What is OOI?

The Ocean Observatories Initiative (OOI) is a science-driven ocean observing network that delivers real-time data from more than 800 instruments to address critical science questions regarding the world’s oceans. 

Funded by the National Science Foundation to encourage scientific investigation, OOI data are freely available online to anyone with an Internet connection.

The OOI has three major observatory elements linked together by instrument, infrastructure, and an information management system.

  • Global Ocean Arrays
  • Regional Cabled Arrays
  • Coastal Arrays

Glass balls and dual acoustic releases are deployed for the the Mesoscale Flanking Mooring B at Global Station Papa,  located in the Gulf of Alaska next to the NOAA Pacific Marine Environmental Laboratory Surface Buoy. The region is extremely vulnerable to ocean acidification, has a productive fishery, and low eddy variability. It is impacted by the Pacific Decadal Oscillation and adds to a broader suite of OOI and other observatory sites in the Northeast Pacific.

OOI brings data to your doorstep, without ever having to go to sea. Opportunities exist to customize OOI data by adding instruments or platforms to the existing infrastructure, proposing additional or modified sampling, participating in cruises, borrowing OOI equipment, or simply exploring real-time data to answer scientific questions.  Explore the ways you can participate in the OOI.
