SeaLab III was a U.S. Navy undersea habitat slated for San Clemente Island waters in 1969. This film documents one aspect of the SeaLab III project called DIVERCON 1, which was a ten foot diameter and ten foot high modular dry repair and storage facility standing on adjustable legs and anchored. Designed by the U.S. Naval Civil Engineering Laboratory at Port Hueneme, underwater construction techniques and methods by divers were tested in water tanks at UCLA and in the ocean offshore Anacapa Island. An underwater lighting chandelier was developed to illuminate an underwater construction site. DIVERCON 1 remained on the bottom off Anacapa Island for a month until recovery by a ship.
