A WHOI moored surface buoy equipped with meteorological and underwater sensors is deployed in the eastern tropical Pacific Ocean from Scripps Institution of Oceanography's R/V Roger Revelle. (Roger Archibald.)

Fixed in strategic ocean locations, surface and subsurface moored observatories can track oceanic processes and airsea interactions that influence Earth's climate.

A proposed network of fixed moored ocean observatories would be chosen among potential sites (red dots), whose strategic value for monitoring and understanding the ocean's role in climate has already been identified. The new sites would complement the existing Tropical Atmosphere Ocean (TAO) array of buoys in the tropical Pacific Ocean (shaded region) and the Pilot Research Moored Array in the Tropical Atlantic (PIRATA) (shaded region), whose deployment began in 1997.

Moored profilers move vertically along mooring cables and measure water properties and currents throughout the water column.
