Our Mission
The NSF's Ocean Observatories Initiative operates and maintains sophisticated instrumentation in demanding ocean locations to collect and provide data to better understand the ocean, its complexity, and how it is changing because of natural and anthropogenic processes. The OOI connects the community to a wide range of ocean platforms and sensors through its cyberinfrastructure without the need to go to sea.
A Visual journey
A Window into the Changing Planet is a short documentary that shows the beauty and fragility of the ocean and explains how scientists, students, and policymakers are using OOI data to determine how the ocean is changing, at what speed, and what it means for the planet.
