LOS ANGELES, March 9 — “Titanic” film director James Cameron yesterday unveiled plans to pilot a specially designed submarine to the deepest point on the planet, the Mariana Trench in the Pacific Ocean southwest of Guam.
The lowest point of the Mariana Trench, known as “Challenger Deep”, has been reached only once before in 1960 when US Navy Lt Don Walsh and Swiss oceanographer Jacques Piccard spent 20 minutes there in the bathyscaphe Trieste. Cameron plans to spend six hours there.

The exploration is a joint project by Cameron, the National Geographic Society, and watchmaker Rolex that is being called the “Deepsea Challenge” and is designed to expand knowledge of unknown portions of Earth.
Cameron’s submersible represents breakthroughs in materials science, structural engineering and imaging through an ultra-small, full ocean depth-rated stereoscopic camera.
Since then he has led six expeditions, written a forensic study of the Bismarck wreck site, and done extensive 3-D imaging of deep hydrothermal vents along the Mid-Atlantic Ridge, the East Pacific Rise and the Sea of Cortez. — Reuters
