Understanding how changes in oceanographic conditions affect predators and their prey is fundamental for interpreting variability in natural marine ecosystems. At South Georgia, Antarctic fur seals Arctocephalus gazella are known […]
Antarctic fur seal Arctocephalus gazella colonies are found on sub-Antarctic islands around the continent. These islands experience a range of conditions in terms of physical and biological habitat, creating a […]
The view from the south is, more than ever, dominated by ominous signs of change. Antarctica and the Southern Ocean are intrinsic to the Earth system, and their evolution is […]
Vertical shear stress in ice shelves cannot be precisely zero, since the upper and lower surfaces are generally not parallel. By performing stress balance on a vertical column in an […]
Using expressions for ice-shelf creep derived by Weertman (1957) and Thomas (1973[b]) a general method is developed for calculating equilibrium thickness profiles, velocities, and strain-rates for any ice shelf. This […]
Samples from 15 Antarctic and Subantarctic localities were measured and subjected to discriminatory analysis of shell morphology. Only two species were recognized as belonging to the genus Yoldia Möller, 1842: […]
Two species of moss growing in Moss Lake on Signy Island, South Orkney Islands, had unusual morphologies with large leaves and long internodes. Both Calliergon sarmentosum and Drepanocladus cf. aduncus […]
