01.10.2018 EUCAW Speakers The missing link: pelagic prey field prediction for Southern Ocean marine predators

Southern Ocean predators tend to lead cryptic lives, which in many cases are spent mostly at sea. This makes their foraging behaviour inherently difficult to study. Furthermore, numerous species are threatened through direct human conflict (such as fisheries related mortality), climate driven change, or both. At the European User Conference…
