Renowned filmmaker James Cameron dove into the deepest part of the Earth's oceans on Sunday in his self-designed minisubmarine, according to the New York Times.
In partnership with the National Geographic Society, the expedition landed Cameron's -- "Titanic" and "Avatar" director -- name in the record-book as the third person in the world to have reached the Challenger Deep, the seven-mile abyss and deepest trough of the Mariana Trench, the NY Times said.
Just as the Swiss engineer Jacques Piccard and U.S. Navy Capt. Don Walsh before him, Cameron was only able to remain submerged with visibility of the ocean floor for about 20 minutes before his submarine kicked up so much silt from the floor, NY Times reported. Walsh also accompanied Cameron in helping to advise his mission.
USA Today wrote several weeks ago that Cameron is not the only one who seeks to explore the unknown oceanic depths. Richard Branson, an airline and telecom entrepreneur, and Eric Schmidt, a former Google CEO, are both in the process of creating their own "deep water submarine project" for future expeditions.
