Mapping Hatteras

The wreck of the USS Hatteras, a US Navy warship sunk by the Confederate raider CSS Alabama in 1863 is being mapped using a new sonar technique:

The USS Hatteras, an iron-hulled 210-foot-long ship that sunk about 20 miles off the coast of Galveston, Texas, in January 1863, has sat mostly undisturbed and unnoticed since its wreckage was found in the early 1970s. But recent storm-caused shifts in the seabed where the Hatteras rests 57 feet below the surface have exposed more of it to inspection, and researchers are rushing to get as complete an image of the ship as possible before the sand and silt shifts back.

“You can mark Gettysburg or Manassas, (but) how do you mark a battlefield in the sea?” said Jim Delgado, the director of maritime heritage for the National Oceanic and Atmospheric Administration’s Office of National Marine Sanctuaries, and the person overseeing the project.

On Monday, a team of archaeologists and technicians began two days of scanning the wreckage using a sonar imaging technology that hadn’t been used yet at sea, Delgado said.

Here are the Wikipedia links for USS Hatteras and CSS Alabama. I love marine archeology, in case you hadn’t noticed. Which is odd, I suppose, since I don’t dive.

The team hopes to post the images in time for the 150th anniversary of the battle.
