“The Office of Naval Research is conducting groundbreaking research into the dangers of working for prolonged periods of time in extreme high and low pressure environments.”
Why? In part, it reflects “the increased operational focus being placed on undersea clandestine operations,” said Rear Adm. Mathias W. Winter in newly published answers to questions for the record from a February 2016 hearing.
“The missions include deep dives to work on the ocean floor, clandestine transits in cold, dark waters, and long durations in the confines of the submarine. The Undersea Medicine Program comprises the science and technology efforts to overcome human shortfalls in operating in this extreme environment,” he told the House Armed Services Committee.
