NOAA Commissioned Corps

The National Oceanic and Atmospheric Administration Commissioned Officer Corps, and known informally as the NOAA Corps, is one of seven federal uniformed services of the United States and operates under the National Oceanic and Atmospheric Administration (NOAA), a scientific agency within the Department of Commerce. The NOAA Corps is one of two uniformed services that consist only of commissioned officers, with no enlisted or warrant officer ranks. The other is the United States Public Health Service Commissioned Corps.

Established in 1970, the NOAA Corps is the successor to the United States Coast and Geodetic Survey Corps (1917–1965) and the Environmental Science Services Administration Corps (ESSA Corps) (1965–1970).
