By June 16, 2014 (NASA) (Source: NASA) In the remote and forested terrain of Juina in western Brazil, an ugly rock with an uglier name surfaced months ago inside a diamond mine. It was a tiny green crystal, all scars and bumps. It “literally look[ed] like [it had] been to hell and back,” one scientist said in March. But despite the provenance, the ringwoodite stone wasn’t scorched — it was, in fact, sopping wet. Providing an unparalleled glimpse into the our planet’s innards, the stone rode a violent volcanic eruption to the surface from 325 miles inside the Earth’s mantle....

The researchers compiled data from the California Division of Oil, Gas and Geothermal Resources, which tracks oil and gas wells around the state. Researchers determined if water had been detected while drilling, and also gathered data about depth, salinity and pressure. After looking at 360 oil and gas fields spread across eight counties, the researchers say that they’ve documented a trove of fresh water just over half the size of Lake Michigan hidden in California’s bedrock 1,000 to nearly 10,000 feet below the surface. This is almost three times more groundwater than what was indicated in previous studies, many conducted...

The blue ball represents all of the earths water. Not that much...

Explanation: How much of planet Earth is made of water? Very little, actually. Although oceans of water cover about 70 percent of Earth's surface, these oceans are shallow compared to the Earth's radius. The above illustration shows what would happen is all of the water on or near the surface of the Earth were bunched up into a ball. The radius of this ball would be only about 700 kilometers, less than half the radius of the Earth's Moon, but slightly larger than Saturn's moon Rhea which, like many moons in our outer Solar System, is mostly water ice. How...

The world's oldest water, which is locked deep within the Earth's crust, is present at a far greater volume than was thought, scientists report. The liquid, some of which is billions of years old, is found many kilometres beneath the ground. Researchers estimate there is about 11m cubic kilometres (2.5m cu miles) of it - more water than all the world's rivers, swamps and lakes put together. The study was presented at the American Geophysical Union Fall Meeting. It has also been published in the journal Nature. The team found that the water was reacting with the rock to release...

A team of researchers revealed evidence of an unknown geochemical pathway used by the Earth to sequester water deep within, releasing small amounts through plate tectonics in a process that feeds our oceans "from within," Ohio State University reported.

First terrestrial discovery of an extremely rare mineral called ringwoodite confirms theory about huge water ‘reservoirs’ 410 to 660 km beneath the surface of our planet, says a team of researchers led by Prof Graham Pearson from the University of Alberta, Canada.

Scientists say rock layer hundreds of miles down holds vast amount of water, opening up new theories on how planet formed After decades of searching scientists have discovered that a vast reservoir of water, enough to fill the Earth’s oceans three times over, may be trapped hundreds of miles beneath the surface, potentially transforming our understanding of how the planet was formed. The water is locked up in a mineral called ringwoodite about 660km (400 miles) beneath the crust of the Earth, researchers say. Geophysicist Steve Jacobsen from Northwestern University in the US co-authored the study published in the journal...

In what could quench the thirst of billions of people in the future, researchers have discovered our planet's largest water reservoir 640 km beneath our feet - bound up in rock deep in the earth's mantle. This water is not in a form familiar to us - it is not liquid, ice or vapour. This fourth form is water trapped inside the molecular structure of the minerals in the mantle rock. Scientists have been looking for this missing deep water for decades," explained geophysicist Steve Jacobsen from Northwestern University.

Scientists Discover Massive Freshwater Reserves Underneath The Ocean Floor Agence France Presse Dec. 5, 2013, 7:22 AM Australian researchers said Thursday they had established the existence of vast freshwater reserves trapped beneath the ocean floor which could sustain future generations as current sources dwindle. Lead author Vincent Post, from Australia's Flinders University, said that an estimated 500,000 cubic kilometres (120,000 cubic miles) of low-salinity water had been found buried beneath the seabed on continental shelves off Australia, China, North America and South Africa. "The volume of this water resource is a hundred times greater than the amount we've extracted from...

Researchers at Northwestern University have found evidence for a massive reservoir of water deep within the Earth's mantle. The reservoir, which is said to be three times the volume of the oceans on the surface, is contained within highly-pressurized rock known as ringwoodite. The scientists hope that their findings, recently published in the journal Science, can shed light on where Earth's oceans came from. THREE TIMES THE VOLUME OF THE OCEANS ON EARTH'S SURFACE The team, led by mineralogist Steven Jacobsen, used an array of 2000 seismometers to study how seismic waves generated by earthquakes move through the Earth's interior....

Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth’s oceans to the upper mantle than previously thought.Water is carried mantle by deep sea fault zones which penetrate the oceanic plate as it bends into the subduction zone.  Subduction, where an oceanic tectonic plate is forced beneath another plate, causes large earthquakes such as the recent Tohoku earthquake, as well as many earthquakes that occur hundreds of kilometers below the Earth’s surface.Seismic modellingSeismologists at Liverpool have estimated that over the age of the Earth, the Japan subduction...

CORVALLIS, Ore. – A team of scientists from Oregon State University has created the first global three-dimensional map of electrical conductivity in the Earth's mantle and their model suggests that that enhanced conductivity in certain areas of the mantle may signal the presence of water. What is most notable, the scientists say, is those areas of high conductivity coincide with subduction zones – where tectonic plates are being subducted beneath the Earth's crust. Subducting plates are comparatively colder than surrounding mantle materials and thus should be less conductive. The answer, the researchers suggest, may be that conductivity in those areas...

Scientists scanning the deep interior of Earth have found evidence of a vast water reservoir beneath eastern Asia that is at least the volume of the Arctic Ocean. The discovery marks the first time such a large body of water has found in the planet’s deep mantle. The finding, made by Michael Wysession, a seismologist at Washington State University in St. Louis, and his former graduate student Jesse Lawrence, now at the University of California, San Diego, will be detailed in a forthcoming monograph to be published by the American Geophysical Union. Looking down deep The pair analyzed more than...

Huge Underground "Ocean" Found Beneath Asia Richard A. Lovett for National Geographic News February 27, 2007 A giant blob of water the size of the Arctic Ocean has been discovered hundreds of miles beneath eastern Asia, scientists report. Researchers found the underground "ocean" while scanning seismic waves as they passed through Earth's interior. But nobody will be exploring this sea by submarine. The water is locked in moisture-containing rocks 400 to 800 miles (700 to 1,400 kilometers) beneath the surface. "I've gotten all sorts of emails asking if this is the water that burst out in Noah's flood," said the...
