Antarctic Seabed Assemblages in an Ice-Shelf-Adjacent Polynya, Western Weddell Sea [PDF]
Biology, 2022 Ice shelves cover ~1.6 million km2 of the Antarctic continental shelf and are sensitive indicators of climate change. With ice-shelf retreat, aphotic marine environments transform into new open-water spaces of photo-induced primary production and ...

Winter thermohaline evolution along and below the Ross Ice Shelf [PDF]
Nature CommunicationsThe Ross Ice Shelf floats above the southern sector of the Ross Sea and creates a cavity where critical ocean-ice interactions take place. Crucial processes occurring in this cavity include the formation of Ice Shelf Water, the coldest ocean water, and ...

The internal structure of the Brunt Ice Shelf from ice-penetrating radar analysis and implications for ice shelf fracture [PDF]
The Cryosphere, 2018 The rate and direction of rift propagation through ice shelves depend on both the stress field and the heterogeneity (or otherwise) of the physical properties of the ice.

Formation of sea ice ponds from ice-shelf runoff, adjacent to the McMurdo Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 2020 Ponds that form on sea ice can cause it to thin or break-up, which can promote calving from an adjacent ice shelf. Studies of sea ice ponds have predominantly focused on Arctic ponds formed by in situ melting/ponding.

Measurements of Ice Shelf Water beneath the front of the Ross Ice Shelf using gliders [PDF]
Annals of Glaciology, 2017 Measurements made by an underwater glider deployed near the Ross Ice Shelf were used to identify the presence of Ice Shelf Water (ISW), which is defined as seawater with its potential temperature lower than its surface freezing point temperature ...

Past and future dynamics of the Brunt Ice Shelf from seabed bathymetry and ice shelf geometry [PDF]
The Cryosphere, 2019 The recent rapid growth of rifts in the Brunt Ice Shelf appears to signal the onset of its largest calving event since records began in 1915. The aim of this study is to determine whether this calving event will lead to a new steady state in which the ...

OBSERVATIONS OF CONTINUOUS INSTABILITY FOR SCAR INLET ICE SHELF, ANTARCTIC PENINSULA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Observation of the evolving instability of ice shelves plays a very important role in global change research. Following the suddenly large-scale collapse of the Larsen B Ice Shelf in the Antarctic Peninsula in 2002, the evolving instability for its ...

Widespread slowdown in thinning rates of West Antarctic ice shelves [PDF]
The Cryosphere, 2023 Antarctica's floating ice shelves modulate discharge of grounded ice into the ocean by providing a backstress. Ice shelf thinning and grounding line retreat have reduced this backstress, driving rapid drawdown of key unstable areas of the Antarctic Ice ...

Shear-margin melting causes stronger transient ice discharge than ice-stream melting in idealized simulations [PDF]
The Cryosphere, 2022 Basal ice-shelf melting is the key driver of Antarctica's increasing sea-level contribution. In diminishing the buttressing force of the ice shelves that fringe the ice sheet, the melting increases the ice discharge into the ocean.

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
