The main objective of the Predator-Prey Interaction in the Southern Ocean research project is to establish a long-term database of distribution and abundance estimates for krill-dependent predators in the key fishing grounds along the western Antarctic Peninsula. It also focussed on public talks to onboard guests so they can learn the basics for quantifying animal abundance and habitat use understanding the importance of biodiversity protection and how this can be achieved by applying methods for observing marine predators and overlapping its density with krill fisheries.
