‘Graveyard Of The Atlantic’: Expedition Documents Ironclad Warship That Went Down During The Civil War

An underwater expedition this month found that a Civil War ironclad warship sunk off the coast of North Carolina was still preserved in a time capsule-like state. 

A crew from the National Oceanic and Atmospheric Agency (NOAA) went to Cape Hatteras and sailed out 16 miles to find that the wreck of the USS Monitor, a ship used by the Union during the Civil War, was still in “an excellent state of preservation” on the Atlantic seafloor.
