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 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]
The Mariana Trench is named after the nearby Mariana Islands, which are named Las Marianas in honor of Spanish Queen Mariana of Austria. The islands are part of the island arc that is formed on an over-riding plate, called the Mariana Plate (also named for the islands), on the western side of the trench.
In 1984, the Japanese survey vessel Takuyō (拓洋) collected data from the Mariana Trench using a narrow, multi-beam echo sounder; it reported a maximum depth of 10,924 metres (35,840 ft), also reported as 10,920 10 m (35,827 33 ft; 5,971.1 5.5 fathoms).[15] Remotely Operated Vehicle KAIKO reached the deepest area of the Mariana Trench and made the deepest diving record of 10,911 m (35,797 ft; 5,966 fathoms) on 24 March 1995.[16]
In July 2015, members of the National Oceanic and Atmospheric Administration, Oregon State University, and the Coast Guard submerged a hydrophone into the deepest part of the Mariana Trench, the Challenger Deep, never having previously deployed one past a mile. The titanium-shelled hydrophone was designed to withstand the immense pressure 7 mi (37,000 ft; 6,200 fathoms; 11,000 m) under.[31] Although researchers were unable to retrieve the hydrophone until November, the data capacity was full within the first 23 days. After months of analyzing the sounds, the experts were surprised to pick up natural sounds like earthquakes, typhoons, baleen whales, and machine-made sounds such as boats.[32] Due to the mission's success, the researchers announced plans to deploy a second hydrophone in 2017 for an extended period of time.
The average depth of the ocean is about 3,682 meters (12,080 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep. It is named after the HMS Challenger, whose crew first sounded the depths of the trench in 1875.
Thousands have climbed Mount Everest, and a handful of people have walked on the moon. But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner.
Dive Mates Filmmaker James Cameron, left, and Don Walsh meet by the Trieste at the National Museum of the U.S. Navy in Washington, June 10, 2013. Walsh piloted the Trieste, a deep-diving research vessel, to the deepest-known part of the earth's oceans, the Challenger Deep in the Marianas Trench near Guam on Jan. 23, 1960. Cameron was the third person to reach the Challenger Deep, on March 26, 2012, when he piloted the Deepsea Challenger.

A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench. Scientists found it by looking through the Deep-Sea Debris Database, a collection of photos and videos taken from 5,010 dives over the past 30 years that was recently made public.
Of the classifiable debris logged in the database, plastic was the most prevalent, and plastic bags in particular made up the greatest source of plastic trash. Other debris came from material like rubber, metal, wood, and cloth, and some is yet to be classified.
Last February, a separate study showed that the Mariana Trench has higher levels of overall pollution in certain regions than some of the most polluted rivers in China. The study's authors theorized that the chemical pollutants in the trench may have come in part from the breakdown of plastic in the water column.
I'd probably get it in place using a rocket. Ballistic flight ending approximately at the right place, then splash landing with sufficient number of parachutes. Then decouple all chutes and other attached buoyant parts and go down.
it took alot of anchors to weight it down enough to sink. Coming back up is more problematic as you experienced. Shot out of the water, then destroyed on impacting the water again. I looked at the KAS source, looks like you can make any part non-bouyant by adding the anchor module to it, provided you have KAS. The biggest drawback is lack of camera control underwater, as the camera tries hard to float back up to the surface. Can use the anchor parts to get to the bottom before using engines to navigate along the bottom.
The hadal zone, mostly comprising of deep trenches and constituting of the deepest part of the world's oceans, represents the least explored habitat but one of the last frontiers on our planet. The present scientific understanding of the hadal environment is still relatively rudimentary, particularly in comparison with that of shallower marine environments. In the last 30 years, continuous efforts have been launched in deepening our knowledge regarding the ecology of the hadal trench. However, the geological and environmental processes that potentially affect the sedimentary, geochemical and biological processes in hadal trenches have received less attention. Here, we review recent advances in the geology, biology, and environment of hadal trenches and offer a perspective of the hadal science involved therein. For the first time, we release high-definition images taken by a new full-ocean-depth manned submersible Fendouzhe that reveal novel species with an unexpectedly high density, outcrops of mantle and basaltic rocks, and anthropogenic pollutants at the deepest point of the world's ocean. We advocate that the hydration of the hadal lithosphere is a driving force that influences a variety of sedimentary, geochemical, and biological processes in the hadal trench. Hadal lithosphere might host the Earth's deepest subsurface microbial ecosystem. Future research, combined with technological advances and international cooperation, should focus on establishing the intrinsic linkage of the geology, biology, and environment of the hadal trenches.
The marine pelagic zone situated > 200 m below the sea level (bls) is the largest marine subsystem, comprising more than two-thirds of the oceanic volume. At the same time, it is one of the least explored ecosystems on Earth. Few large-scale environmental genomics studies have been undertaken to examine the phylogenetic diversity and functional gene repertoire of planktonic microbes present in mesopelagic and bathypelagic environments. Here, we present the description of the deep-sea microbial community thriving at > 4900 m depth in Matapan-Vavilov Deep (MVD). This canyon is the deepest site of Mediterranean Sea, with a deepest point located at approximately 5270 m, 56 km SW of city Pylos (Greece) in the Ionian Sea (3634.00N, 2107.44E). Comparative analysis of whole-metagenomic data revealed that unlike other deep-sea metagenomes, the prokaryotic diversity in MVD was extremely poor. The decline in the dark primary production rates, measured at 4908 m depth, was coincident with overwhelming dominance of copiotrophic Alteromonas macleodii'deep-ecotype' AltDE at the expense of other prokaryotes including those potentially involved in both autotrophic and anaplerotic CO(2) fixation. We also demonstrate the occurrence in deep-sea metagenomes of several clustered regularly interspaced short palindromic repeats systems.

Going deeper still and the things start to get even more extreme. The deepest diving mammal, the Cuvier's beaked whale, taps out at around 2,964 metres, and by 4,267 metres you reach the average depth of the world's oceans.
Some parts of the seafloor are ripped open, huge tears plunging ever deeper into the Earth. One of these canyons, stretching north to south for 2,500 kilometres in the western Pacific, is the Mariana Trench.
The deepest point of the Trench is the Challenger Deep, so called as it was first measured during the Challenger expedition in 1875. Using nothing but a weighted rope, they recorded a depth of 8,184 metres, which is incidentally almost exactly the same depth that the deepest known vertebrate has been recorded after a snailfish was filmed at 8,178 metres in 2017.
It would not be until the 1950s that the generally accepted deepest depth of around 10,900 metres would be recorded, although there are a few unrepeated measurements of over 11,000 metres. At this depth the temperature inside a submersible is below freezing, while the sheer weight of water above exerts an unfathomable pressure equivalent to eight tons per square inch, or more than 1,000 times the pressure we experience at sea level.
Not only is this the deepest anyone has ever gone, but Kathy became the first woman ever to go down into the Challenger Deep. In the process of this, she is now the only person ever to have walked in space and descended to the deepest point in the oceans.
