Here’s a site with an interesting and groundbreaking history. In a joint effort by NASA and the Department of the Interior and the Navy, Tektite was anchored at 50 feet to the seafloor in Greater Lameshur Bay. In 1969, four “aquanauts†spent two months being monitored by behavioral specialists for the psychological effects of extended isolation and the physiological results of breathing compressed air. Divers visiting the site will find a varied terrain of coral-encrusted tunnels, caves and ledges. Tarpon, squid, triggerfish, mackerel and small reef fish thrive here.
