Welcome to the Northeast Canyons and Seamounts Marine National Monument! Located off the coast of southern New England, the Monument is a biologically diverse area of open ocean, larger than Yellowstone National Park. It was established by Presidential Proclamation in 2016 and protects four underwater seamounts (Bear, Mytilus, Physalia, and Retriever Seamounts) and three submarine canyons (Oceanographer, Lydonia, and Gilbert).

      About Us

      The Northeast Canyons and Seamounts Marine National Monument was established to protect and conserve its unique and pristine ocean habitats, historic objects, and features of high scientific interests for current and future generations of Americans.   

       

      What We Do

      Partnered with NOAA, we protect, research, and overlook this rich area of biodiversity. 

      Our Species

      The Monument is know for its abundance of marine mammals, deep-sea corals, rich diversity of fishes, sea turtles, and seabirds.

      Get Involved

      While over 100 miles away from land, there are still some fantastic ways to experience the Monument including recreational fishing and bird and mammal viewing (like whale watching).

      Projects and Research

      Since the early 1900s, researchers have recognized the uniqueness of the waters and submerged lands within the monument boundaries. This recognition has piqued the interests of oceanographers, including physical, geological, chemical, and biological oceanographers.
