The maximum known depth is 10,984 ± 25 metres (36,037 ± 82 ft; 6,006 ± 14 fathoms; 6.825 ± 0.016 mi) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. [1] The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a]
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
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.
The maximum depth recorded during this record-setting dive was 10,908 metres (35,787 ft). [44] Measured by Cameron, at the moment of touchdown, the depth was 10,898 m (35,756 ft). It was the fourth-ever dive to the Challenger Deep and the second crewed dive (with a maximum recorded depth slightly less than that of Trieste 's 1960 dive). It was ...
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’
The Challenger Deep is located in the Western Pacific Ocean near the island of Guam in the Mariana Trench, the deepest known part of an ocean on Earth, and the deepest known location on Earth. [5] The May 2009 dive by the Nereus achieved a depth of 10,902 metres (35,768 ft), making it the world's deepest-diving vehicle then in operation, and ...
The outer rim of the trench is at a depth of 2,700 m (8,900 ft) and contains about 600 km 2 (230 sq mi) inside the rim, descending to approximately 5,550 m (18,210 ft) at its greatest depth. The basin floor measures about 220 km 2 (85 sq mi) and is the deepest point in the Arctic Ocean.
On 28 April 2019, Vescovo descended nearly 11 km (7 mi) in Limiting Factor to the deepest place in the World – the Challenger Deep in the Pacific Ocean's Mariana Trench. On his first descent, he piloted the DSV Limiting Factor to a depth of 10,928 m (35,853 ft), a world record by 16 m (52 ft). [20]
