Today, Canadian born film maker and National Geographic explorer James Cameron reached the deepest point on earth - Challenger Deep - where he spent approximately 6 hours collecting valuable scientific information in a place only three people have ever visited. So where exactly is this place? The Challenger Deep located in the Pacific Ocean is the deepest point of the Mariana Trench. It is located 10,994 m down, in the dark depths. In order to better illustrate the actual depth of the Mariana Trench, consider the following; if Mount Everest, which is the tallest point on earth at 8,848 meters, were set in the Mariana Trench, there would still be 2,146 meters of water left above it.
As you can imagine - conditions down there are different to what we experience on earth's surface. It's dark and pressures are high - approximately 1,099 times that at the surface. All things to consider when designing Mr. Cameron's state-of-the-art submersible.
