The Gulf of Maine is part of the North Atlantic Ocean and lies on the east coast of North America. The gulf borders Cape Cod to the east and Nova Scotia to the northeast. The gulf was named after the colonial Province of Maine, likely named in turn after the French province, and has an area of around 93,000 km2. The Gulf of Maine is home to the highest tidal variation of the planet, 16 meters. The average tidal range is about one meter. Due to the cold waters and these extreme tides, the gulf is a very productive marine environment, home to many plant and animal species.
