Movements of foraging king penguins through marine mesoscale eddies
Despite increasing evidence that marine predators associate with mesoscale eddies, how these marine features influence foraging movements is still unclear. This study investigates the relationship of at-sea movements of king penguins to mesoscale eddies using oceanographic remote sensing and movemen...

Despite increasing evidence that marine predators associate with mesoscale eddies, how these marine features influence foraging movements is still unclear.
