Surface dynamics and history of the calving cycle of Astrolabe Glacier (Adélie Coast, Antarctica) derived from satellite imagery [PDF]

The Cryosphere
The recent calving of Astrolabe Glacier on the Adélie Coast (East Antarctica) in November 2021 presents an opportunity to better understand the processes leading to ice tongue fracturing.

The Grounding of an Ice Shelf in the Central Arctic Ocean: A Modeling Experiment [PDF]

, 2003
A numerical ice sheet model was used in a first test towards evaluating the hypothesis that, during a period of large-scale glaciation, an ice shelf emanating from the Barents/Kara Seas grounded across parts of the Lomonosov Ridge to a depth of around ...

Inferring the rules of social interaction in migrating caribou [PDF]

, 2018
Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to ...

Fine-scale Antarctic grounded ice cliff 3D calving monitoring based on multi-temporal UAV photogrammetry without ground controlMendeley DataSource code

International Journal of Applied Earth Observations and Geoinformation
Grounded ice cliffs in Antarctica contribute directly to global sea level rise through calving, yet they are less studied compared to floating ice shelves.

The effect of buttressing on grounding line dynamics [PDF]

, 2018
Determining the position and stability of the grounding line of a marine ice sheet is a major challenge for ice-sheet models. Here, we investigate the role of lateral shear and ice-shelf buttressing in grounding line dynamics by extending an existing ...

Surface wave generation due to glacier calving

Oceanologia, 2013
Coastal glaciers reach the ocean in a spectacular process called "calving". Immediately after calving, the impulsive surface waves are generated, sometimes of large height.

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

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Quantifying the seasonal dynamics of a transitional ice cliff-pond system on a debris-covered glacier

Journal of Glaciology
Ice cliffs and supraglacial ponds are key drivers of mass loss on debris-covered glaciers. However, the relationship between melt ponds and adjacent ice cliffs has not been fully explored.

The Bowhead Whale, Balaena mysticetus: Its Historic and Current Status [PDF]

, 1995
The bowhead whale, Balaena mysticetus, is currently listed as endangered under the Endangered Species Act of 1973 and as depleted under the Marine Mammal Protection Act of 1972.
