In the outer coastal region, visiting baleen whales migrate northward toward the productive Barents Sea during summer months, where they feed on the large abundance of zooplankton and smaller fish species. These species include the humpback whale (Megaptera novaeangliae), minke whale (Balaenoptera acutorostrata) and fin whale (Balaenopters physalus). It is beyond the scope to provide a complete overview of trends in biodiversity and ecosystem function of the entire North-East Atlantic region here. Indicators within the Nature Index of Norway represent populations of characteristic indigenous species, and the indicator values are based on data from monitoring, model estimates and expert assessments.
