Ocean Data Day
June 25, 2026
From the cold waters of the Arctic to the tropical Pacific Islands to the world’s largest system of freshwater lakes, U.S. regions are incredibly diverse – and so are the economies they support. Coastal and Great Lakes industries generate billions in economic activity and support millions of jobs, all of which depend on accurate, real-time ocean and coastal data.
IOOS coastal observing systems deliver that data – supporting safe maritime transportation, sustainable fisheries and aquaculture, coastal tourism, and offshore energy. By providing accessible, decision-ready information, IOOS helps businesses operate with confidence, reduce risk, and adapt to changing conditions.
Ocean Data Day highlights the value of this data and the people behind it.
This year’s theme, Coastal Data for a Strong Economy, underscores how ocean data powers economic activity – guiding ships into port, informing fishing operations, and helping keep our ocean economy moving.
