Researcher spending 100 days inside Florida underwater hotel

Retired U.S. Navy commander Joseph Dituri, 55, who holds a doctorate in biomedical engineering and teaches hyperbaric medicine, plans to live and work until June 9 at Jules? Undersea Lodge. The facility, situated 30 feet beneath the surface in a Key Largo lagoon, was originally fabricated as a marine research laboratory and converted into an underwater hotel in 1986.
