In 2011, the Convention on Biological Diversity established science-based criteria for designating Ecologically or Biologically Significant Areas (EBSAs) on the high seas and instructed regional fisheries management organizations to identify and protect these areas. This project will conduct a global analysis of oceanographic data to identify potential EBSAs that focus on important pelagic habitats for tunas, sharks, seabirds, and endangered species and link oceanographic features with habitat use by large pelagic predators.
