It is widely accepted that marine biogeography is largely shaped by direct effects of temperature (Angel, 1991; Murawski, 1993). Temperature also influences biodiversity patterns at various latitudes (e.g.,Royet al.,1998; Astorga […]
The Southern Ocean (Figure 11.1) is a major component within the global ocean and climate system. It not only unites the Atlantic Ocean with the Indian and Pacific Oceans, but […]
The continental shelf is the platform for many of the planet’s most productive ecosystems but it is exposed to high disturbance. At high latitudes, massive grounded ice sheets have extended […]
Analysis of the operation of ocean ecosystems requires an understanding of how the structure of the ecosystem is determined by interactions between physical, chemical and biological processes. Such analysis needs […]
The Antarctic Peninsula is one of three areas of the globe currently experiencing rapid regional climate change (King, 1994; Smith et al., 1996, King & Harangozo, 1998; Vaughan et al., […]
The Antarctic continent is almost entirely covered by a vast icecap that reaches 4 km in thickness. Despite this, the continent possesses a remarkable array of lake ecosystems, many of […]
An interpolated bedrock topography is presented for Flask Glacier, one of the tributaries of the remnant part of the Larsen B ice shelf, Antarctic Peninsula. The ice thickness distribution is […]
Antarctic terrestrial biodiversity is challenged by rapid climatic changes and expansion of the human footprint. As well as the potential for environmental damage at the local level, these challenges are […]
Chemosynthetic primary production by microbes supports abundant faunal assemblages at deep-sea hydrothermal vents, with zonation of invertebrate species typically occurring along physico-chemical gradients. Recently discovered vent fields on the East […]
Recent studies have suggested that some resident Antarctic biota are of ancient origin and may have been isolated for millions of years. The phylum Tardigrada, which is part of the […]
A new brittle star attributable to the genus Ophiacantha is described from Antarctic waters, in the diffuse limits of the Antarctic Polar Front at Shag Rocks, South Georgia. The new […]
