A Simple Law for Ice-Shelf Calving
Science, 2008A 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.

Cover: The calving event of the Drygalski Ice Tongue of February 2005 [PDF]
International Journal of Remote Sensing, 2005 The Drygalski Ice Tongue (DIT) is the seaward extension of David Glacier, the largest outlet glacier in Victoria Land, east Antarctica. DIT marks the southern border of Terra Nova Bay and plays a decisive role in the development of Terra Nova Bay polynya. A sketch map of the area around Terra Nova Bay is shown in figure 1.

The calving constraints on inception of Quaternary ice sheets
Quaternary International, 2002Abstract Most numerical models that simulate the inception of Quaternary ice sheets nucleate the ice sheets in high-latitude highlands of the Northern Hemisphere. These nuclei are initially plateau or island ice caps that then expand and merge with one another to become an ice sheet. Before merger, however, these ice caps often must cross continental

Ice-Age Simulations with a Calving Ice-Sheet Model
Quaternary Research, 1983AbstractVariations 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.

Impacts of the Larsen-C Ice Shelf calving event
Nature Climate Change, 2017A giant iceberg has calved off the Larsen-C Ice Shelf, the largest remaining ice shelf on the Antarctic Peninsula, reducing its total area by ~10%. Whilst calving events are a natural phenomenon and thus not necessarily indicative of changing environmental conditions, such events can impact ice-shelf stability.

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.

The source and calving of ice island ARLIS-II
Polar Record, 1992AbstractOn the basis of existing data on the dimensions, shape, surficial geology, and glaciological structure of ice island ARLIS-II, used in combination with aerial photographs of northernmost Ellesmere Island taken in 1950 and 1959, the source of the ice island is positively identified as the Alfred Ernest Ice Shelf. The duration of the recent drift

On the recent calving of icebergs from the Ross ice shelf
Polar Geography, 2008Abstract The year 2000 has witnessed the calving of several remarkably large icebergs in the Ross and Weddell seas of Antarctica, including the calving of B-l 5, possibly the largest iceberg yet to be observed. Here we present satellite imagery that records the calving, and precursor events leading up to the detachment of B-l 5 from the Ross Ice Shelf ...

Size distributions of small ice pieces calved from icebergs
Cold Regions Science and Technology, 2000Abstract This study was part of a larger project currently underway to develop an operational iceberg drift and deterioration model for the Canadian Ice Service (CIS), Environment Canada. This new iceberg model, as distinct from previous drift computations, will include estimates of iceberg calving and production of smaller ice pieces in the bergy ...

Some Ice-Age Aspects of a Calving Ice-Sheet Model
1984Further results and extensions of a simple northern hemispheric ice-sheet model are described for the Quaternary ice ages. The model predicts ice thickness and bedrock deformation in a north-south cross section, with a prescribed snow-budget distribution shifted vertically to represent the orbital pertur-bations.
