Collaborative Research: The Distributed Biological Observatory (DBO)-A Change Detection Array in the Pacific Arctic Region

Several regionally critical marine sites in the Pacific Arctic sector that have very high biomass and are focused foraging points for apex predators, have been reoccupied during multiple international cruises. The data documenting the importance of these ecosystem "hotspots" provide a grow...
