Long-term studies at Bird Island, South … Georgia, show that numbers of wandering, black-browed … and grey-headed albatrosses have been decreasing … since the late 1970s. To determine the status of the total … South Georgia population…
Longline fisheries have been responsible for the deaths of large numbers of seabirds worldwide. Two of the most difficult seabird species to deter from baited hooks are the whitechinned … petrel (Procellaria aequinoctialis) and sooty shearwater (Puffinus griseus).
One hundred and fifteen sperm whales (97 female, 15 male, 3 unknown sex) were involved in three mass stranding events during the month of February 1998 along the west and northwest coastlines of Tasmania, Australia. Sixty-six of these whales stranded at Ocean Beach, Strahan; 35 at Greens Beach…

: P vs E experiments determining photosynthetic parameters and daily primary production were carried out east of Kerguelen Island during the KEOPS cruise in January and February 2005. The Kerguelen Plateau region is naturally enriched with iron, while deeper waters (>1000m) nearby may not be.
The isotopes of nitrate, which show different dynamics than nitrate concentration during physical transport and nitrate assimilation, provide a complementary constraint in the effort to understand nutrient transport and biogeochemical fluxes in the Southern Ocean. For instance…
