Coast & Geodetic Survey Meritorious Service Medal

The original ancestor organization of the NOAA Corps, the United States Coast and Geodetic Survey Corps, existed from 1917 to 1965, then went through a transitional period as the Environmental Science Services Administration Corps (ESSA Corps) from 1965 to 1970 before becoming the NOAA Corps.

Awarded to any Coast and Geodetic Survey commissioned officer or to any ship's officer or member of the crew of any Coast and Geodetic Survey ship who rendered service of a meritorious character between 8 September 1939 and 28 April 1952 but not of such an outstanding character as would warrant an award of the Coast and Geodetic Survey Distinguished Service Ribbon.
