Two Calving Laws for Grounded Iceberg-Calving Glaciers (Abstract only) [PDF]
Annals of Glaciology, 1983 Prediction of the future retreat of Columbia Glacier, Alaska, required a calving law for the boundary condition at the terminus. Qualitative observations on the variations of all major iceberg-calving glaciers of Alaska suggest that calving is high whenever glaciers terminate in deep water, and greatly reduced whenever they ...

Large-scale experiments into the tsunamigenic potential of different iceberg calving mechanisms. [PDF]
Sci Rep, 2019 AbstractMass balance analysis of ice sheets is a key component to understand the effects of global warming. A significant component of ice sheet and shelf mass balance is iceberg calving, which can generate large tsunamis endangering human beings and coastal infrastructure.

Fragmentation theory reveals processes controlling iceberg size distributions [PDF]
Journal of Glaciology, 2021 Iceberg calving strongly controls glacier mass loss, but the fracture processes leading to iceberg formation are poorly understood due to the stochastic nature of calving.

A unifying framework for iceberg-calving models [PDF]
Journal of Glaciology, 2010 AbstractWe propose a general framework for iceberg-calving models that can be applied to any calving margin. The framework is based on mass continuity, the assumption that calving rate and terminus velocity are not independent and the simple idea that terminus thickness following a calving event is larger than terminus thickness at the event onset. The

Buoyant forces promote tidewater glacier iceberg calving through large basal stress concentrations [PDF]
The Cryosphere, 2019 Iceberg calving parameterisations currently implemented in ice sheet models do not reproduce the full observed range of calving behaviours. For example, though buoyant forces at the ice front are known to trigger full-depth calving events on major ...

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.

Quantifying iceberg calving fluxes with underwater noise [PDF]
The Cryosphere, 2020 Accurate estimates of calving fluxes are essential in understanding small-scale glacier dynamics and quantifying the contribution of marine-terminating glaciers to both eustatic sea-level rise (SLR) and the freshwater budget of polar regions.

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.

A Transient Coupled Ice Flow‐Damage Model to Simulate Iceberg Calving From Tidewater Outlet Glaciers [PDF]
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.
