Coastal Science for the Granite State

Coastal and marine resources are experiencing unprecedented stresses. Development and population growth along the coast, changes to commercial fishing and aquaculture industries, rising sea levels and increasing flood risk, habitat degredation and invasive species all threaten our nation's coastlines. New Hampshire Sea Grant works to address these issues through integrated research, extension, and education in the Granite State.
