The BBC's Rebecca Morelle reveals what happens to a polystyrene head as it is subjected to the pressure 1,000m below the waves. Bacteria are able to survive at these depths, feeding off methane and sulfur emitted from the crust, and some organisms will feed on these. Crustal material at the western edge of the Pacific Plate is some of the oldest oceanic crust on earth (up to 170 … The deepest ever fish, recorded over 8,000 meters (26,000 feet) down, which is still unidentified.

With the help of some polystyrene heads, science reporter Rebecca Morelle finds out what happens at the pressure experienced 100m below sea level. At 6,000m down, the trenches are full of surprises, as Alan Jamieson, from Oceanlab at the University of Aberdeen, explains. At extreme depths, the bottom of the Mariana Trench is hidden by total darkness – kilometres out of reach of any light. But we at CGTN will present you the world's first live-streamed diving into the Challenger Deep, as China's Fendouzhe (Striver) submersible reaching down to more than 10,000m deep in the ocean..

Only three explorers have made the epic journey there: 11km (seven miles) down to the bottom of the Pacific Ocean's Mariana Trench. But it would be almost 100 years before humans would descend to the depths, when in 1960 Jacques Piccard and Don Walsh got into the submersible Trieste and started their descent. Normally, these organisms produce calcium carbonate shells, but at the bottom of the Mariana Trench, where the pressure is around 1,000 times greater than at the surface, calcium carbonate dissolves. it is host to thousands of species of invertebrates and fish including such oddities as the Angler Fish (see illustration), so called because it uses a bioluminescent (life light) protrusion to attract its prey. A scientist with China's submersible Fendouzhe's mission on Wednesday released a video footage of the bottom of the Mariana Trench the manned deep-sea vehicle reached in a historic dive. Ghostly white and with broad wing-like fins and an eel-like tail, the unknown species of snailfish was recorded multiple times by cameras sent down to the depths. We have mentioned that the creatures which inhabit the Mariana Trench are all uniquely designed to survive in its extreme environment, but contrary to what one might readily assume, these life forms are not the result of evolution and adaptability - Quite the contrary, they are perhaps the most prehistoric life forms … The Mariana Trench is part of the Izu-Bonin-Mariana subduction system that forms the boundary between two tectonic plates.In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west. Tell students that the Trench is 2,500 kilometers (1,554 miles) long and 70 kilometers (44 miles) wide. Launched in the 1960s Alvin surveyed the wreck of the RMS Titanic and many others.

Share this article: There is no autotrophs in the Mariana Trench because there is no light at the bottom of the trench. A Jellyfish So Surreal That It Looks Unreal Is Discovered on the Enigma Seamount. The Mariana Trench is the deepest, darkest portion of the ocean. Able to survive in the boiling hot pools of Yellowstone and the sulfur rich springs of the Danakil Depression, it might therefore come as no surprise to find them thriving close to 11,000 meters (36,000 feet) below the ocean's surface. Researchers in the US copy bird and bat wings to build a drone that can rebound and recover from mid-air collisions.

Humans have been to the deepest place in ocean before – many times actually. This fearsome predator has a lure above its mouth that flickers with bioluminescent light. Image in text: The bioluminescent dargonfish uses its ability to produce light to attract prey. The deepest point of the trench was first discovered during the expedition of the Challenger in 1875, which recorded using drag lines a maximum depth at the time of around 8,184 meters (26,850 feet), towards the southern end of the canyon. Some creatures simply try and be avoided, which normally means either becoming translucent or red, because this absorbs any blue light that has managed to make its way down to the depths.

They may look as clunky as a suit of armour but some atmospheric diving suits (ADS) can enable people to reach depths of up to 600-700m. Icy cold, pitch black and with crushing pressures - the deepest part of the ocean is one of the most hostile places on the planet. Source: Sputnik, CCTV, Daily Mail. In the deepest ocean, scavengers called amphipods dominate, as Alan Jamieson, from Oceanlab at the University of Aberdeen, explains. Large males can weigh as much as four tonnes and live mainly on a diet of fish and squid. If left unchecked, it would cause the membranes to crack and break, so in order to get around this, deep sea creatures have lots of unsaturated fat in their membranes, which help to keep them fluid.
