddy-permitting resolution [PDF]
, 2015 An established iceberg module, ICB, is used interactively with the Nucleus for European Modelling of the Ocean (NEMO) ocean model in a new implementation, NEMO–ICB (v1.0).

Antarctic Meltwater‐Stratification Feedback Is Less Pronounced Under High Climate Forcing
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Several studies have shown sub‐surface warming in the Southern Ocean via an increase in meltwater flux from the Antarctic Ice Sheet (AIS), which can lead to a positive feedback through enhanced basal melting. In this study, we investigate how the feedback strength is related to the prevailing climate in a coupled climate–ice‐sheet model.
