As the ice age ended, glaciers melted. "I think we are finally seeing evidence for a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet. “We knew there was fresh water down there in isolated places, but we did not know the extent or geometry,” said lead author Chloe Gustafson, a PhD candidate at Columbia University’s Lamont-Doherty Earth Observatory, according to Phys.org.

It turns out the subterranean pools stretch for at least 50 miles off the US Atlantic coast, containing vast stores of low-salinity groundwater, about twice the volume of Lake Ontario. On Earth, an ocean is one of the major conventional divisions of the World Ocean.These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The hidden reservoir, apparently locked in a blue crystalline mineral called ringwoodite, may hold three times as much water that exists in all the world’s surface oceans. That rivals the size of even the largest terrestrial aquifers. See more ideas about Abandoned ships, Under the sea, Shipwreck. An ocean is a body of water that composes much of a planet's hydrosphere. The size and extent of the freshwater deposits suggest they are also being fed by modern-day runoff from land—and may exist elsewhere with similar topography.

They found that ringwoodite attracts hydrogen and that it's capable of absorbing water much like a sponge, the Guardian reported. News for the next era, not just the next hour. The researchers think that movement within the mantle spurred a reaction that led the water to merge with the ringwoodite. Thousands of years ago, glaciers covered much of the planet. Massive river deltas flowed out across the continental shelf. The oceans rose, and fresh water was trapped in sediments below the waves. Enjoy! Discovered while drilling for oil offshore in the 1970s, scientists thought these “isolated” pockets of fresh water were a curiosity.

This discovery may help explain where Earth's water supply came from, and how subterranean water affects the shifting of rock in the Earth's outer crust -- a phenomenon scientists call plate tectonics.

It is light and brittle and can break. Kick off each morning with coffee and the Daily Brief (BYO coffee). Oceans receded as water froze in massive sheets of ice blanketing the North American continent. Working with University of New Mexico seismologist Dr. Brandon Schmandt, Jacobsen used seismometers to measure earthquakes and the speed of resulting seismic waves at various depths in the Earth. on Pinterest.

To verify the theory, the team then attempted to replicate the ringwoodite layer in the laboratory. By providing your email, you agree to the Quartz Privacy Policy. So, according to the research, the hidden "ocean" may be trapped in the transition zone between the Earth's upper and lower mantle. That’s still valuable. Hidden 'Ocean' Discovered Deep Underground Near Earth's Core, hidden "ocean" is nestled in the Earth's mantle, looking for this missing deep water for decades, It's good evidence the Earth's water came from within. They may instead prove to be a parched world’s newest source of fresh water. Desalination plants could easily turn that into drinkable water.

©2020 Verizon Media. While some scientists subscribe to the theory that Earth's early water came from comets that came our way, the discovery of the hidden reservoir suggests that the world's water emanated from deep beneath the surface. Discovered while drilling for oil offshore in the 1970s, scientists thought these “isolated” pockets of …

As told in the latest issue of the peer-reviewed journal Scientific Reports, scientists from Columbia University and the Woods Hole Oceanographic Institution spent 10 days on a research ship towing electromagnetic sensors from New Jersey to Massachusetts. The Underwater Photography Guide was able to donate 25% of the proceeds from the competition to these two organizations. "It's good evidence the Earth's water came from within," Jacobsen told New Scientist. Today is National Voter Registration Day! These are the core obsessions that drive our newsroom—defining topics of seismic importance to the global economy.

Part of HuffPost Science. A paper describing the research was published in the journal Science on June 13, 2014. Our emails are made to shine in your inbox, with something fresh every morning, afternoon, and weekend. Quartz is owned by Uzabase, the business intelligence and media company. A new study suggests that a hidden "ocean" is nestled in the Earth's mantle some 400 miles beneath North America. The hidden reservoir, apparently locked in a blue crystalline mineral called ringwoodite, may hold three times as much water that exists in all the world's surface oceans. We may have another "ocean" to add to the world map -- only this one is hidden hundreds of miles beneath our planet's surface.

By measuring the way electromagnetic waves traveled through fresh and saline water, researchers mapped out fresh-water reservoirs for the first time. The deposits begin about 600 ft (183 m) below the seafloor and stretch for hundreds of miles. The underground ocean consists of water trapped within minerals, and it may be the size of all of the Earth’s oceans put together. Ocean Art "Safe Under the Sea" has been a great way to bring people from around the world together to dust off old hard drives, share the beauty of our oceans, and help aid the WHO and CDC Foundation in their fight to improve the health of the planet and its people.

"Geological processes on the Earth’s surface, such as earthquakes or erupting volcanoes, are an expression of what is going on inside the Earth, out of our sight," geophysicist Dr. Steven Jacobsen, an associate professor at Northwestern University, said in a written statement. Scientists have been looking for this missing deep water for decades.". The water is not pure terrestrial fresh water, which contains salt concentrations of less than one part per thousand.

The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. From those readings, the team saw that seismic waves seem to slow down when they hit the layer of ringwoodite in the mantle -- leading them to theorize that the mineral was saturated with liquid. The oceans rose, and fresh water was trapped in sediments below the waves. Toward its edges, it may reach 15 parts per thousand (about half that of seawater).

“It could turn out to be an important resource in other parts of the world.”.
