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 Five Deeps Expedition's objective was to thoroughly map and visit the deepest points of all five of the world's oceans by the end of September 2019. [137] On 28 April 2019, explorer Victor Vescovo descended to the "Eastern Pool" of the Challenger Deep in the Deep-Submergence Vehicle Limiting Factor (a Triton 36000/2 model submersible).
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] 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]
This is the Mariana Trench - the deepest point on Earth - found in the Western Pacific Ocean.GARRIOTT: “It is almost 11,000 meters of sea water deep, that is deeper than Mount Everest is high ...
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 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.
In 2010 a UK team from the National Oceanography Centre in Southampton (NOCS), equipped with an autonomously controlled robot submarine, began mapping the full extent of the trench and discovered black smokers on the ocean floor at a depth of 5 km (16,000 ft), the deepest yet found.
The Molloy Deep (also known as the Molloy Hole) is a bathymetric feature in the Fram Strait, within the Greenland Sea [1] east of Greenland and about 160 km (100 mi) west of Svalbard. It is the location of the deepest point in the Arctic Ocean.
