Director James Cameron reached the Earth's deepest point early Monday morning in a solo journey to explore the bottom of the Mariana Trench, nearly seven miles below the surface, the Associated Press said.
Cameron used a specially designed submarine to dive 6.8 miles to the bottom of the Mariana Trench, an area 200 miles southwest of the Pacific island of Guam, MSNBC said.
The director of major films such as "Titanic" and "Avatar" explored and filmed the trench, which is 120 times larger than the Grand Canyon and more than a mile deeper than Mount Everest is tall, the Associated Press said.
In a 12-ton, lime-green submarine called "Deepsea Challenger," Cameron spent 90 minutes to reach the bottom, six hours collecting data and samples for biologists and geologist to study, and roughly 70 minutes returning to the surface, MSNBC said.
A large risk in the dive is the extreme water pressure. At roughly seven miles below the surface, the pressure is equivalent to three SUVs on a toe, MSNBC said.
Cameron has been an oceanography enthusiast since childhood and has made 72 deep-sea dives. Before, during and after the making of his 1997 film "Titanic," he made 33 of his 72 dives to the wreckage of the ship, the Associated Press said.
