FORAGING ECOLOGY OF SOUTHERN ELEPHANT SEALS IN RELATION TO THE BATHYMETRY AND PRODUCTIVITY OF THE SOUTHERN-OCEAN
Southern elephant seals (Mirounga leonina) are among the most proficient of mammalian divers and are a major component of the Antarctic food web. Yet little is known of their movements or interaction with their oceanic environment. Specially designed satellite-link data loggers allowed us to visuali...
