Fabien Cousteau, grandson of the late French aquanaut Jacques Cousteau, will take part in a 31-day mission this summer at the Aquarius undersea laboratory in the Florida Keys to study the effects of climate change, pollution and acidification on the oceans of the world.

Florida International University, or FIU, which since 2013 has operated the world's only undersea research facility, located at a depth of 19.2 meters (40 feet) off Key West, said that scientists and students are joining Cousteau on "Mission 31."

"The overarching theme for Mission 31 is the human-ocean connection within the lens of exploration and discovery," Cousteau said in a statement.

"Mission 31 pays homage to my grandfather's work and all aquanauts who have since followed his lead in the name of ocean exploration," Fabien Cousteau said.

Jacques-Ives Cousteau (1910-1997) created in 1963 a human habitat at the bottom of the sea dubbed the Aquarius Reef Base and remained there with a team of experts for 30 days.

Mission 31 will set out June 1 and will end July 2, one day more than the legendary French aquanaut

Fabien Cousteau visited the Aquarius base for the first time in 2012 and since then has been planning Mission 31.

Aquarius, managed by FIU, is a laboratory unique in the world, located at some 6 kilometers (3 3/4 miles) off the coast and has been used by 16 teams of astronauts for training in conditions similar to those of outer space.

The underwater base is part of the Florida Keys National Marine Sanctuary at the extreme southern tip of the state. EFE
