A huge underground ecosystem containing billions of microorganisms



A team of scientists found Associate in Nursing eco-system beneath the bottom that’s doubly as massive because the Pacific Ocean.

It seems that the Earth is far more lively than we can imagine. This is also proved by the so-called deep life studies that study the depth of the Earth and its composition.

Thus, in the latest study, conducted by an international team of scientists from the Deep Carbon Observatory project, regardless of extreme temperature, darkness, strong pressure, and limited resources – the underground biosphere consists of between 15 and 23 billion tons of microorganisms.

Researchers who presented the results of the study in mid-December at a regular annual meeting of the American Geophysical Union say that the diversity of underground species can be compared to Amazon or Galapagos, but, unlike those places, its sub-areas should be further investigated.

“It’s like finding a whole life-reservoir on Earth,” said Karen Lloyd of the University of Tennessee, Knoxville.

“We are constantly discovering new types of life. Many more organisms live in the Earth than on its surface, “Lloyd added.

The team of researchers took samples of wells well over five kilometers deep, as well as from underwater wells to construct ecosystem models and estimate how much carbon of organic origin contains the interior of the Earth. The results show that 70 percent of earth bacteria are located below its surface.

Also, organisms were discovered at 2.5 km. below the surface that has been found to live there for millions of years, regardless of solar energy. Instead, methanogenic arches have found a way to create methane, which they use to replace or repair certain parts of the body.

“The strangest factor on behalf of me is that some organisms will exist for millennia. They are metabolically active, but are stalled, with less energy than we thought it needed to sustain life, “Lloyd said.

The underground biosphere is conditioned by geology and geography, and their total volume is estimated to be over 2 billion km cubic meters – and is expected to increase in the future.

Scientists are trying to establish the boundary through which there is no life – but it turns out that, the deeper they dig, they find more organisms. The current maximum is 122 degrees, but it is believed that the record will be contested with new surveys with more precise and more sophisticated instruments.
