The NOMAD hull was developed from the "Roberts buoy," which was a 6.67-foot-long (2.03 m), 400-pound (181 kg) boat-shaped buoy developed in the early 1940s by the United States Coast and Geodetic Survey to measure strong tidal currents. The buoy's performance was satisfactory, but its limited size significantly restricted its use in other areas.
Between 1951 and 1970, a total of 21 NOMAD buoys were built and deployed at sea. [6] Since the 1970s, weather buoy use has superseded the role of weather ships, as they are cheaper to operate and maintain. [7] The earliest reported use of drifting buoys was to study the behavior of ocean currents within the Sargasso Sea in 1972 and 1973. [8]
