Sea Grant is made up of 34 programs, a national Sea Grant Library, and a network of thousands of professionals working in every coastal and Great Lakes state as well as in Guam and Puerto Rico. Additional projects extend Sea Grant's professional network to the Virgin Islands, Marianas Islands and other U.S. territories as well as to U.S. inland states. 

The disciplines of Sea Grant professionals are all grounded in supporting coastal and Great Lakes communities, and they range broadly -- coastal ecology and biology, fisheries biology, aquaculture technology and business, climate change science, community resilience to natural change, economics, social science, youth and adult education, and more. 

Sea Grant professionals may specialize in research, extension, education, communications or other functional areas.
