Can rifts alter ocean dynamics beneath ice shelves? [PDF]

open access: yesThe 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]

open access: yesThe 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 ...

The role of föhn winds in eastern Antarctic Peninsula rapid ice shelf collapse [PDF]

open access: yesThe Cryosphere, 2022
Ice shelf collapse reduces buttressing and enables grounded glaciers to contribute more rapidly to sea-level rise in a warming climate. The abrupt collapses of the Larsen A (1995) and B (2002) ice shelves on the Antarctic Peninsula (AP) occurred, at ...

Sea ice-free corridors for large swell to reach Antarctic ice shelves

open access: yesEnvironmental 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.

High-resolution spatio-temporal analysis of snowmelt over Antarctic Peninsula ice shelves from 2015 to 2021 using SAR images

open access: yesInternational Journal of Digital Earth, 2023
Ice shelves play an essential role in the dynamics of the Antarctic ice sheet. The surface meltwater is important, as it can irreversibly weaken ice shelves by exerting additional hydrostatic pressure.

A 15-year circum-Antarctic iceberg calving dataset derived from continuous satellite observations [PDF]

open access: yesEarth 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.

Creep deformation and buttressing capacity of damaged ice shelves: theory and application to Larsen C ice shelf [PDF]

open access: yesThe Cryosphere, 2013
Around the perimeter of Antarctica, much of the ice sheet discharges to the ocean through floating ice shelves. The buttressing provided by ice shelves is critical for modulating the flux of ice into the ocean, and the presently observed thinning of

Eddy and tidal driven basal melting of the Totten and Moscow University ice shelves

open access: yesFrontiers in Marine Science, 2023
The mass loss from the neighboring Totten and Moscow University ice shelves is accelerating and may raise global sea levels in coming centuries. Totten Glacier is mostly based on bedrock below sea level, and so is vulnerable to warm water intrusion ...

On the Multiscale Oceanic Heat Transports Toward the Bases of the Antarctic Ice Shelves

open access: yesOcean-Land-Atmosphere Research, 2023
The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change. The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic ice shelves.
