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.
In 1993, GEBCO recognized the 10,920 ± 10 m (35,827 ± 33 ft) report as the deepest depth of the world's oceans. [58] Technological advances such as improved multi-beam sonar would be the driving force in uncovering the mysteries of the Challenger Deep into the future.
Victor Vescovo has made the most dives to Challenger Deep; by August 2022 he had made eleven dives to the Eastern pool, two to the Western pool, and two to the Central pool for a total of 15 dives. [6] [7] The following is a list of individuals who have descended to Challenger Deep in the Federated States of Micronesia. These individuals will ...
The Pacific Ocean's mean depth is 4,000 meters (13,000 feet). [3] The 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]
Kelly Walsh dived 11,000m under the ocean to Challenger Deep, 60 years after his father Don Walsh made the journey. He tells Bevan Hurley he’s watched the Titan rescue in ‘horror and sadness’
This list contains all lakes whose maximum depth is reliably known to exceed 400 metres (1,300 ft) Geologically, the Caspian Sea, like the Black and Mediterranean seas, is a remnant of the ancient Tethys Ocean. The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt ...
The deepest point below the ocean's atmospheric surface is Challenger Deep, at the bottom of the Mariana Trench, 11,034 m (36,201 ft) below sea level. [28] Jacques Piccard and U.S. Navy Lieutenant Don Walsh first reached Challenger Deep in 1960 aboard the bathyscaphe Trieste, followed by filmmaker James Cameron in 2012 aboard Deepsea Challenger.
The cumulative area occupied by the 46 individual hadal habitats worldwide is less than 0.25% of the world's seafloor, yet trenches account for over 40% of the ocean's depth range. [3] Most hadal habitat is found in the Pacific Ocean, the deepest of the conventional oceanic divisions. [3]
