The NOAA Commissioned Corps, established in 1917 as the Coast and Geodetic Survey Corps, and then as the Environmental Science Services Administration (ESSA) Corps from 1965-1970, traces its roots back to the former U.S. Coast and Geodetic Survey, which dates back to 1807 and President Thomas Jefferson. The U.S. Coast and Geodetic Survey officers were commissioned so that under the laws of war, they could not be executed as spies if they were serving as surveyors on a battlefield.
The NOAA Corps today provides a cadre of professionals trained in engineering, earth sciences, oceanography, meteorology, fisheries science, and other related disciplines. Officers operate ships, fly aircraft, manage research projects, conduct diving operations, and serve in staff positions throughout NOAA.
Uniforms
The NOAA Corps uses the same ranks as the United States Navy and the United States Coast Guard commissioned officers, from Ensign to Vice Admiral. NOAA Corps now wears the Operational Dress Uniform (ODU), the same as the United States Coast Guard for all of its work uniforms, replacing the previously used USN working uniforms. NOAA Corps also wears the Service Dress Blues (SDBs) and Service Dress Whites of the US Navy but wear special corps insignia to identify them as a member of the NOAA Corps. The Vice Admiral rank however is no longer an active grade and the current highest ranking officer in the NOAA Corps is a two-star Rear Admiral. Corps officers also receive the same pay and grade as their military counterparts. Corps officers receive direct commissions into the service, much as the other Uniformed Services of the United States induct officers via direct commission officer programs.
