Ocean-excited plate waves in the Ross and Pine Island Glacier ice shelves [PDF]
Journal of Glaciology, 2018 Ice shelves play an important role in buttressing land ice from reaching the sea, thus restraining the rate of grounded ice loss. Long-period gravity-wave impacts excite vibrations in ice shelves that can expand pre-existing fractures and trigger iceberg

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation [PDF]
Nature CommunicationsUnderstanding how regime shifts in iceberg calving behavior affect ice shelf stability remains a challenge for numerical models. This is an important question as we consider the fate of the ice shelves that currently buttress the Antarctic Ice Sheet and ...

Widespread movement of meltwater onto and across Antarctic ice shelves [PDF]
Nature, 2017 Surface meltwater drains across ice sheets, forming melt ponds that can trigger ice-shelf collapse acceleration of grounded ice flow and increased sea-level rise.

Calving glaciers and ice shelves [PDF]
Advances in Physics: X, 2018 Calving, or the release of icebergs from glaciers and floating ice shelves, is an important process transferring mass into the world’s oceans. Calving glaciers and ice sheets make a large contribution to sea-level rise, but large uncertainty remains about future ice sheet response to alternative carbon scenarios.

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,

A stress-based poro-damage phase field model for hydrofracturing of creeping glaciers and ice shelves [PDF]
Engineering Fracture Mechanics, 2022 There is a need for computational models capable of predicting meltwater-assisted crevasse growth in glacial ice. Mass loss from glaciers and ice sheets is the largest contributor to sea-level rise and iceberg calving due to hydrofracture is one of the ...

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.

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