Mission 31 was an undersea expedition organized by Fabien Cousteau. It was originally scheduled for November 2013, but was delayed to June 2014. On June 1, Cousteau and six crew members descended to the undersea laboratory Aquarius in the Florida Keys. Halfway through the expedition, three of crew were replaced, as had been planned. After 31 days, Cousteau and the crew ascended on July 2. Throughout Mission 31, Cousteau's team conducted extended scuba diving expeditions to collect scientific data and IMAX footage. They hosted various one-day guests, conversed live with classrooms, and kept in touch with the outside world via social media. Cousteau estimated that his team collected the equivalent of two year's worth of surface dive data, enough for 10 scientific papers. Mission 31 was envisioned as a tribute to Cousteau's grandfather, Jacques Cousteau, who spent 30 days living underwater in 1963. Fabien Cousteau thus beat his grandfather's record for time spent underwater by a film crew by one day. ==Background== In 1963, French oceanographer and filmmaker Jacques Cousteau spent 30 days living underwater in Conshelf Two, in the Red Sea.〔 The footage was turned into the Academy Award-winning film ''World Without Sun''. Subsequently, his television show, ''The Undersea World of Jacques Cousteau'', was seen by audiences around the world. Cousteau was one of the world's first advocates for governmental action in environmental protection and, by the time of his death in 1997, was one of the world's most famous television personalities. Jacques Cousteau's grandson, Fabien Cousteau, organized Mission 31 as a tribute to his late grandfather. The mission had two goals — to gather scientific data and to raise funds for Aquarius, an underwater laboratory located at a depth of below the surface, about south of Key Largo.〔〔 Aquarius is the world's only operating undersea laboratory. Measuring by , it holds up to six people.〔 It is pressurized, air conditioned, and has wireless Internet access.〔 A typical mission lasts 10 days, with the longest previous mission lasting 18 days.〔 Aquarius is owned by the United States government's National Oceanic and Atmospheric Administration and run by Florida International University.〔 Fabien Cousteau also hoped to break his grandfather's record for longest time spent underwater by a film crew, and draw the public's attention to environmental issues.〔 According to Guinness World Records, the longest time anyone has spent underwater is 69 days.〔(【引用サイトリンク】title=Longest time spent living underwater )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mission 31」の詳細全文を読む スポンサード リンク
