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

Channelized topography amplifies melt-sensitivity of cold Antarctic ice shelves [PDF]
Nature CommunicationsThe stability of Antarctic ice shelves, which regulate the flow of grounded ice into the ocean, depends critically on ocean-driven basal melting. Basal channels, widespread features beneath many ice shelves, modulate ice-shelf basal melt rates and ...

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 ...

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,

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 ...

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 ...
