Scientists previously discovered that water is stored inside mantle rock in a sponge-like state, which isn’t a liquid, solid or a gas, but instead a fourth state. The scientific paper titled ‘Dehydration melting at the top of the lower mantle’ was published in 2014 and laid out the findings. "The ringwoodite is like a sponge, soaking up water, there is something very special about the crystal structure of ringwoodite that allows it to attract hydrogen and trap water," said geophysicist Steve Jacobsen at the time. "This mineral can contain a lot of water under conditions of the deep mantle,” added...

Using data from NASA's InSight lander - which carried out a four-year-long mission that ended in 2022 - researchers say the amount of water underground could cover all of Mars with between one to two kilometres of water.

It feels like there have been staggering science stories emerging every other day recently... First, there was the discovery of a terrifying black hole pointing right at us, then there was a huge hole found in the sun and a missing continent found after going missing for 375 years. Now, people are only just realising that there’s a massive ocean hidden under the Earth’s crust. It turns out there’s a huge supply of water 400 miles underground stored in rock known as 'ringwoodite'. ...

The scientists discovered evidence of water hundreds of kilometers deep. An international research team led by a Goethe University professor analyzes diamond inclusions. The boundary layer between the upper and lower mantles of the Earth is known as the transition zone (TZ). It is located between 410 and 660 kilometers (between 255 and 410 miles) under the surface. The olive-green mineral olivine, commonly known as peridot, which makes up around 70% of the Earth’s upper mantle, changes its crystalline structure at the extreme pressure of up to 23,000 bar in the TZ. At a depth of around 410 kilometers (255...

As Earth's tectonic plates dive beneath one another, they drag three times as much water into the planet's interior as previously thought. Those are the results of a new paper published today (Nov. 14) in the journal Nature. Using the natural seismic rumblings of the earthquake-prone subduction zone at the Marianas trench, where the Pacific plate is sliding beneath the Philippine plate, researchers were able to estimate how much water gets incorporated into the rocks that dive deep below the surface. The find has major ramifications for understanding Earth's deep water cycle, wrote marine geology and geophysics researcher Donna Shillington...

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...

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...

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....

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.

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 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...

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.

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....
