The USS Arizona is in "far better shape than can be imagined based on scientific evidence," says Brett Seymour, of the National Park Service.
Navy divers are helping the Park Service map the hull of the sunken battleship using 3-D, high-definition imaging. The Park Service is finding soft and hard coral on the battleship -- where no hard coral was growing in the 1980s.
Also under way is a film of the underwater world of the Arizona that will be shown in the new visitors center.
Officials say the new technology helps them better understand the structural integrity of the 93-year-old vessel and whether it is any danger to the environment.
The camera system also will be used to videotape a Japanese midget submarine sunk off Pearl Harbor in the 1941 attack.
