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.

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 ...

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.

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.

Distinguishing subaerial and submarine calving with underwater noise
Journal of Glaciology, 2022 Iceberg calving is one of the major mechanisms of ice loss from tidewater glaciers and ice sheets, but obtaining accurate estimates of ice discharge that are both continuous and accurate is a challenging task.

Monitoring Greenland ice sheet buoyancy-driven calving discharge using glacial earthquakes
Annals of Glaciology, 2019 Since the 2000s, Greenland ice sheet mass loss has been accelerating, followed by increasing numbers of glacial earthquakes (GEs) at near-grounded glaciers. GEs are caused by calving of km-scale icebergs which capsize against the terminus. Seismic record

Journal of Glaciology, 2023 A major consideration for maritime activity in the Southern Hemisphere is the northern limit of icebergs, or the Southern Ocean Limit Of Known Ice (SOLOKI).

Iceberg properties and distributions in three Greenlandic fjords using satellite imagery
Annals of Glaciology, 2017 Icebergs calved from tidewater glaciers represent about one third to one half of the freshwater flux from the Greenland ice sheet to the surrounding ocean. Using multiple satellite datasets, we quantify the first fjord-wide distributions of iceberg sizes

Frontiers in Earth Science, 2020 Projections of future ice sheet mass loss and thus sea level rise rely on the parametrization of iceberg calving in ice sheet models. The interconnection between submarine melt-induced undercutting and calving is still poorly understood, which makes ...
