Joseph Dituri spent 100 days underwater in the Florida Keys. The goal was to "extend human tolerance to the underwater world," he said.
He also taught a course at the University of South Florida and hosted more than 60 visitors. The previous record of 73 days was set by two Tennessee professors in the same accommodation in 2014."The most rewarding thing about all this is the interaction with almost 5,000 students and the fact that they care about conserving, protecting and rejuvening our marine environment," he says.
