The Mariana Trench is the deepest oceanic trench on Earth, located in the western Pacific Ocean, about 200 kilometers (124 mi) east of the Mariana Islands. 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 10,935 ± 6 meters (35,876 ± 20 ft; 5,979.3 ± 3.3 fathoms; 6.7947 ± 0.0037 mi) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. This makes the deepest point of the trench more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. At the bottom of the trench the water column above exerts a pressure of 1,086 bar (15,750 psi), approximately 1,071.8 times…

The Philippine Trench (also called the Philippine Deep, Mindanao Trench, and the Mindanao Deep) is a submarine trench to the east of the Philippines. The trench is located in the Philippine sea of the western North Pacific Ocean and continues NNW-SSE. It has a length of approximately 1,320 kilometres (820 miles) and a width of about 30 km (19 mi) from the center of the Philippine island of Luzon trending southeast to the northern Maluku island of Halmahera in Indonesia. At its deepest point, the trench reaches 10,540 meters (34,580 ft or 5,760 fathoms). Immediately to the north of the Philippine Trench is the East Luzon Trench. They are separated, with their continuity interrupted and displ…

The Challenger Deep is the deepest known point of the seabed of Earth, located in the western Pacific Ocean at the southern end of the Mariana Trench, in the ocean territory of the Federated States of Micronesia. The GEBCO Gazetteer of Undersea Feature Names indicates that the feature is situated at 11°22.4′N 142°35.5′E and has an approximated maximum depth of 5,962 to 6,020 fathoms (10,903 to 11,009 m; 35,772 to 36,120 ft) below sea level. A 2011 study placed the depth at 5,971 ± 5 fathoms (10,920 ± 9 m; 35,826 ± 30 ft) with a 2021 study revising the value to 10,935 ± 6 m (35,876 ± 20 ft) at a 95% confidence level. The depression is named after the British Royal Navy survey ships HMS Chall…

The Tonga Trench is an oceanic trench located in the southwestern Pacific Ocean. It is the deepest trench in the Southern hemisphere and the second deepest on Earth after the Mariana Trench. The fastest plate-tectonic velocity on Earth is occurring at this location, as the Pacific plate is being subducted westward in the trench.

The Puerto Rico Trench is located on the boundary between the North Atlantic Ocean and Caribbean Sea, parallel to and north of Puerto Rico, where the oceanic trench reaches the deepest points in the Atlantic Ocean. The trench is associated with a complex transition from the Lesser Antilles frontal subduction zone between the South American plate and Caribbean plate to the oblique subduction zone and the strike-slip transform fault zone between the North American plate and Caribbean plate, which extends from the Puerto Rico Trench at the Puerto Rico–Virgin Islands microplate through the Cayman Trough at the Gonâve microplate to the Middle America Trench at the Cocos plate. Scientific studies…

The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia. The IBM arc system extends over 2,800 km (1,700 mi) south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sea level. The IBM arc system lies along the eastern margin of the Philippine Sea plate in the Western Pacific Ocean. It is the site of the deepest gash in Earth's solid surface, the Challenger Deep in the Mariana Trench. The IBM arc system formed as a result of subduction of the western Pacific plate. The IBM arc system now subducts mid-Jurassic to Early Cretaceous lithosphere, with…

Limiting Factor, known as Bakunawa since its sale in 2022, and designated Triton 36000/2 by its manufacturer, is a crewed deep-submergence vehicle (DSV) manufactured by Triton Submarines, built for and originally owned and operated (2018–2022) by explorer Victor Vescovo's ocean research firm, Caladan Oceanic, and currently owned and operated by Gabe Newell's Inkfish ocean-exploration research organization. It currently holds the records for the deepest crewed dives in all five oceans. Limiting Factor was commissioned by Victor Vescovo for $37 million and operated by his marine research organization, Caladan Oceanic, between 2018 and 2022. It is commercially certified by DNV for dives to ful…
