 Edwin Clayton Link, 31, and Albert Dennison Stover, 51, died from carbon dioxide poisoning after the submersible Johnson Sea Link was entangled for over 24 hours at a depth of 110 m (360 ft) on the USS Fred T. Berry artificial reef. After failed attempts by U.S. Navy divers and a Navy submersible, the Johnson Sea Link was freed by the commercial salvage vessel A.B. Wood II using an underwater television camera and grappling hook. The submersible pilot, Archibald “Jock” Menzies, and scientist Robert Meek survived. The designer of the submersible and father of Clayton Link, Edwin A. Link, subsequently designed an unmanned Cabled Observation and Rescue Device (CORD) that could free trapped submersibles.
