Marianas Trench Marine National Monument
Pacific Region


The Fish and Wildlife Service worked closely with key members of Director James Cameron's DEEPSEA CHALLENGE for authorizing the important scientific research, exploration, and recording in the Marianas Trench Marine National Monument, while consulting with our partners at the National Oceanic and Atmospheric Administration and others. Find initial information and follow the exciting DEEPSEA CHALLENGE expedition while it unfolds as the team of experts perfect the engineering and technology that will allow us to see new habitats and species of the Monument at National Geographic's website - Deepsea Challenge

Dr. Patty Fryer commented, “That’s quite a food source.” Raising the unspoken question, “For what … at that depth?” To read more, visit Inside the Expedition.
