Rheological control of crystal fabrics on Antarctic ice shelves

Journal of Glaciology
Ice crystal fabrics can exert significant rheological control on ice sheets and ice shelves, potentially softening or hardening anisotropic ice by several orders of magnitude compared to isotropic ice. We introduce an anisotropic extension of the Shallow

To what extent is there a mechanical coupling between Antarctic ice-shelves and sea-ice?

, 2019
Understanding the causes of recent trends in Antarctic ice shelves and sea ice is crucial for improving our modelling capabilities to predict the future state of the Antarctic Ice Sheet and its future contribution to sea level rise.

Late Pleistocene glacial terminations accelerated by proglacial lakes [PDF]

Climate of the Past
During the glacial cycles of the past 800 000 years, Eurasia and North America were periodically covered by large ice sheets, causing up to 100 m of sea-level change.

Antarctic ice-shelf meltwater outflows in satellite radar imagery: ground-truthing and basal channel observations

Journal of Glaciology
Ice shelves regulate the flow of the Antarctic ice sheet toward the ocean and its contribution to sea-level rise. Accurately monitoring the basal and surface melting of ice shelves is therefore essential for predicting the ice sheet's response to ...

Flow lines on Antarctic ice shelves

, 1980
Satellite images of Ronne and Filchner ice shelves show a variety of surface features many of which are believed to indicate flow lines in the ice. Sufficient imagery is now available from Landsat satellites to plot these features from mosaics.

The Importance of Sea Ice to Antarctic Ice Shelves

Frontiers for Young Minds
Ice shelves are important because they act as a dam that regulates the amount of land ice that flows into the ocean. This means if Antarctica’s ice shelves were to break up, more ice would be melted into the ocean and global sea level would rise at a much faster rate.

The influence of ice shelves on the Antarctic Ice Sheet during the Miocene

, 2021
The atmospheric concentration of CO 2 is currently over 400 ppm and is projected to exceed 500 ppm in the coming decades. A climatic era with similar levels of CO 2 is the Miocene which showed evidence of large scale variability, speed-up, and retreat of

When will the Antarctic ice shelves not be viable anymore?

International audienceThe Antarctic contribution to sea-level rise in the coming centuries remains very uncertain, due to the possible triggering of instabilities such as the Marine Ice Sheet Instability (MISI) and Marine Ice Cliff Instability (MICI ...
