Fabien Cousteau, grandson to the famed ocean explorer Jacques-Yves Cousteau, just completed a 31 day study of how humans impact ocean life, all while living in an underwater laboratory.
The 46-year old ocean explorer and documentary filmmaker lived in an underwater lab that was 63 feet deep off the coast of Key Largo, Florida for a month. During that time, Cousteau studied the impacts of climate change and man-made pollutions on ocean life for a project called Mission 31.
Cousteau lived in the underwater lab, called Aquarius, for 31 days on end, not bothering to come back to land until Wednesday. This is the longest time anyone has lived in an underwater lab, as Aquarius normally only does 10 day missions.
During the month Cousteau was underwater, scientists and researchers from Florida International University in Miami joined him for two week shifts.
“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.”
During Cousteau’s trip, he frequently performed Skype interviews with schools all over the world, as well as taking numerous pictures and videos of the ocean that he lived in.
Fabien Cousteau is known for making a number of documentary films about ocean life and the dangers humans cause for it.
