At the bottom of the sea, more than 10,000 feet below us, lies a world very different from ours. The deep seabed ensures that few can fathom the mysteries it contains, as even catching a vision is no easy task! However, man's desire to discover and explore the world is insatiable, and we have developed several ways to study and understand the world beneath us.

A quick look at the deep sea, reveals several little things of history, here and there, as shown in the photographs recently published by the National Survey Seabed Ireland, where scientists have been exploring beneath the waves since 1996. Most pictures are from deep water areas where the sonar-equipped ships can navigate easily. The images show a trench Which is 20 kilometers to 30 meters deep, a possible indication of a geological fault.

There was also broad valleys carved into the seabed during or shortly after the last ice age, more than 10,000 years ago. The sea floor sonar images also showed the large number of submarines sunk Germans.

Farther down, at the bottom of the Pacific Mariana Trench, 36,000 feet below sea level, the life of a vibrant ecosystem never seen before by the likes of man. Scientists have always thought that in the deep ocean, there can be life due to extreme conditions. The immense pressure, oxygen deprivation, darkness and low temperatures of the sea have always been considered to always carry a seafloor ecosystem dominated by bacteria.

However, recent studies have shown that even bacteria dominate the upper ten centimeters of the seafloor, simple organisms known as Archaea take this level, comprising up to 87 percent of the biosphere in deep waters. Contrary to popular belief, despite the extreme conditions, there is a thriving ecosystem in the deep ocean floor, with an estimated 90 million tons of biomass. Researchers believe that about 200 million cubic kilometers of mud below the bottom right the sea is inhabited by microorganisms.

In reaching this conclusion, the researchers investigated sediment samples collected several hundreds of meters seabed below the Atlantic and Pacific. The samples came from research expeditions by the Ocean Drilling Program. Following this new discovery, researchers, Drs. Inagaki and Moron, have clearly outlined his vision for the future. With the strong presence of Archaea in deep-sea ecosystems, which have declared that "the intention to study their lifestyle and metabolism, the strategy for long-term survival, and ecological functions.

They Chikyu used, the world's only riser-equipped research vessel and drilling rig. In presenting and discussing their results, scientists are expected to will be able to obtain a more comprehensive, reliable and accurate picture of the deep sea floor.
These microbes are literally dead to the normal standards, barely with any energy at all. Unlike bacteria, which reproduce rapidly, double Archaea themselves less than once per century.

Scientists I think if there is life on other planets in our solar system, is how are you Archaea, lives an extremely slow pace of life due to similar conditions. Hypothetically, similar organisms may be living in the vents beneath the ice of Europa, or in the frozen water on Mars, so that developing an understanding of the Archaea is vital. Moreover, these microbes can survive for the main effects of the Earth from asteroids or radioactive fallout, which means that the deep-water region is a likely refuge During the extinction event.
