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
Image of the week
In November, the Coastal Pioneer Array team will be aboard the R/V Neil Armstrong for the last recovery of the Coastal Pioneer Array. Commissioned in 2016 as a re-locatable coastal array, the Pioneer Array will be relocated to a site in the Southern Mid-Atlantic Bight in the spring 2024. Engineering plans are now underway, and implementation will commence in January 2023 for the complex move. Follow the progress of the plans and progress of the relocation here.

How to participate
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.
