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 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

Response of Pacific-sector Antarctic ice shelves to the El Niño/Southern Oscillation [PDF]
Nature Geoscience, 2018 Satellite observations over the past two decades have revealed increasing loss of grounded ice in West Antarctica, associated with floating ice shelves that have been thinning.

Freshening by glacial meltwater enhances melting of ice shelves and reduces formation of Antarctic Bottom Water [PDF]
Science Advances, 2018 Glacial meltwater stops bottom-water formation, allowing warm ocean waters to reach Antarctic ice shelves and drive rapid melting. Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool and salinify waters on the ...

Interannual variations in meltwater input to the Southern Ocean from Antarctic ice shelves [PDF]
Nature Geoscience, 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

Can unconfined ice shelves provide buttressing via hoop stresses? [PDF]
Journal of Glaciology, 2020 The stress balance within an ice shelf is key to the resistance, or buttressing, it can provide and in part controls the rate of ice discharge from the upstream ice sheet. Unconfined ice shelves are widely assumed to provide no buttressing.

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.

The role of double-diffusive convection in basal melting of Antarctic ice shelves. [PDF]
Proc Natl Acad Sci U S A, 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
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.
