Eddy and tidal driven basal melting of the Totten and Moscow University ice shelves
Frontiers in Marine Science, 2023 The mass loss from the neighboring Totten and Moscow University ice shelves is accelerating and may raise global sea levels in coming centuries. Totten Glacier is mostly based on bedrock below sea level, and so is vulnerable to warm water intrusion ...

Brief communication: widespread potential for seawater infiltration on Antarctic ice shelves [PDF]
The Cryosphere, 2018 Antarctica's future contribution to sea level change depends on the fate of its fringing ice shelves. One factor which may affect the rate of iceberg calving from ice shelves is the presence of liquid water, including the percolation of seawater into ...

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

On the Multiscale Oceanic Heat Transports Toward the Bases of the Antarctic Ice Shelves
Ocean-Land-Atmosphere Research, 2023 The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change. The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic ice shelves.

Journal of Climate, 2022 We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq, %) and intensity (MPI-int, K) of daily maximum summer temperatures exceeding a melt threshold of 273.15 K.

Brief communication: A submarine wall protecting the Amundsen Sea intensifies melting of neighboring ice shelves [PDF]
The Cryosphere, 2019 Disintegration of ice shelves in the Amundsen Sea, in front of the West Antarctic Ice Sheet, has the potential to cause sea level rise by inducing an acceleration of ice discharge from upstream grounded ice. Moore et al.

The origin of green icebergs in Antarctica [PDF]
, 1992 A comparison of samples from a translucent green iceberg with a core from the Ronne Ice Shelf revealed an excellent agreement in isotopic composition, crystal structure, and incorporated sediment particles.

Alternative ice-shelf equilibria determined by ocean environment [PDF]
, 2013 Dynamic and thermodynamic regimes of ice shelves experiencing weak (inline image1 m year−1) to strong (~10 m year−1) basal melting in cold (bottom temperature close to the in situ freezing point) and warm oceans (bottom temperature more than half of a ...

Calving Fronts of Antarctica: Mapping and Classification
Remote Sensing, 2013 Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1
