State of the Gulf of Maine Report

The Gulf of Maine is a dynamic, changing ecosystem. Bordered by the northeastern United States and the Canadian Maritime Provinces, the Gulf of Maine is one of the largest semi-enclosed coastal seas in North America. It is recognized as one of the world’s richest marine ecosystems with various marine and estuarine habitats, such as salt marshes, seagrass beds, tidal mud flats, underwater rocky outcrops, and kelp beds. Over 10 million people live in the Gulf of Maine watershed. Along its western and northern shores lie the cities and towns of coastal Massachusetts, New Hampshire, Maine, New Brunswick, and Nova Scotia. The Gulf has supported a long tradition of fishing, marine transportation, coastal development, and recreation, and continues to be a valuable resource for the people who live and work in the region.
