Microbial life beneath the ocean—IODP

The IODP has found microbial life 2,400m under the ocean. The international ocean discovery program discovery of microbes living beneath the seabed off Japan was presented in the Geophysical Union Fall Meeting at America. The samples which were taken from the 2, 446 m of rock under ocean were analyzed for this discovery.

IODP Key discovery

It was revealed that microbial life exists deep under the sea floor in the form of single celled organisms/microbes. They survive in the harsh environment despite of no oxygen, no light, and barely any water and mainly on low calorie diet of hydrocarbons with very limited nutrients, and having very low metabolism.
The expedition made by IODP is the deepest drill in the world and now holds the world record for it. Such microbial were never seen before the discovery of Coast off Japan. These microbes are one of the tiny single celled life forms that lived on earth without light and oxygen. Such discovery of life survival in hostile conditions also sparked hopes for the existing life on other planets also. Scientist said that if the microbes are able to survive in coal fields beneath the ocean can have potential to survive on inhospitable planets also.
Elizabeth Trembath-Reichert, who is part of this research team, said:

We keep looking for life, and we keep finding it, and it keeps surprising us as to what it appears to be capable of.Elizabeth Trembath-Reichert

About IODP Expedition

The International Ocean Discovery Program (IODP) took place at the coast of Japan’s Shimokita Penisula in the northwestern pacific ocean in the year 2012. The drilling was flung from the Behemoth sized ship named Chikyu. It took 1000m to reach the sea floor and as the drill penetrate at the 2,446 m depth, it sets a new record for this kind of marine exploration.

The purpose of this expedition was to find out whether the life exists at extreme depths, with no oxygen and light as well as less nutrients well beyond the seafloor.
