Antarctic calving loss rivals ice-shelf thinning

Nature, 2022
Antarctica's ice shelves help to control the flow of glacial ice as it drains into the ocean, meaning that the rate of global sea-level rise is subject to the structural integrity of these fragile, floating extensions of the ice sheet1-3. Until now, data limitations have made it difficult to monitor the growth and retreat cycles of ice shelves on a ...

Calving prediction from ice mélange motion

Nature Geoscience, 2021
High-frequency radar tracking of icebergs floating in front of a glacier in Greenland show that movements of the ice melange consistently increase before calving events, indicating that melange has the potential to modulate calving.

A Simple Law for Ice-Shelf Calving

Science, 2008
A major problem for ice-sheet models is that no physically based law for the calving process has been established. Comparison across a diverse set of ice shelves demonstrates that iceberg calving increases with the along-flow spreading rate of a shelf.

Modelling calving at Kronebreen, Svalbard using Elmer/Ice

2021
<p>Understanding how tidewater glaciers are responding to climatic and oceanographic changes is vital in order to reduce uncertainty in sea level rise estimates. In this project, we are using the 3D calving model in Elmer/Ice to simulate how Kronebreen responds over short time scales to various forcing scenarios.

Ice-Age Simulations with a Calving Ice-Sheet Model

Quaternary Research, 1983
AbstractVariations of ice-sheet volume during the Quaternary ice ages are simulated using a simple ice-sheet model for the Northern Hemisphere. The basic model predicts ice thickness and bedrock deformation in a north-south cross section, with a prescribed snow-budget distribution shifted uniformly in space to represent the orbital perturbations.

Calving fluxes and basal melt rates of Antarctic ice shelves

Nature, 2013
Iceberg calving has been assumed to be the dominant cause of mass loss for the Antarctic ice sheet, with previous estimates of the calving flux exceeding 2,000 gigatonnes per year. More recently, the importance of melting by the ocean has been demonstrated close to the grounding line and near the calving front.
