Description: Deepest part and place of the world's oceans. Mariana Trench and Ridge, with ridge islands and Challenger Deep. The Challenger Deep is the deepest surveyed point in the oceans, with a depth of about 11000 metres (about 36000 feet). The exact depth is unknown. The trench forms the boundary between two tectonic plates, where the Pacific Plate is subducted beneath the small Mariana Plate. The bottom of the trench is further below sea level than Mount Everest is above it. At the bottom, at more than 10000m/32810 feet, the water column above exceed a pressure of 1000 atmospheres, 1000 kg/sq cm, 100 MPa, over one thousand times the standard atmospheric pressure at sea level. The creatures that could live at these depths are few, but some fish like the Angler fish or other deep sea fishes have been spotted in these waters. Organisms like foraminifera, single-celled protists that construct shells have been discovered near or at the bottom.
About the GE tour: Take a tour along the islands popping up on the Mariana Ridge as tectonic plates moves and underwater volcanoes reach the pacific sea surface. Dive thousands of feets and meters below surface in the Mariana trench and swim on to the reef of the islands. Take a dip and a view of the Challenger Deep with info on deep sea fish and organisms, the submarine diving to the bottom and the original spotting of 'the bottom of the world'. Enjoy.
