How Does the Ocean Melt Antarctic Ice Shelves?

MG Rosevear, B Gayen, CA Vreugdenhil… - Annual Review of …, 2024 - annualreviews.org
The present-day state and future of the Antarctic Ice Sheet depend on the rate at which the

Twenty-first century sea-level rise could exceed IPCC projections for strong-warming futures

M Siegert, RB Alley, E Rignot, J Englander, R Corell - One Earth, 2020 - cell.com
While twentieth century sea-level rise was dominated by thermal expansion of ocean water,
mass loss from glaciers and ice sheets is now a larger annual contributor. There is …

The influence of Pine Island Ice Shelf calving on basal melting

AT Bradley, DT Bett, P Dutrieux… - Journal of …, 2022 - Wiley Online Library
The combination of the Pine Island Ice Shelf (PIIS) draft and a seabed ridge beneath it form
a topographic barrier, restricting access of warm Circumpolar Deep Water to a cavity inshore …

Iceberg melting substantially modifies oceanic heat flux towards a major Greenlandic tidewater glacier

BJ Davison, TR Cowton, FR Cottier, AJ Sole - Nature communications, 2020 - nature.com
Fjord dynamics influence oceanic heat flux to the Greenland ice sheet. Submarine iceberg
melting releases large volumes of freshwater within Greenland's fjords, yet its impact on fjord …
