There's a more complete video on the National Geographic website, but try as I might I can't seem to be able to embed it!
James Cameron is now the third person (and the only one to have done it solo) to have reached the Ocean's deepest point in the Mariana Trench! I first happened upon the story via the fabulous site io9, and while reading the story I just linked to, what particularly hit me was the fact that humans have only visited the bottom of the Mariana Trench ONCE, in 1960 (there have also been two unmanned trips)! To think, we've sent more ships to the moon than we have to explore the ocean's depths...
You can find out more about the amazing National Geographic DeepSea Challenge at their website:
"We know less about the deepest points on our planet than we do about the surface of Mars. The DEEPSEA CHALLENGE team is dedicated to advancing the world’s understanding of our ocean’s vast range of biological and geological phenomena. The historic expedition to the Mariana Trench’s lowest point, the Challenger Deep, which lies 6.83 miles (10.99 kilometers) below the ocean surface, is the first extensive scientific exploration in a manned submersible of the deepest spot on Earth. Piloting the DEEPSEA CHALLENGER, which is outfitted for scientific exploration, James Cameron will conduct tests, collect samples, and document the experience in the high-resolution 3-D for which he’s known globally."
I for one look forward to seeing more footage of the dive and reading about any possible life he might have seen down there! :o)
