Proclaimed in January 2009, the Marianas Trench Marine National Monument protects about 95,216 square miles of submerged lands and waters in three units: the trench itself - the deepest place on Earth - a chain of undersea mud volcanoes and thermal vents, and the waters around three northern islands. The monument contains no dry land and is not open to general visitation; it is managed by the U.S. Fish and Wildlife Service with NOAA.
