Unavoidable future increase in West Antarctic ice-shelf melting over the twenty-first century
Nature Climate Change, 2023 Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise.

Antarctic shelf ocean warming and sea ice melt affected by projected El Niño changes
Nature Climate Change, 2023 How the shelf ocean around Antarctica changes with warming is not well known. Here, the authors show that a projected increase in El Niño–Southern Oscillation variability accelerates warming of the Antarctic shelf ocean but slows warming around the sea ...

Detection of Surface Crevasses over Antarctic Ice Shelves Using SAR Imagery and Deep Learning Method
Remote Sensing, 2022 Crevasses are formed by glacier movement and the stresses within glacier ice. Knowledge of the crevasses’ distribution is critical for understanding the glacier and ice shelf stability. In this study, we propose an automated crevasse extraction framework

Intense atmospheric rivers can weaken ice shelf stability at the Antarctic Peninsula
Communications Earth & Environment, 2022 The disintegration of the ice shelves along the Antarctic Peninsula have spurred much discussion on the various processes leading to their eventual dramatic collapse, but without a consensus on an atmospheric forcing that could connect these processes ...

MOSAICKING VERY-HIGH-RESOLUTION HELICOPTER-BORNE IMAGES ACQUIRED OVER DRIFTING ARCTIC SEA ICE USING COTS SENSORS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 In order to observe and record conditions of the sea ice efficiently and specifically during in-situ investigation with the support of icebreaker research vessel (IBRV), the very-high-resolution (VHR) imaging systems have been used in recent past.

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.

Rapid fragmentation of Thwaites Eastern Ice Shelf
The Cryosphere, 2022 . Ice shelves play a key role in the dynamics of marine ice sheets by buttressing grounded ice and limiting rates of ice flux to the oceans. In response to recent climatic and oceanic change, ice shelves fringing the West Antarctic Ice Sheet (WAIS) have ...

An ice-shelf model test based on the Ross Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 1996 A standard numerical experiment featuring the Ross Ice Shelf, Antarctica, is presented as a test package for the development and intercomparison of ice-shelf models. The emphasis of this package is solution of stress-equilibrium equations for an ice-shelf velocity consistent with present observations.

Marine ice in Larsen Ice Shelf [PDF]
Geophysical Research Letters, 2009 It is argued that Larsen Ice Shelf contains marine ice formed by oceanic freezing and other mechanisms. Missing basal returns in airborne radar soundings and observations of a smooth and healed surface coincide downstream of regions where an ocean model predicts freezing.

The distribution and evolution of surface fractures on pan-Antarctic ice shelves
International Journal of Digital Earth, 2023 Surface fractures have a great impact on ice shelf stability in Antarctica and can be considered precursors of ice shelf calving. However, our understanding of the spatial distribution and temporal evolution of surface fractures on the Antarctic ice ...
