About Marianas Trench Marine

Marianas Trench Marine National Monument protects approximately 95,216 square miles of submerged lands and waters in the Mariana Archipelago. Managed jointly by the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration, it encompasses the deepest parts of the world's oceans including Challenger Deep. The monument preserves unique hydrothermal vents, rare deep-sea creatures, and pristine coral reef ecosystems. It serves as a critical habitat for endangered species and provides important scientific research opportunities in one of Earth's most extreme environments.
