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] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
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 ...
This is a list of places on land below mean sea level.. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included.
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
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.
On 1–3 June 2008, during Leg 1, the Japanese robotic deep-sea probe ABISMO (Automatic Bottom Inspection and Sampling Mobile) on dives 11–13 almost reached the bottom about 150 km (93 mi) east of the Challenger Deep: "Unfortunately, we were unable to dive to the sea floor because the legacy primary cable of the Kaiko system was a little bit ...
The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
The Winchcombe meteorite could also hold clues about where the water in the Earth’s vast oceans came from. ... Extra-terrestrial water found for first time in meteorite that fell in UK. Nina Massey.
