The remains of the only U.S. Navy ship sunk in combat in the Gulf of Mexico during the Civil War can now be seen in high-resolution, 3-D sonar images from the Gulf's murky depths.

The USS Hatteras images are being released this month to coincide with the 150th anniversary of the battle where the 210-foot ship was lost about 20 miles from Galveston. They show previously unknown details like a paddle wheel, the stern and rudder—and a shell hole that may have been among the ship's fatal wounds.

Schell, above a 2012 high-resolution 3-D sonar image from the National Oceanic and Atmospheric Administration.

Archaeologists and technicians spent two days last September mapping the wreckage with sonar imaging technology.

The view is from the vessel's port side, toward its stern. The long paddlewheel shaft, bent and angled, rests on the seabed with the fragmented remains of the port side paddlewheel on the right.

Project manager Jim Delgado, of the , says the images allow views no diver can get because of the murky water.
