A lifetime at depth: vertical distribution of southern elephant seals in the water column
Although numerous studies have addressed the migration and dive behaviour of southern elephant seals (Mirounga leonina), questions remain about their habita use in the marine environment. We report on the vertical use of the water column in the species and the potential lifetime implications for sou...

Although numerous studies have addressed the migration and dive behaviour of southern elephant seals (Mirounga leonina), questions remain about their habita use in the marine environment.
