An American undersea explorer has completed what is claimed to be the deepest manned sea dive ever recorded -- returning to the surface with the depressing news that there's plastic trash down there.
Victor Vescovo journeyed 10,927 meters (35,853 feet) to the bottom of the Challenger Deep , the southern end of the Pacific Ocean's Mariana Trench, as part of a mission to chart the world's deepest underwater places.
Making multiple trips nearly 11 kilometers, or seven miles, to the ocean floor -- one of them four hours in duration -- Vescovo set a record for the deepest solo dive in history, his team said. The previous record was held by "Titanic" director James Cameron in 2012.
