The Mariana Trench is a deep point in the ocean and one of the largest crescent-shaped trenches on the surface of the Earth. It contains the only known ventilation point where liquid sulfur and carbon dioxide from the vents inflow, an important source of oxygen to which marine life can adapt.<\/p>\n\n\n\n
Depth is difficult to measure from the surface, and modern estimates vary, but the deepest part of the Mariana Trench is as deep as Everest is high. The Sirena Deep, which is at a depth of about 2,500 meters, is 50 kilometres deep and has bruises. Mount Everest is located at an altitude of 3,600 meters, which means that the deeper part, the Mariana Islands, is about as deep as the depth at which Everest was once high, or about 1,200 meters.<\/p>\n\n\n\n
The Rift is located in the area where the Pacific Plate and the Philippine Plate, as well as the Atlantic and Indian Oceans, meet. To create the Mariana Trench, Pacific plates submerged, releasing water trapped between the plates and exploding upward, creating islands and volcanoes. The Pacific Plate then dipped under the Philippines, while the Philippine Plate was partially swept away. South – East of the Mariana Islands are the islands of Guam, Saipan, Tinian and the U.S. Virgin Islands, all of which have a total area of about 1.5 million square kilometres.<\/p>\n\n\n\n
Scientifically speaking, the deepest part of the ocean is defined as a point that can be reached and defined as a depth of at least 1,000 meters. The ocean itself is deep, but in some cases down to several kilometres. The deepest point in the oceans and seas that surround our continent is about 3.5 km, and some parts are up to 5 km deep. The bottom of a deep sea trench known as the hadal zone is a deep trench created by shifts in tectonic plates. The Mariana Trench is used by submarines as a north-south passage because it is part of the long trench system that circles the Pacific Ocean and connects Japan with the Kuril Trenches.<\/p>\n\n\n\n
Pressure in the deepest part of the Mariana Trench is up to 8 tons per square inch and is about 300 meters deeper than the continental shelf. There would be no summit if Mount Everest were put on the bottom of the Mariana Trench. He told them the animation reflects the actual digital data, which is measurements of water depth. There is an average depth of about 1,000 meters in the ocean, although there are some that are nearly 7 miles long.<\/p>\n\n\n\n
Retired naval officer Victor Vescovo piloted one of his submarines to make the deepest dive on record. The Mariana Trench Dive was part of a series of dives known as the Five Deep Expedition, which visited the deepest points of the five oceans. It was the first deep-water dive by a U.S. Navy ship in more than a century and the largest ever. Vescovo, who funded the mission, and his crew had already completed dives in the Indian, Atlantic and Southern Oceans. Recently, the first year of filming has seen the release of the documentary “The Abyss” by cinematographer David Cameron.<\/p>\n\n\n\n
While thousands of climbers have successfully climbed Mount Everest, the highest point on earth, only two people have ever descended into the depths of Challenger Deep, a chasm in the ocean between the Pacific and Indian Oceans. The Challenger Deep is the gap between tectonic plates that extends 1,500 miles into the western Pacific Ocean and is considered the deepest in all the world’s oceans. It was first measured in 1875 by the first oceanographer Sir Thomas Jefferson, who laid the foundations for modern science and oceanography.<\/p>\n\n\n\n
The deepest point of the rift, Challenger Deep, is in the Mariana Trench, the deepest part of the ocean between the Pacific and Indian Oceans. At almost 11 kilometres (6 miles) deep, the depth of what lies below the summit of Mount Everest (the highest point on the planet) is about as deep as the trench itself. If you descend from Mount Nepal into the Mariana Trench, your peak would be about 1200 meters below the surface or about 3000 meters deep.<\/p>\n\n\n\n
A new study published today in Nature Geoscience has revealed that an unexpectedly abundant community of bacteria has developed in the trench, with organisms living up to 11 kilometres deep. The international team of researchers, led by Ronnie Glud from the University of Southern Denmark, sent a specially constructed 1,300-pound robot to the bottom of the trenches to study the ultra-deep ecosystem. Although standing is a remarkable depth, the water column on its head exerts twice as much pressure as it normally does on the surface, and immediately crushes you.<\/p>\n","protected":false},"excerpt":{"rendered":"
