James Cameron's dive to the bottom of the ocean

By Curious

James Cameron explorer and filmmaker descended to reach the deepest point in the ocean - the Mariana Trench. He became the first person reaching that point in a solo vehicle and the first person since 1960 to reach the bottom of the ocean in a manned submersible. The adventure started 322 kilometers southwest of Guam into the Pacific Ocean. The journey to the bottom took 2 hours and 36 minutes.
The submersible -- the result of a more than a 7 year engineering effort -- stayed on the bottom for about three hours as Cameron collected samples for research in marine biology, microbiology, astrobiology, marine geology and geophysics. Jim also made photographs and moving photos to visually record the Mariana Trench.

The "Challenger Deep" has only been approached once before in a manned descent, on January 23, 1960, by then US Navy Lieutenant Walsh -- who is a consultant on the DEEPSEA CHALLENGE expedition and was there during Cameron's successful attempt -- and Swiss oceanographer Jacques Piccard in the bathyscaphe Trieste. Walsh and Piccard spent about 20 minutes on the ocean floor before going to the surface.
With breakthroughs in materials and science, structural engineering and new technologies of imaging through a small, full ocean depth-rated stereoscopic camera, Cameron was able to start the DEEPSEA CHALLENGE journey, which he hopes will shed light on other virtually unknown deep-water habitats, such as the New Britain Trench and the Sirena Deep.
