The National Oceanic & Atmospheric Administration’s Office of National Marine Sanctuaries has released a new 3-D state of the art sonar map that reveals new details of the USS Hatteras, a sunken Civil War-era warship. The Hatteras, an iron-hulled steamship the U.S. Navy converted into a gunboat, was sunk during a battle with the CSS Alabama.
Â According to the US Bureau of Ocean Energy Management (BOEM), the Hatteras rests in 58 feet of water approximately 20 miles off Galveston, Texas. The BOEM notes that her 210-foot long iron hull is completely buried under about three feet of sand. The BOEM adds that the wreck of the Hatteras is an important part of the story of the Civil War on the Texas coast, as the defense of which is thought to be one of the greatest military feats of the Confederacy.
