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 ...

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 ...
