Stability of Ice Shelves and Ice Cliffs in a Changing Climate [PDF]
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 ...

The marine geological imprint of Antarctic ice shelves [PDF]
Nature Communications, 2019 The recent collapses of ice shelves in Antarctica due to warming make it essential to understand past ice shelf conditions and mechanisms. Here Smith and colleagues review the latest progress in deciphering the geological imprint of Antarctic ice shelves

Rapid disintegration and weakening of ice shelves in North Greenland [PDF]
Nature Communications, 2023 The glaciers of North Greenland are hosting enough ice to raise sea level by 2.1 m, and have long considered to be stable. This part of Greenland is buttressed by the last remaining ice shelves of the ice sheet. Here, we show that since 1978, ice shelves

The role of double-diffusive convection in basal melting of Antarctic ice shelves [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Ocean-driven melting of ice shelves is a leading cause of mass loss from Antarctica. However, the small-scale ocean processes responsible for melting are poorly understood due to the difficulty of making direct measurements in these hard to ...

Sea ice-free corridors for large swell to reach Antarctic ice shelves [PDF]
Environmental Research Letters, 2022 Sea ice can attenuate Southern Ocean swell before it reaches Antarctic ice shelves and imposes flexural stresses, which promote calving of outer ice-shelf margins and influence ice shelf stability.

Annual mass budget of Antarctic ice shelves from 1997 to 2021. [PDF]
Sci Adv, 2023 Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level rise; however, ice shelf health remains poorly constrained. Here, we present the annual mass budget of all Antarctic ice shelves from 1997 to 2021.

Interannual variations in meltwater input to the Southern Ocean from Antarctic ice shelves. [PDF]
Nat Geosci, 2020 Ocean-driven basal melting of Antarctica’s floating ice shelves accounts for about half of their mass loss in steady state, where gains in ice-shelf mass are balanced by losses. Ice-shelf thickness changes driven by varying basal melt rates modulate mass

Progressive unanchoring of Antarctic ice shelves since 1973. [PDF]
NatureMass loss of the Antarctic Ice Sheet has been driven primarily by the thinning of the floating ice shelves that fringe the ice sheet1, reducing their buttressing potential and causing land ice to accelerate into the ocean2.

Surface Melt and Runoff on Antarctic Ice Shelves at 1.5°C, 2°C, and 4°C of Future Warming
Geophysical Research Letters, 2021 The future surface mass balance (SMB) of Antarctic ice shelves has not been constrained with models of sufficient resolution and complexity. Here, we force the high‐resolution Modèle Atmosphérique Régional with future simulations from four CMIP models to

Evaluation of four calving laws for Antarctic ice shelves [PDF]
The Cryosphere, 2023 Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve icebergs and how fast they flow determine whether they advance, retreat, or ...
