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).
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 ...
The Pacific Ocean's mean depth is 4,000 meters (13,000 feet). [3] 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 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 ...
