Americans donyrnuli to the bottom the deepest hollow of the World ocean
There was a cucumber?
the American Vudhoulsovsky oceanographic institute (Woods Hole Oceanographic Institution (WHOI), Massachussetts, US.) Has published the information that on May, 31st its deep-operating vehicle Nereus has made immersing around the Mariansky hollow and has reached a bottom in the failure of Challenger located here. The fixed depth has made 10902 metres.
Researchers with pride underline that approximately on the same distance from us planes fly. Only above.
looks - Deep-water hollows practically are not investigated, - one of project heads and the developer of the device Andy Bouen (Andy Bowen) speaks. - And with such robot as Nereus, it is possible to reach any. I am assured that we are waited by surprising opening.
First of all scientists would like to understand, how the dynamic processes occurring at an ocean floor, are connected with global climate change. That such communication exists, they do not doubt. And to clear up it the samples of breed delivered from a failure of Challenger - therefrom where tectonic plates converge will help.
On one of pictures which have extended okeanografy, the girl - the student holds a sea cucumber - a live being about which it is told that it is picked up during immersing Nereus. But it is not specified, from what depth. Leah also the bottom? There are doubts that there someone on a broader scale can live. Even cucumbers. Pressure monstrous, in 1000 times more the atmospheric. Utter darkness. Temperature - almost zero.
On a thin hair
Nereus - the robotised catamaran. A drive electric. Lithium - the ionic accumulators, similar subjects by which usual mobile phones are equipped works from 4 thousand. The maximum speed of the device - about 6 kilometres per hour.
the Robot is equipped by a photo - and videocameras, a hand - the manipulator, sonarom, containers for storage of the collected samples. From the additional equipment - installation for bottom drilling.
With surface Nereus has been connected by the most thin - about human hair - and very easy optical cable. He has allowed to receive images from a bottom in real time. According to researchers, to the robot it is possible to stretch already 40 kilometres of such cable.
During present immersing by means of a cable scientists operated a catamaran. The special sinker has carried away Nereus on a bottom. It has dived, gradually unwinding a cable from the coil. It was at the bottom released from a sinker. And before emersion otstrelil a cable not to get confused in it.
the Samples delivered from a bottom, now study in laboratories. Promise to report on results in the near future. And to show video which have been removed in the deepest place of the Earth.
FROM the HISTORICAL BACKGROUND
the Mariansky hollow is located in the western part of Pacific ocean - on a map is designated by dense dark blue colour. More deeply a place it is not found yet.
Nereus - already the third the deep-operating vehicle which has reached here of a bottom. And the first - for last 11 years. Last time, in 1998, the Japanese device dived into a hollow “ Kajko “. It - in the first - in 1995 - m. Alas, in 2003 “ Kajko “ has sunk: The cable on which it lowered has broken.
At the bottom of the Mariansky hollow there were also people. In total once and very much for a long time - in 1960. Then on a bottom have fallen Frenchman Jacque Pikar and the American Don Uolsh in steel bathysphere Trieste. They have stayed on monstrous depth about 20 minutes.
Exact depth of the Mariansky hollow is unknown. Probably that in separate places it exceeds 11 kilometres. For example, measurements from a board of the Soviet research vessel “ the Hero “ spent in 1957, have shown 11 kilometres and 22 metres.
