Find the deepest seabed in the world

At the deepest point of the Pacific Ocean is called Mariana's area where life has been discovered. Many bacteria populations live in isolation, making marine biologists surprised to expand the hypothesis of where to live on our planet as well as other planets in the Solar System.

Ronnet Klad, who is in charge of a group of scientists at the University of Southern Denmark, said: "We suspect that microorganisms can be found, but do not expect them to have the same level of development as populations. "The bacteria are so rich. We have to wonder how they can live at such depths."

Remember that living at a depth of 11km, the bacteria are subjected to a very high pressure, no light can illuminate and almost no oxygen. Yet, only taking advantage of organic waste materials under a great abyss, they still live and multiply. In addition, their numbers and activity are 10 times higher than bacterial populations living on flat bottoms in the ocean, where the depth is only 5-6km.

The 'autonomous' living microbial populations under the Mariana basin are detected by robots. This automated research device weighs only 600kg but is a real laboratory. It has the ability to automatically pick up soil samples, analyze the composition of water and perform other scientific operations.

The authors argue that there is a high similarity between these bacteria and the congener that exists in ocean water at satellites Europa and Enceladus - the natural satellites of Jupiter and Saturn.

To study the ocean on these satellites, the researchers plan to build self-acting underwater robots, similar to those used to search for bacteria in the deepest regions of Thailand. Binh Duong.

Previously, it was discovered that bacterial populations live in layers of rock contained in volcanic gases erupted as well as hot groundwater.
