SEACOOS was initiated in 2002 with ONR funding

to develop a coastal ocean information system

for FL, GA, SC and NC.

SEACOOS Over-Arching Goal: To significantly increase the quantity and quality of environmental information from the coastal ocean of the SE U.S. and facilitate its use in a wide range of societal, scientific, and educational applications.
