(4 years ago)Deep Mariana is the deepest oceanic point on the planet. The half - moon canal is located in the Western Pacific, east of the Mariana Islands near Guam. The region surrounding this pit is important because of many unique environments, including holes that produce liquid sulfur and carbon dioxide, active mud volcanoes, and life [...]
Its depth is difficult to measure from the surface. But in 2010, the U.S. National Ocean and Atmosphere Administration used voice pulses and estimated that “Chalenger Deep” is located at a depth of 10,994 feet.
Last year's assessment of pressure sensors revealed that the deepest point was actually 10,935 feet [10,935 m]. Other estimates vary by less than 100 feet [305 m]. The ocean's second most intense point is also found in the Mariana Gropa.
The Mermaid “The depth of the Mermaid” is 200 kilometers east of “Chalenger Deep”, again with an extraordinary opening of 10,809 feet. As compared with Mount Everest, there is an altitude of 8,848 feet [8,848 m] above sea level. So the deepest part of Gropa Mariana is 2,147 meters deeper than the highest mountain in the world today.
The pit is 2,42km long, and has an average width of just 69km. Because Guam is a United States territory and 15 The Northern Mariana Islands are governed by a US Commonwealth, it is the US that has jurisdiction over Gropa Mariana.
In 2009, time president George W. Bush signed the creation of the National Marine Monument of Gropa Mariana, which created a protected marine reserve of about 506,000 km2, consisting of the seabed and the waters surrounding the remote islands.
The monument includes most of Gropa Mariana, 21 underwater volcanoes, and areas around the 3 islands. Experts say Gropa Mariana was created by the process taking place in a production zone, where two large ocean crust plates, known as tectonic plates, crash.
In an area of subsurgeon, one part of the ocean crust is pushed into the other, dipped in the mantle of the Earth - the layer beneath the earth's crust. Where the two parts of the crust cross, a deep channel forms. In a specific case, the Pacific Ocean's crust is bending under the tribe of the Philippines.
The Pacific Cori is about 180 million years old. Meanwhile, the Philippines tablet is younger and smaller than that of the Pacific. The water pressure at the bottom of the hole is over 703 pounds per square meter. So more than 1,000 times more than you expect on the ocean surface.
A chain of volcanoes rising above ocean waves to form the Mariana Islands makes up the semi - moon bow of Gropa Mariana. Along with the islands are many strange underwater volcanoes. For example, the Eifuk underwater volcano extracts liquid dioxide from hydrothermal sources similar to the chimneys of residential homes.
The liquid from these chimneys has a temperature of 103 degrees Celsius. Recent scientific expeditions have revealed amazingly varied species even in these environmental environments.
Animals living in the deepest parts of Gropa Mariana survive in total darkness and under extreme pressure, says Natasa Gallo, an expert at the Oceanography Institute who has studied video footage from the expedition of renowned director James Cameron in 2012 in the pit's depths.
The food at Marianne's Deep is extremely limited because the deep throat is far from the earth. Earth plant material rarely finds its way to the bottom of the pit, says Gallo, and the dead plankton that sinks beneath the surface, must sink thousands of feet to reach “Chalenger Deep”.
Meanwhile, some microbes rely on their existence on chemicals, such as methane or sulfur, while other creatures feed on marine species that are below them in the food chain. Three of the most common organisms at the Gropa foot are xenofiofors, amphipods, and small sea cucumbers (holothurians).
Meanwhile, one of the principal predators in this area is a fish with a frightening view. Sadly, ocean deeps can also serve as a basket for the many remains that are sunken at sea.
In a study published in 2017 in “Nature Ecology and Evolution”, a team led by scientists at the University of Newcastle in the United Kingdom showed that the chemicals produced by man, and banned since the 1970s, are still hidden in the deepest parts of the ocean.
Gropa Mariana is also not immune to plastic pollution. A 2018 study published in “Geochemical Perspectives” found that microplastics were very common in the waters of Gropa Mariana, showing that these plastics reach out to its deepest points.
