Fabien Cousteau to Spend 31 Days Underwater

Jacques-Ives Cousteau’s grandson plans to lead a team this fall that will spend 31 days underwater in the Florida Keys National Marine Sanctuary.

Fabien Cousteau and his team will live in the Aquarius undersea habitat, according to a statement posted on his website.

No exploration team has ever spent 31 full days submerged underwater in the name of science and discovery, but a new ocean exploration endeavor named Mission 31 led by noted filmmaker and oceanographic explorer, Fabien Cousteau, will launch this fall to test new science and tech-based experiments with underwater motorcycles, autonomous robots and Kirby Morgan tech diving helmets, according to the statement.

Cousteau announced the endeavor on June 11, the anniversary of his grandfather’s birthday.

Aquarius is owned by the U.S. National Oceanic and Atmospheric Administration and managed by Florida International University. Mission 31 will be the longest activity Aquarius has ever hosted, according to the statement.

Cousteau’s endeavour will break new ground in ocean exploration and also coincides with the 50th anniversary of a monumental legacy left by is grandfather Jacques-Yves Cousteau, credited with creating the first underwater habitats for humans and leading a team of ocean explorers on the first attempt to live and work underwater aboard Conshelf Two. The ambitious 30-day living experiment in the Red Sea succeeded as the first effort in saturation diving, proving that it could be done without suffering any ill effects. Mission 31 will expand the 50-year-old Cousteau legacy by one full day, 30 more feet of saturation and will broadcast every second on multiple channels exposing the world to the adventure, risk and mystique of what lies beneath.
