South Georgia (540S; 380W) lies 350 km south of the Polar Front in the south-west Atlantic Ocean. It is a key global location for albatrosses: at the last all-island census in 1986, it was estimated that approximately 92,500 pairs of grey-headed albatrosses (most important global site), 101…
Three species of burrowing seabirds nest on the Diego Ramirez Islands (60 nautical miles south-west of Cape Horn): blue petrels (Halobaena caerulea), common diving petrels (Pelecanoides urinatrix) and sooty shearwater (Puffinus griseus).
The most difficult seabirds in the world to deter from baited hooks are white-chinned petrels, grey petrels and the shearwaters. A fundamental principle of seabird-friendly longlines is that they commence sinking immediately upon deployment and sink fast. Longlines with integrated weight…
Bycatch of seabirds during longline fishing operations is listed under Australian legislation as a key threatening process which could endanger 14 species of seabirds. In 1998 a Threat Abatement Plan (TAP) was finalised to manage this threat.
Chile is a fishery country with important artisanal and industrial longline fleets during the last 30 year. Main fishing resources in southern Chile are Patagonian toothfish, Ling and Austral hake. All these fisheries are suspected to have high seabird mortality.
Abandoned waste dumps in Antarctica pose an environmental hazard due to contaminant … mobilisation in marine and terrestrial habitats. At Casey Station, east Antarctica, a shoreline … waste dump has contaminated adjacent marine sediments with metals, hydrocarbons and organic … carbon.
A series of recruitment experiments using Artificial Substrate Units were deployed in the nearshore waters of Casey Station, (66o17’S, 110o32’E) to investigate spatial and temporal variation in the community structure of small motile invertebrates.
Abstract … A line transect marine science survey of the waters off East Antarctica (80°E-150°E; CCAMLR Division 58.4.1; IWC Areas IV &V) was conducted during the austral summer of 1995/96. A total of 350 hours search effort resulted in 342 sightings (746 animals)…
A biological/oceanographic survey was conducted around the Antarctic Divergence (AD) off Adelie Land, Antarctica by the RTV Umitaka-Maru III of Tokyo University of Fisheries in the 1995/1996 Austral summer. Investigations were included (1) characteristics of oceanic structure, (2)…
A group of pigmented, psychrophilic, strictly aerobic chemoheterotrophs isolated from sea-ice cores collected from coastal areas of eastern Antarctica was found to represent a novel 16S rRNA lineage within the gamma subclass of the Proteobacteria, adjacent to the genus Alteromonas.
