With about 11,000 meters deep, the Challenger Deep in the Mariana Trench is the deepest surveyed point in the Ocean. At this depth, the pressure is approximately 1,095 times that at the surface, or over 16,000 pounds per square inch.
The Challenger Deep is the deepest surveyed point in the oceans, with a depth of about 11,000 metres (about 36,000 feet). It lies in the Mariana Islands group at the southern end of the Mariana Trench. The closest land is Fais Island, one of the outer islands of Yap, 289 km southwest and Guam 306 km to the northeast. The point is named after the British Royal Navy survey ship HMS Challenger, which first discovered the trench in 1872.
