Long Beach has the only municipal port security diving unit in the U.S. certified to dive with hard hats. It installs pipelines, inspects bridges and shipwrecks, and responds to security risks.
As the sun rises over the Port of Long Beach, two hard-hat divers step off the edge of a harbor patrol dive boat and splash into the murky waters a half-mile offshore. Their mission: to investigate the sonar blips that suggest there is a large submerged object menacing a busy shipping lane.
