Viscosity and elasticity: a model intercomparison of ice-shelf bending in an Antarctic grounding zone

Journal of Glaciology, 2017
Grounding zones are vital to ice-sheet mass balance and its coupling to the global ocean circulation. Processes here determine the mass discharge from the grounded ice sheet, to the floating ice shelves.

Impacts of local human activities on the Antarctic environment [PDF]

, 2008
We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

, 2002
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Summertime tintinnids in surface water of the Weddell and Cosmonaut seas: community structure and relationships with different water masses

Polar Research, 2023
Tintinnids (Ciliophora) are important microzooplankton grazers. In the Southern Ocean, they are found in the Antarctic Zone, Polar Front and Subantarctic Zone.

Twenty-four buried ice masses remotely mapped in Transantarctic Mountains, Antarctica

Geocarto International, 2023
Glacial ice contains information on paleoclimate, but typically is less than 1 Myrs old because glaciers continuously flow and melt. A recently discovered buried ice mass in Antarctica is dated to 3-5 Myrs and highlights the potential for long ...

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]

, 2017
A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by
