SG meaning in Academic & Science ?

The National Sea Grant College Program is a program of the National Oceanic and Atmospheric Administration (NOAA) within the U.S. Department of Commerce. It is a national network of 34 university-based Sea Grant programs involved in scientific research, education, training, and extension projects geared toward the conservation and practical use of the coasts, Great Lakes, and other marine areas. The program is administered by the National Oceanic and Atmospheric Administration (NOAA) with the national office located in Silver Spring, Maryland. There are Sea Grant programs located in every coastal and Great Lakes state as well as in Puerto Rico and Guam.

The program was instituted in 1966 when Congress passed the National Sea Grant College Program Act.

Sea Grant programs and colleges are not to be confused with land-grant colleges (a program instituted in 1862), space-grant colleges (instituted in 1988), or sun-grant colleges (instituted in 2003), although an institution may also be in one or more of the other programs concurrently with being a sea-grant institution.
