The incidence of plastic in the diets of Antarctic seabirds
Abstract: We investigated the diets of seabirds at sea in the Antarctic from 1976 to 1988. During ... the study period, on eight cruises in the Ross, southern Scotia, and Weddell Seas and Drake Passage ... , we collected or pumped the stomachs of 1,223 seabirds of 23 species. The stomach contents of species ... that feed below the sea surface contained little plastic, as expected; these birds live entirely on ...

Results of the sixth Ross Sea shelf survey to monitor abundance of sub-adult Antarctic toothfish in the southern Ross Sea, January 2017
Abstract: At its 2011 meeting, the Scientific Committee agreed that a time series of relative ... abundance from a well-designed survey could be a useful input into the Ross Sea stock assessment model. In ... this paper we provide results of the sixth annual survey in the time series. The objectives of this ... survey included monitoring sub-adult (≤ 110 cm TL) toothfish in the south of SSRUs 881.J and 881.L in the ...

Abstract: The Southern Ocean is known to have warmed considerably during the second half of the ... 20th century but there are few locations with data before the 1950s. In addition, assessments of change ... in this region are hampered by the strong seasonal bias in sampling, with the vast majority of data ... collected during the austral summer. However, oceanographic measurements near South Georgia span most of the ...

CIRCULATION IN THE ROSS SEA SECTOR OF THE SOUTHERN OCEAN: REPRESENTATION IN NUMERICAL MODELS
Abstract: The circulation in the Ross Sea sector of the Southern Ocean is examined in three ... numberical models of intermediate to high resolution. Despite the model differences (including physics ... , forcing) the circulation representation is relatively consistent, both in terms of the mean and some ... aspects of monthly variability. This could point to strong bathymetric constraints on the circulation. In ...

Features of spatial and temporally distribution patterns of krill flux in the Scotia Sea: some comments on the development of a krill fishery management in Area 48.
Abstract: The spatial variability of krill flux in the Scotia Sea calculated by using the ... geostrophic method, is analysed. For this, CCAMLR-2000 international survey data was used. The analysis was ... carried out in the 0-500 m depth ranges 50 m layers. Water mass geostrophic circulation, spatial ... to the Scotia Sea, were a subject of study. It is clearly illustrated that the geostrophic krill ...
