Scientists Find Evidence of "Ocean" Hundreds of Miles Below Earth's Surface

There is new evidence of an ocean inside the Earth.

An international team of researchers concluded in a new study published in the journal Nature Geoscience that the boundary between our planet's upper and lower mantle is known as the transition zone.

Our understanding of the Earth's water cycle could be affected by the research.

The researcher at the Institute for Geosciences at Goethe University said in a statement that the transition zone is not a dry sponge. Jules Verne had an idea of an ocean inside the Earth.

It may be extraordinary in total volume, because of the dark and hydrous rock that is present.

Large quantities of water and CO2 can be held in the sediments. It was not clear how much enters the transition zone in the form of hydrous minerals and carbonates, and whether large quantities of water really are stored there.

According to the statement, the transition zone may contain up to six times the amount of water found in all of the oceans combined.

Ringwoodite, an element that forms under high levels of pressure and temperatures in the Earth's mantle, is the most common element in the diamond analyzed. The gem analyzed contained ringwoodite and water.

The latest research adds credence to the theory that the Earth's transition zone holds a lot of water.

"If you only have one sample, it could be a local hydrous region," said Timmerman, who was not part of the study.

There is an ocean in Earth. The water is hundreds of kilometers down.

Scientists are puzzled by two huge mass inside the earth.
