Monitor National Marine Sanctuary was the first national marine sanctuary ever designated in the United States. It protects the wreck of the famed Civil War ironclad USS Monitor, and the sanctuary works with partners to honor and interpret it for the American people.
Monitor National Marine Sanctuary partnered with Stantec and Northrop Grumman's Technology for Conservation program to capture high resolution sonar images of the USS Monitor shipwreck. These fine scale scans highlight how advanced technology can enhance and expand our understanding of the shipwreck and continue Monitor's legacy of innovation for future generations. Explore scans of the shipwreck alongside an interactive timeline, animations, and Monitor related milestones.
Dive 230 feet below the Atlantic Ocean off the North Carolina coast on one of our nation's most historic shipwrecks, USS Monitor. This Civil War ironclad sank in 1862, and in 1975, it became the first national marine sanctuary – Monitor National Marine Sanctuary. Transformed from a weapon of war to an island of marine life, Monitor continues to serve as habitat for a wealth of marine life. Dive in to see sand tiger sharks, sea turtles, and more!
This virtual collection will act as a public resource to display many of the artifacts in pre- and post-treatment status to highlight the benefits of conservation and the science behind the conservation process. Explore the collection to learn more about the USS Monitor's artifacts and the stories these historic treasures can tell about the U.S. Civil War and life at sea in the 1860's.
