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 ...

Melt-under-cutting and buoyancy-driven calving from tidewater glaciers: new insights from discrete element and continuum model simulations [PDF]
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.

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 ...

Thinning sea ice weakens buttressing force of iceberg mélange and promotes calving [PDF]
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 ...

Velocity response of Petermann Glacier, northwest Greenland, to past and future calving events [PDF]
The Cryosphere, 2018 Dynamic ice discharge from outlet glaciers across the Greenland Ice Sheet has increased since the beginning of the 21st century. Calving from floating ice tongues that buttress these outlets can accelerate ice flow and discharge of grounded ice. However,

Halley Research Station, Antarctica: calving risks and monitoring strategies [PDF]
Natural Hazards and Earth System Sciences, 2014 The British Antarctic Survey's Halley Research Station is located on the Brunt Ice Shelf, Antarctica, where it is potentially vulnerable to calving events.

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 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.
