In 2009, the Mariana Trench was established as a US National Monument, Mariana Trench Marine National Monument. [5] One-celled organisms called monothalamea have been found in the trench at a record depth of 10.6 km (35,000 ft; 6.6 mi) below the sea surface by researchers from the Scripps Institution of Oceanography.

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 Scripps Institution of Oceanography deployed the 1,490-ton Navy-owned, civilian-crewed research vessel Thomas Washington (AGOR-10) to the Mariana Trench on several expeditions from 1975 to 1986. The first of these was the Eurydice Expedition, Leg 8 which brought Fisher back to the Challenger Deep's western basin from 28–31 March 1975. [ 33 ]
The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. Yet life finds a way to survive. Very weird life.
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate .
On 23 January 1960, Piccard and Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean. The depth of the descent was measured at 10,916 meters (35,813 feet); later, more accurate, measurements during 1995 found the Mariana Trench to be slightly less deep at 10,911 m (35,797 ft). The descent took four hours.
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]
