A university professor broke a record for the longest time living underwater without depressurization this weekend at a Florida Keys lodge for scuba divers. University of South Florida professor Joseph Dituri spent his 74th day underwater Saturday in a Key Largo lodge for scuba divers. He submerged March 1 and doesn't plan to resurface until June 9, when his mission reaches 100 days. He spent the record-breaking day at the bottom of a 30-foot-deep lagoon in Key Largo much like the previous days, eating eggs and salmon prepared with a microwave, exercising with resistance bands and doing his daily pushups. The Project Neptune 100 mission combines medical and ocean research with educational outreach.
