Modeling ice shelf/ocean interaction in Antarctica: A review

MS Dinniman, XS Asay-Davis, BK Galton-Fenzi… - Oceanography, 2016 - JSTOR
The most rapid loss of ice from the Antarctic Ice Sheet is observed where ice streams flow
into the ocean and begin to float, forming the great Antarctic ice shelves that surround much …

Calving fluxes and basal melt rates of Antarctic ice shelves

MA Depoorter, JL Bamber, JA Griggs, JTM Lenaerts… - Nature, 2013 - nature.com
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 …

Ice-shelf melting around Antarctica

E Rignot, S Jacobs, J Mouginot, B Scheuchl - Science, 2013 - science.org
We compare the volume flux divergence of Antarctic ice shelves in 2007 and 2008 with 1979
to 2010 surface accumulation and 2003 to 2008 thinning to determine their rates of melting …

Ocean-driven thinning enhances iceberg calving and retreat of Antarctic ice shelves

Y Liu, JC Moore, X Cheng… - Proceedings of the …, 2015 - National Acad Sciences
Iceberg calving from all Antarctic ice shelves has never been directly measured, despite
playing a crucial role in ice sheet mass balance. Rapid changes to iceberg calving naturally …

Direct observations of melting, freezing, and ocean circulation in an ice shelf basal crevasse

P Washam, JD Lawrence, CL Stevens, CL Hulbe… - Science …, 2023 - science.org
Ocean conditions near the grounding zones of Antarctica's ice shelves play a key role in

Overview of areal changes of the ice shelves on the Antarctic Peninsula over the past 50 years

AJ Cook, DG Vaughan - The cryosphere, 2010 - tc.copernicus.org
In recent decades, seven out of twelve ice shelves around the Antarctic Peninsula (AP) have
either retreated significantly or have been almost entirely lost. At least some of these retreats …

Melt rates in the kilometer-size grounding zone of Petermann Glacier, Greenland, before and during a retreat

E Ciracì, E Rignot, B Scheuchl… - Proceedings of the …, 2023 - National Acad Sciences
Warming of the ocean waters surrounding Greenland plays a major role in driving glacier
retreat and the contribution of glaciers to sea level rise. The melt rate at the junction of the …

Ocean tide influences on the Antarctic and Greenland ice sheets

L Padman, MR Siegfried, HA Fricker - Reviews of Geophysics, 2018 - Wiley Online Library
Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …
