After decades of theories and research, the scientists report that has finally found a massive water reservoir in the mantle of the Earth – a vast reservoir that could fill the oceans on Earth three times. This discovery suggests that water the earth’s surface actually came from within, as part of a “cycle of water throughout the Earth,” instead of the prevailing theory of icy comets striking Earth billions of years ago. As always, the more we understand about how the Earth formed and how its multitude of inner layers continue to function, more precisely, we can predict the future. Over time, sea levels, climate change -. These are closely linked to the tectonic activity that churns out endless distance beneath our feet
This new study, written by a number of geophysicists and scientists from the US, leverages data the USArray – an arsenal of hundreds of seismometers located throughout the US they are constantly listening to movements in the mantle and the core of the Earth. After listening for a few years, and carry a lot of complex calculations, researchers believe they have found a huge reservoir of water found in the area transition between the upper and lower mantle – A region occupies between 400 and 660 kilometers (250-410 miles) beneath our feet.
As you can imagine, things are a bit more complex than too low. We are not talking about a kind of reserve of water that can be achieved in the same way as an oil well. The deepest of human well has ever gone is only 12 – halfway through the crust of the Earth – and we had to stop because geothermal drill melted. 660 kilometers is a long, long way down, and stuff happens down there.
Basically, the new theory is that the Earth’s mantle is filled with a mineral called Ringwoodite. We know from experiments here on the surface, under extreme pressure, Ringwoodite water accumulation. Measurements by the USArray indicate that as Ringwoodite convection pushes deeper into the mantle, increased pressure forces the water trapped out (a process known as fusion dehydration). That seems to be the scope of the study’s conclusions. Now they have to try to unite the deep earth geology-with what actually happens on the surface. Earth is an extremely complex machine that usually moves at a very, very slow pace. years of measurements needed to get anything approaching useful data.
With all that said, could have massive repercussions if the findings of this study are accurate. Even if the Ringwoodite contains only about 2.6% water, the volume of the transition zone means that this underground reservoir could contain enough water to refill the ocean three times. I’m not saying that this gives us the perfect excuse to continue our abuse of freshwater reserves on Earth, but it’s definitely something to think about. This also seems to rule the prevailing theory that surface water came to Earth through a lot of icy comets.
Finally, here’s a fun thought it should remind us that the composition and the perfect climate of the Earth is, if you look closely, in miraculous place. One of the researchers, speaking to New Scientist magazine, said that if the water is not stored underground, “would be on the surface of the Earth, and the mountaintops would be the only land poking out.” Perhaps if the formation of the Earth had to be a little different, or if we were marginally closer to the sun, or if a random asteroid did not land here millions of years ago … probably would not be sitting here surfing the web.
