James Cameron’s submersible craft Deepsea Challenger reemerged from its record-breaking dive into the Challenger Deep of the Mariana Trench. Challenger Deep is the deepest known point in the Earth’s oceans. His dive ended today at 2 UTC (9 p.m. CST on March 25, 2012). Cameron is a National Geographic explorer and filmmaker. Moreover, he is the first human being to reach the bottom of the 6.8-mile-deep (11-kilometer-deep) undersea trench. Therefore, he is traveling in what some call his “vertical torpedo.”
The Mariana Trench in the western Pacific is an unusually deep feature in the ocean floor. Challenger Deep is a slot-shaped depression within the Mariana Trench. Its bottom is 11.3 km (7 miles) long and 1.6 km (1 mile) wide, with gently sloping sides. And Challenger Deep is located at the southern end of the Mariana Trench.
James Cameron has become the first human to reach and return solo from the 6.8-mile-deep (11-kilometer-deep) undersea Challenger Deep in the Mariana Trench in the western Pacific. He descended solo in his craft Deepsea Challenger. And the depth his craft recorded was 10,898 metres (35,755 ft) when he touched down.
