Jacques Cousteau’s Grandson Is Spending 31 Days Under The Sea. Ask Him Anything!

Send us your questions for Fabien Cousteau, and we'll ask the best ones during an underwater video chat Thursday.

Earlier this week Fabien Cousteau, oldest grandson of ocean explorer Jacques Cousteau, descended to the Aquarius undersea lab of Key Largo, Florida. Cousteau will live in the habitat 31 days, attempting to best the duration his grandfather lived in his undersea habitat, Conshelf II, over 50 years ago.

The Aquarius research lab is positioned roughly 60 feet underwater, and has full life-support systems, including a simple kitchen, bunks, air conditioning and a shower, internet, and portholes that let light in and allow the aquanauts to view the reef and wildlife outside the windows.

We’ll be conducting an interview with Cousteau on Thursday via video conferencing, and will ask him the best questions from our readers about his mission to live underwater for a full month. Tweet us your questions (@PopSci ) or leave them in the comments below.
