Deepest Part Of The Ocean
The deepest part of the ocean in the World is the Challenger Deep point with a depth of 35,797 ft (10,911 m). Named after the British survey ship Challenger II which discovered it in 1951, Challenger Deep is located in the Pacific Ocean just east off the Philippines coast, at the southern end of the Mariana Trench.
At the deepest point on Earth, pressure is very high with freezing temperatures, making it it an ultimately inhospitable environment. Challenger deep floor also features hot hydrothermal vents with temperatures reaching up to 300° Celsius (572° Fahrenheit). The venting fluid is highly acidic, while the water from the deep ocean is slightly basic.
The latest Challenger Deep descent was in 2009 by a Nereus robotic vehicle. In January 2010, marking the fiftieth anniversary of the first and only manned descent, the X Prize Foundation announced a $10 million prize for the first privately funded craft to make two repeated manned descents.
