Divers plan to survey the Civil War ironclad USS Monitor off the North Carolina coast this week with high-definition cameras to look for deterioration in the nearly 150-year-old underwater wreckage.
Jeff Johnston of the Monitor National Marine Sanctuary said Monday the expedition hopes for good weather to allow maximum dives into the 230-foot-deep waters some 16 miles off Cape Hatteras.
Divers ran into tricky currents Sunday and couldn't launch a robotic sub to survey the wreckage.
The dive is under the umbrella of the National Oceanic and Atmospheric Administration, but includes private divers and a team from Rutgers University.
The Monitor is considered the precursor of the modern Navy because of its armor and revolving turret. It sank while being towed to Beaufort in 1862.
