Mariana Trench – James Cameron Hits Bottom Of Sea
James Cameron visits bottom of Mariana Trench in deep sea vessel

James Cameron has reached the bottom of the Pacific Ocean’s Mariana Trench. He officially arrived at the bottom of the trench at 6pm ET (11pm BST) on Sunday (March 25, 2012) and returned to the surface in the early hours of Monday morning. “All systems okay,” he is quoted as saying on reaching the end of his seven-mile journey.

A post on James Cameron’s Twitter account read: “Just arrived at the ocean’s deepest pt. Hitting bottom never felt so good. Can’t wait to share what I’m seeing w/ you @DeepChallenge”

Cameron spent six hours in the trench capturing footage for a documentary, also collecting samples from the ocean floor during his visit.

He is only the second person to make the dive, and the first to do it alone. The first dive took place in 1960 — that was when U.S. Navy Lt. Don Walsh and Swiss oceanographer Jacques Piccard made the journey to the Mariana Trench.
