The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres (36,037 ± 82 ft ...
On 23 May 2016, the Chinese submersible Haidou-1 dived to a depth of 10,767 m (35,325 ft) at an undisclosed position in the Mariana Trench, making China the third country after Japan (ROV KaikÅ), and the US (HROV Nereus), to deploy a full-ocean-depth ROV. This autonomous and remotely operated vehicle has a design depth of 11,000 m (36,089 ft).
The Marianas Trench Marine National Monument is a United States National Monument created by President George W. Bush by the presidential proclamation no. 8335 [3] on January 6, 2009. [4][5][6][7] The monument includes no dry land area, but protects 95,216 square miles (246,610 km 2) of submerged lands and waters in various places in the ...
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe. In 1960, it became the first crewed vessel to reach the bottom of Challenger Deep in the Mariana Trench, the deepest point in Earth's seabed. [2] The mission was the final goal for Project Nekton, a series of dives conducted by the United States Navy in the Pacific ...
On 23 January 1960, Piccard and Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean. The depth of the descent was measured at 10,916 meters (35,813 feet); later, more accurate, measurements during 1995 found the Mariana Trench to be slightly less deep at 10,911 m (35,797 ft). The descent took four hours.
Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about 50,000 km (31,000 mi) of oceanic trenches worldwide ...
Challenger Deep in the Mariana Trench, located in the northwestern Pacific, is the deepest known point in the world, reaching a depth of 10,928 meters (35,853 feet). [4] The Pacific also contains the deepest point in the Southern Hemisphere, the Horizon Deep in the Tonga Trench, at 10,823 meters (35,509 feet). [5]
The Mariana Islands are the southern part of a submerged mountain range that extends 1,565 miles (2,519 km) from Guam to near Japan. Geographically, the Marianas are part of a larger region called Micronesia, situated between 13° and 21°N latitude and 144° and 146°E longitude. The Mariana Islands have a total land area of 1,008 km 2 (389 sq ...
