Scientists may have discovered the largest water reservoir in the world
A water tank three times greater than the total volume of Earth's oceans may have been discovered under the United States, 700 km depth. The discovery was published last week in the journal Science.The article was written by American investigators, led by Geophysicist Steve Jacobsen, and Northestern University by Brandon Schmandt, seismologist at the University of New Mexico.The water found is not in liquid form, but magma wells were found, which may indicate the presence of water. During the investigation the laboratory experiments were used to Jacobsen, where the rock layers studied the Geophysicist of the planet under simulated high pressure, similar to the 700 km depth, together with comments made by seismologist seismic activity data that were collected under the USArray project, a network of seismographs throughout the American territory, referred to Treehugger.Based on investigations, scientists believe the water is stored in the molecular structure of minerals inside the Rocky mantle, in the form of the mineral itself, created by pressure and heat inside of the mantle. In this layer there is a terrestrial ringwoodite, a mineral that has water in its composition which, according to scientific articles published earlier this year, allows to infer the existence of a reservoir of water in the Earth's mantle equivalent to the water of the oceans.Researchers believe that water exists on the planet's surface might have arrival at great depths through the tectonic plates. During the investigation, they found evidence of an extensive melting underneath the North American territory, close to the depth at which can be found the mineral. The depth is this fusion of materials of the Earth's interior is the one that presents the best temperature and pressure so that the water can leave the ringwoodite, a phenomenon that scientists compare to sweating.Currently, only there is evidence of the existence of ringwoodite in the United States, having the presence of the mineral in other parts of the Earth to be confirmed yet.Foto: Wikimedia Commons
