Criticism was mounting Friday ahead of President Trump's trip to Maine, where he was expected to ease some of the protections for the Northeast Canyons and Seamounts National Monument, a biologically robust area located about 100 miles southeast of Cape Cod National Seashore that became the Atlantic Ocean's first national monument when established by President Obama in 2016.
According to the NOAA Fisheries, the nearly 5,000 square-mile monument "includes two distinct areas, one that covers three canyons and one that covers four seamounts. These undersea canyons and seamounts contain fragile and largely pristine deep marine ecosystems and rich biodiversity, including important deep sea corals, endangered whales and sea turtles, other marine mammals and numerous fish species."
