PEARL HARBOR (HawaiiNewsNow) - A history lesson of a different kind is happening in Pearl Harbor this week.
A specialized team with high-tech tools is mapping what's beneath the water in hopes of finding ways to better manage historic ships and sites like the USS Arizona Memorial.
Navy Seabee Divers teamed up with the Navy's Fleet Survey Team to map what's inside the harbor by using state-of-the-art sonar technology. They're collecting underwater data on everything from sunken ships to water hazards.
The groups are in town for RIMPAC training.
The data will also be used to help preserve historical moors and fix the Arizona Memorial which has been closed for months after cracks were discovered.
Upon closer inspection in May, the damage was worse than initially thought and short-term repairs have been ongoing.
