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

The Irminger Array 8 team was aboard the R/V Neil Armstrong in August for the eighth turn of the array. As they transited to the East Greenland Current stations to deploy some floats and drifters, they came out of the fog and were greeted with stunning views of glacial cover mountains and huge icebergs. They saw the 'ice lake', Greenland's largest iceberg estimated to be 4.3 km x 1.8 km in size.

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.
