Cameron is the first person to make the dive solo, a distinction that also had been sought by billionaire businessman and adventurer Richard Branson and Patrick Lahey, an experienced submarine pilot.

Cameron told CNN he's not interested in competing for this prize,

"You know, there's so much we don't know," Cameron said. "I'm hopeful that we'll be able to study the ocean before we destroy it."
