The Northeast Canyons and Seamounts Marine National Monument is a marine national monument of the United States off the coast of New England, on the seaward edge of Georges Bank. It was created by President Barack Obama on September 15, 2016, as the first U.S. marine national monument in the Atlantic Ocean. The area includes four underwater mountains and three deep-sea canyons. It is home to endangered whales and other rare species, some found nowhere else in the world.
