Because the depth is so deep and light can't reach the bottom, water is significantly colder especially down at the bottom. No other survey has found fish deeper than 8,145m and the Mariana Trench reaches down to almost 11km. This also contributes to its extreme depth. There are many trenches in the ocean, but because of the location of this trench, it is the deepest. Until now, only two people have successfully made it … In fact, more people have gone to outer space than explored the trench’s depths. The Trench sits like a crescent-shaped dent in the floor of the Pacific Ocean, extending over 1500 miles long with an average width of around 43 miles and a depth of almost 7 miles (or just under 36,201 feet).

In 2009, President George W. Bush established the Mariana Trench Marine National Monument, … The bottom of the trench is cloaked by perpetual darkness, and the waters are at near-freezing temperatures. While the trench and areas like it haven't been fully explored, we know that there are organisms that can survive at this depth — including bacteria, microorganisms, protists, foraminifera, xenophyophores, shrimp-like amphipods, and possibly even some fish. These soft-sediments are mostly made of small particles of silt and clay, also known as “mud”. It is some 1,580 miles long and at its deepest point, ‘Challenger Deep’ stretches down 6.825 miles. Kennedy, Jennifer. Other organisms found at extreme depths include foraminifera. "What Is the Mariana Trench and Where Is It?" Deep-sea organisms also have a lot of piezolytes in their cells that bind to water molecules and prevent the water from being forced into their proteins and distorting them. At the very bottom, he found colorful rocky structures, weird critters and the ever-pervasive mark of humankind — plastic.

China livestreamed footage of its new manned submersible parked at the bottom of the Mariana Trench on Friday, part of a historic mission into the deepest underwater valley on the planet. However, the pair was unable to capture any photographs due to the disturbed silt. Below this point water cools more slowly. Deep-sea creatures such as hagfish feed on the carcasses while bone worms consume the bones. Lovett, Richard A. Water temperature at the bottom of the Mariana Trench ranges from 1 to 4 °C (34 to 39 °F). He went with Mr Vescovo … At the bottom of the Mariana Trench, the oxygen ‘only’ penetrates one metre down, which suggests that there is a relatively high bacterial activity,” says Glud. Exploration Of The Mariana Trench HMS Challenger, the ship from which the first depth readings of the Challenger Deep were taken. "Racing to the Bottom: Exploring the Deepest Point on Earth." The dive to the ocean’s deepest point turned up some surprises. Jackson, Nicholas. To survive the cold and the extreme pressure of the ocean trenches, the organisms have membranes that have unsaturated fats that remain liquid at such conditions and keep the membrane loose. When Don Walsh and Jacques Piccard made the first expedition to the bottom in 1960, they reported seeing a flatfish but they didn’t take photographs, and other marine biologists now think this was probably a sea cucumber. This temperature could be the reason why there are so few animals seen in there, however, those that are seen thrive in colder temperatures. In this system, the western edge of one plate, the Pacific Plate, is subducted beneath the smaller Mariana Plate that lies to the west. LiveScience, Future US, Inc., December 6, 2017, New York, NY.
