Ecosystems and Oceanography Division

The Ecosystems and Oceanography Division (EOD) conducts research to advance our understanding of the structure and dynamics of central North Pacific marine ecosystems. In particular, we seek to understand how marine populations change in response to both direct changes in their predators and prey as well as from broader habitat-based changes in the ocean climate including El Niño, La Niña, and other interannual or decadal events.

    The Kona Integrated Ecosystem Assessment (IEA) project aims to develop a comprehensive understanding of the ecosystem in the Kona coastal region of the island of Hawaii. As part of the research agenda supporting the Kona IEA project, PIFSC scientists have planned a series of shipboard biological and oceanographic surveys along the Kona Coast. More...

    In the past decade, research on satellite-tagged sea turtles has greatly increased our knowledge of the turtles' distribution and movements in the open ocean, information vital to minimizing fishery interactions with these protected pelagic species. Recent collaborative studies are shedding light on the habits of loggerhead turtles in the South Pacific. More...
