Fishes on the Antarctic continental shelf: evolution of a marine species flock?
Distance, currents, deep water and sub-zero temperatures isolate the waters of the Antarctic continental shelf from other shelf areas in the Southern Hemisphere. The Antarctic shelf is an insular evolutionary site for a variety of marine organisms. The fish fauna is relatively small and unusual in composition, consisting of 213 species with higher taxonomic diversity restricted to 18 families. ...
متن کاملTrophic ecology of seven Antarctic gorgonian species
The trophic ecology of Antarctic anthozoans and their role in benthic−pelagic coupling processes is poorly understood. We studied 7 gorgonian species (Primnoisis sp., Fannyella nodosa, Ainigmaptilon antarcticum, Notisis sp., Primnoella sp., Dasystenella sp. and Thouarella sp.) in 2 Antarctic regions: the Eastern Weddell Sea and the Bransfield Strait (Antarctic Peninsula) in austral autumn 2000,...
متن کاملCross–Shelf Exchange Along the Antarctic Continental Margin: Modeling Results
The shelf areas around the Antarctic Continent are locations of dense water formation; part of these water masses ventilate the adjacent deep ocean basins and enter the global thermohaline circulation. This paper takes a look at regional differences of shelf sea–deep ocean exchange in high southern latitudes (mainly between the Weddell and Ross Seas), highlights a few physical mechanisms potent...
متن کاملDistribution of Upper Circumpolar Deep Water on the warming continental shelf of the West Antarctic Peninsula
We use autonomous underwater vehicles to characterize the spatial distribution of Upper Circumpolar Deep Water (UCDW) on the continental shelf of the West Antarctic Peninsula (WAP) and present the first near-synoptic measurements of mesoscale features (eddies) containing UCDW on the WAP. Thirty-three subsurface eddies with widths on the order of 10 km were detected during four glider deployment...
متن کاملHabitat Specialization in Tropical Continental Shelf Demersal Fish Assemblages
The implications of shallow water impacts such as fishing and climate change on fish assemblages are generally considered in isolation from the distribution and abundance of these fish assemblages in adjacent deeper waters. We investigate the abundance and length of demersal fish assemblages across a section of tropical continental shelf at Ningaloo Reef, Western Australia, to identify fish and...
