SEACOOS functioned as a pilot regional coastal ocean observing system that has significantly advanced our national ability to establish operational regional observing systems around the country. The final year focused on documentation of the program's best practices, lessons learned and on maintaining those elements of the coastal ocean observing system (COOS) that could be preserved given the reduced level of fending. A special volume was published in fall 2008 that includes 9 articles by investigators which detail the components developed, define best practices and lessons learned. An additional 128 publications were authored by investigators during the lifetime of the program that describe advances in basic scientific understanding of coastal ocean processes and in more applied science with a focus on ecosystem functioning. A number of SEACOOS program elements have been transitioned to the Southeast Coastal Ocean Observing Regional Association (SECOORA); the SEACOOS data management program now forms the basis for the SECOORA data management system and all HF radar installations continue to operate.
