Calving glaciers and ice shelves [PDF]
Advances in Physics: X, 2018 Calving, or the release of icebergs from glaciers and floating ice shelves, is an important process transferring mass into the world’s oceans. Calving glaciers and ice sheets make a large contribution to sea-level rise, but large uncertainty remains ...

Evaluation of four calving laws for Antarctic ice shelves [PDF]
The Cryosphere, 2023 Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve icebergs and how fast they flow determine whether they advance, retreat, or ...

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.

Ocean tides trigger ice shelf rift growth and calving. [PDF]
Nat CommunAbstract Tabular iceberg calving reduces ice-shelf extent, affecting ocean circulation and ice-sheet stability. Here we present detailed observations of a rift on the Brunt Ice Shelf, East Antarctica, from 2017-2023 and its behaviour in the lead up to calving in January 2023. The timing of rift propagation was controlled by the rate of change

The Influence of Pine Island Ice Shelf Calving on Basal Melting
Journal of Geophysical Research: Oceans, 2022 AbstractThe combination of the Pine Island Ice Shelf (PIIS) draft and a seabed ridge beneath it form a topographic barrier, restricting access of warm Circumpolar Deep Water to a cavity inshore of the ridge, thus exerting an important control on PIIS basal ablation.

Atmospheric Triggers of the Brunt Ice Shelf Calving in February 2021
Journal of Geophysical Research D: Atmospheres, 2022 AbstractThe calving of Antarctic ice shelves remains unpredictable to date due to a lack of understanding of the role of the different climatic components in such events. In this study, the role of atmospheric forcing in the calving of the Brunt Ice Shelf (BIS) in February 2021 is investigated using a combination of observational and reanalysis data ...

The instantaneous impact of calving and thinning on the Larsen C Ice Shelf [PDF]
The Cryosphere, 2022 The Antarctic Peninsula has seen rapid and widespread changes in the extent of its ice shelves in recent decades, including the collapse of the Larsen A and B ice shelves in 1995 and 2002, respectively.

The integrated ice sheet response to stochastic iceberg calving
Journal of GlaciologyIceberg calving is a major source of ice loss from the Antarctic and Greenland ice sheets. However, it is still one of the most poorly understood aspects of ice sheet dynamics, in part due to its variability at a wide range of spatial and temporal scales.

A 15-year circum-Antarctic iceberg calving dataset derived from continuous satellite observations [PDF]
Earth System Science Data, 2021 Iceberg calving is the main process that facilitates the dynamic mass loss of ice sheets into the ocean, which accounts for approximately half of the mass loss of the Antarctic ice sheet.

The speedup of Pine Island Ice Shelf between 2017 and 2020: revaluating the importance of ice damage
Journal of Glaciology, 2023 From 2017 to 2020, three significant calving events took place on Pine Island Glacier, West Antarctica. Ice-shelf velocities changed over this period and the calving events have been suggested as possible drivers.
