The Southern Ocean and more specifically the sea-ice zone supports globally significant ecosystems including abundant populations of marine mammals and seabirds.

Among the activities included in the habitat use concept, foraging is one of the most important because obtaining adequate food supply is a basic requirement of all other life-history traits. The optimal foraging theory predicts that predators should adjust their movements and behaviour in relation to prey density (in both horizontal and vertical dimensions in the case of marine predators).
