Stability of Ice Shelves and Ice Cliffs in a Changing Climate
Annual Review of Earth and Planetary SciencesThe largest uncertainty in future sea-level rise is loss of ice from the Greenland and Antarctic Ice Sheets. Ice shelves, freely floating platforms of ice that fringe the ice sheets, play a crucial role in restraining discharge of grounded ice into the ocean through buttressing. However, since the 1990s, several ice shelves have thinned, retreated, and

Fracture Mechanical Analysis of Cracks in Ice Shelves using the Finite Element Method and Configurational Forces [PDF]
, 2011 Ice shelves are important elements of the climate system and sensitive to climate changes. The disintegration of large Antarctic ice shelves is the focus of this fracture mechanical analysis. Ice is a complex material which, depending on the context, can

Tidal bending of ice shelves as a mechanism for large-scale temporal variations in ice flow [PDF]
, 2018 GPS measurements reveal strong modulation of horizontal ice shelf and ice stream flow at a variety of tidal frequencies, most notably a fortnightly (Msf) frequency not present in the vertical tides themselves. Current theories largely fail to explain the

Change in Antarctic ice shelf area from 2009 to 2019 [PDF]
The Cryosphere, 2023 Antarctic ice shelves provide buttressing support to the ice sheet, stabilising the flow of grounded ice and its contribution to global sea levels. Over the past 50 years, satellite observations have shown ice shelves collapse, thin, and retreat; however,

Can rifts alter ocean dynamics beneath ice shelves? [PDF]
The Cryosphere, 2023 Land ice discharge from the Antarctic continent into the ocean is restrained by ice shelves, floating extensions of grounded ice that buttress the glacier outflow.

Ice-shelf ocean boundary layer dynamics from large-eddy simulations [PDF]
The Cryosphere, 2022 Small-scale turbulent flow below ice shelves is regionally isolated and difficult to measure and simulate. Yet these small-scale processes, which regulate heat and salt transfer between the ocean and ice shelves, can affect sea-level rise by altering ...

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.

Variable temperature thresholds of melt pond formation on Antarctic ice shelves
Nature Climate Change, 2023 Melt ponding is an important process for the stability of ice shelves. Here the authors estimate the temperature thresholds at which melt ponding emerges over Antarctic ice shelves and find that cold and dry ice shelves are more vulnerable to melt ...

Widespread slowdown in thinning rates of West Antarctic ice shelves
The Cryosphere, 2023 . Antarctica's floating ice shelves modulate discharge of grounded ice into the ocean by providing a backstress. Ice shelf thinning and grounding line retreat have reduced this backstress, driving rapid drawdown of key unstable areas of the Antarctic Ice
