Ocean acidification (OA) occurs when oceans absorb excess carbon dioxide from the atmosphere, making the pH of seawater lower, or more acidic. This chemistry change can make it more difficult for marine life to form and maintain calcium-rich structures like the skeletons of corals or the shells of many commercially important shellfish. <em>(Video by NOAA’s National Ocean Service)</em>

GCOOS is the only certified observing system whose sole focus is on the Gulf of Mexico

Timely data about the U.S. portion of the Gulf of Mexico and its estuaries from monitored observing stations throughout the region. For use by decision-makers, researchers, government managers, industry, the military, educators, emergency responders and the public.

Working with hundreds of stakeholder communities and learning their needs has helped us to develop products useful for everything from ocean navigation and hurricane trajectories to monitoring coastal areas for harmful algal blooms and tracking the movements of invasive species.

Our Mission

Our mission is to provide on-demand information about the Gulf’s coastal and open ocean waters that is accurate, reliable and benefits people, ecosystems and the economy.
