  • Experts discover Life Forms beneath Mantle of Ocean Floor

The experts have discovered life forms beneath the mantle rock of the ocean floor. This proves that life is a hardy thing that can thrive in the most inhospitable of conditions.

Life is such a tenacious and tough entity that it can withstand harrowing situations. A group of scientists recently found that life exists on samples of mantle rock beneath the ocean floor.

Another team tried to do the same thing but failed at the endeavor. This bunch however was successful. They went on a 47 day expedition to the Atlantic Massif. This is 10 miles in width. And it is 14,000 feet in height and lies at the base of the Atlantic Ocean.

Rock samples were gathered from the site. And they show signs of life which is a miracle of sorts. The basic goal of the expedition was to find out how rocks from within the mantle extrude into the exterior and how these rocks interact with the sea water.

Signs of hydrogen and methane were found during the drilling process. Everybody knows that these gases are feeding material for bacteria which then grow and form new cells afterwards.

Rocks and gases on other planets are similar which again lends credence to the hypothesis that they might hold life forms in their bosom. By studying life under such difficult conditions, it is a single step towards postulating that it exists on other seemingly desolate planets.

New studies are being made by the team in order to corroborate its findings. Also clues will be found regarding the early life forms on our own planet.

These life forms do not need sunlight to thrive, which is strange to say the least. And they are carbon-based. How carbon reacts with the high pressure conditions underwater remains an unknown fact.

The very evidence of life forms existing so deep beneath the ocean floor is a mind-boggling thought in itself. It shows the myopia of our so-called latest scientific knowledge.

There is a lot that we don’t know about and a great deal remains to be discovered. The space between the crust and the mantle is termed the seismic boundary.

Seawater filters into the cracks in the rocks beneath giving rise to a material called Serpentinite. This in turn generates the hydrogen and methane and so the bacteria start flourishing.

The carbon cycle that operates in such extreme depths is unique too. More research is currently being carried out by the team of experts.
