On the deepest dive made by a human inside a submarine, a Texas investor and explorer found something he could have found in the gutter of nearly any street in the world: trash.
Victor Vescovo, a retired naval officer, made the unsettling discovery as he descended 10,928 meters to a point in the Pacific Ocean's Mariana Trench that is the deepest place on Earth. His dive went 16 meters lower than the previous deepest descent in the trench.
Vescovo found undiscovered species as he visited places no human had gone before. On the floor of the trench he viewed sea life ranging from shrimp-like anthropods with long legs and antennae to translucent "sea pigs" similar to a sea cucumber.
He also saw angular metal or plastic objects, one with writing on it. "It was very disappointing to see obvious human contamination of the deepest point in the ocean," Vescovo said.
