For the past three years, Great Bay Coast Watch (GBCW) volunteers have provided the New Hampshire Department of Environmental Services (NHDES) Shellfish Program with significant assistance in performing tasks necessary in managing shellfish resources for human safety. This report describes a continuation of this mutually beneficial partnership. GBCW was founded in 1990 as part of the University of New Hampshire Cooperative Extension/Sea Grant citizen outreach and education program. The GBCW mission is to protect the long-term health of New Hampshires coastal environment through volunteer monitoring and education programs. GBCW is New Hampshires most wide-ranging program for direct citizen involvement in monitoring estuarine waters. The GBCW strives to involve citizens in conservation efforts aimed at the Great Bay Estuarine System, the Hampton/Seabrook Estuary, and the Atlantic Coast of New Hampshire. Citizens are also educated and encouraged to be aware of how activities in their own backyards affect these ecosystems. GBCW includes adults from many occupations, as well as teachers and students from local schools.
