As of Monday, virtually all commercial fishing will be banned from the newly created Marine National Monument that includes the Northeast Canyons and Seamounts off the coast of southern New England.
The closure includes more than 4,900 square miles of ocean, or about the same area as the state of Connecticut, about 130 miles east-southeast of Cape Cod.
The Northeast Canyons represent 941 square miles of that total, while the protection afforded the Seamounts stretches over 3,972 square miles.
