Ocean temperature measured by elephant seal-CTDs in the Southern Ocean with links to datasets ...
The potential effects of ocean warming on marine predators are largely unknown, though the impact on the distribution of prey in vertical space may have far reaching impacts on diving predators such as southern elephant seals. We used data from satellite-tracked southern elephant seals from Marion I...
