Who lives in a huge dead zone in the middle of the Pacific?
There are places on this planet, which at first glance seem almost lifeless. It is places like permafrost, or the deserts of Antarctica. However, in these areas, literally "boils" life. But there is one such region on the planet - a gigantic dead zone, located in the Pacific Ocean. A very long time it was thought that this part of the world's oceans is almost not inhabited, however it is not so.
What is a dead zone in the Pacific Ocean
These remarkable water are at the heart of the South Pacific circle, the center of which there is a so-called oceanic pole of inaccessibility. It also houses the point of Nemo. This is the point having the greatest distance from any land. Nemo Point is also known as the "graveyard of spaceships", as ships are buried here, the risk of harm to people or nature is minimal.

Despite the fact that the oceanic pole of inaccessibility is known to people long ago, the study of its fauna, scientists engaged in very little. For a long time this place was something of a "marine desert".
Who lives in a huge dead zone
Not long ago, a group of German researchers from the Marine Microbiology Institute of the Max Planck on board FS Sonne ship traveled through the area in order to study of who inhabits the mysterious water. In total, scientists have been 4,350 nautical miles (7,000 kilometers).
"To our surprise, we found a large number of bacteria in the surface waters of the South Pacific. At the same time, they are much smaller when compared to other parts of the Atlantic ", - says one of the researchers, microbiologist Bernhard Fuchs. "This is probably the lowest number of microorganisms when a surface inscribed in ocean waters."
Among the microbes found a team dominated by 20 major species. One of the identified populations that caught the attention of researchers - it AEGEAN-169. Firstly, it was the largest, and secondly, these bacteria are found in surface waters. In this case, previous studies have found them only at a depth of 500 meters.
"This points to an interesting feature of bacteria to adapt. Microorganisms that previously resided in deep water, can now reside in surface waters, adapting to temperature and UV. "- said one of the team members, a microbiologist Greta Reintes.
These samples are also confirmed that the oceanic pole of inaccessibility is a unique habitat where organisms can adapt to extreme physical and chemical conditions. In this case, the relative remoteness and inaccessibility to humans makes these waters among the cleanest in the world, and hence changes in the kinds of them can be fixed in the most natural conditions without influence from our civilization.
