The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands.
The Mariana Trench is part of the Izu-Bonin-Mariana subduction system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west.
More than ten years later, when the 24 March 1995 robotic exploration of deep sea. Keiko, Japan, destroyed the statistics survey without the use of the deepest human in the world. When it went down to the bottom of ocean depths. And record the depth at 10.911 meters. It is believed that a number close to reality largest measurement to exploration ship developed by the center for marine science and technology of Japan. (JAMSTEC) and can dive to, 6000 meters. Unfortunately, Keiko lost at sea on March 29 2003 after secondary cable of one lacks because of typhoon is approaching to . From then until now. No devices explore any dive deep at the same level as Keiko. And still no submarines with human which one. The statistics into the deep sea like triple . To the deep sea creatures. The data analysis of the marine sediment samples collected Kaiko found in the abyss of ocean Challenger deep A single cell organisms in depth, 10 900 m. The creatures found in the Challenger deep, almost all. A single cell, the plankton foraminifera
