Oceans is fraught with a lot of interesting and sometimes even mysterious objects.Mariinsky depression, also known as "Mariana Trench" - a huge gorge at the bottom of the Pacific Ocean.It is the deepest place on Earth.Its total length is 1.5 km.
By its geometric profile it resembles a Latin letter V. The width of the bottom part - from a half to five kilometers.The entire bottom portion is divided by small ridges into several isolated locations.Depth - almost 11 kilometers!
Near the bottom of the pressure is 108.6 MPa, which is more than a thousand times higher than similar indices of average pressure over the Pacific Ocean.Mariinsky depression itself formed by the movement of two huge tectonic plates on the border where she is.
first attempts to study this amazing place taken command of the English corvette "Challenger", which carried out systematic measurements of the bottom.A huge contribution to the study of the area in question was made by Soviet scientists, and later - their Russian colleagues.
Despite the huge number of experiments Mariinsky depression and to this day remains one of the least understood mysteries of the oceans: many objects in near space investigated better.
In 1958, Soviet scientists have found that at a depth of 7 km there is life.In 1960, the French sent into the cavity its newest bathyscaphe "Trieste".The study included the legendary Picard and Jacques-Yves Cousteau.
But the first strangeness yet documented American expedition.With the vessel "Glomar Challenger" was launched Research "hedgehog".Within an hour after immersion microphones recording was broadcast on the surface noise, suspiciously reminiscent of the work of the saw.
cameras recorded deep in some vague shadows.Scientists do not like the idea that in the Mariana Trench may lose the unique equipment, and therefore initiated an urgent upgrade.
carefully and gradually "hedgehog" was raised for eight hours.It turned out that a durable cobalt-titanium construction pokorezhilo beams and rope of a special steel alloy and at all was sawn in half.Who and how could create such remains a mystery.Stunned scientists published a report about the incident in 1996.It can be found in the newspaper "New York Times".
Can Mariinsky cavity whose depth is amazing, hide in their depths some are so large and powerful beings?Explore similar depth is extremely difficult, because it is capable of incredible pressure to crush the cake any more or less large structures.Prior to 1958, the scientific community believed that at depths exceeding 6 km away, life is impossible in principle.
And it turned out that the water depths in the incredible live pogonophores.This is a type of marine invertebrates, which are characterized by the fact that they live in a remarkable tubes from chitin, feeding on bottom sediments.They are unique in that the life of these creatures and does not need sunlight.But why invertebrates needed to "cut" ropes?Or were not they?
Thus, the Mariinsky depression, photographs which are presented in the article is one of the most amazing places on Earth.
