Antarctic calving loss rivals ice-shelf thinning

open access: yesNature, 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 fluxes and basal melt rates of Antarctic ice shelves

open access: yesNature, 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.

Calving prediction from ice mélange motion

open access: yesNature 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.

Cover: The calving event of the Drygalski Ice Tongue of February 2005

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.
