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 hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches. The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions. [1][2] The cumulative area occupied by the 46 individual hadal ...
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 ...
The Sirena Deep, originally named the HMRG Deep, was discovered in 1997 [1][2] by a team of scientists from Hawaii. [2] Its directly measured depth of 10,714 m (35,151 ft) is third only to the Challenger Deep and Horizon Deep, currently the deepest known directly measured places in the ocean. [3][4][5] It lies along the Mariana Trench, 200 ...
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 ...
Deepsea Challenger (DCV 1) is a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of the Challenger Deep, the deepest-known point on Earth.On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep.
The deepest part of the deep sea is Mariana Trench located in the western North Pacific. It is also the deepest point of the Earth's crust. It has a maximum depth of about 10.9 km which is deeper than the height of Mount Everest. In 1960, Don Walsh and Jacques Piccard reached the bottom of Mariana Trench in the Trieste bathyscaphe.
