I happened on an interesting and very well presented theory that has changed my view of earth's geology.

Retired US Army and Air Force colonel Walt Brown has been developing what he calls the hydroplate theory for a couple of decades now. He postulates that about half of what is now the ocean waters on planet earth was some ten miles underground, when the moon's tidal forces super-heated it, forcing it to erupt through a grand rupture in the earth's granite crust some 5000 years ago. This created the mid-oceanic rifts, flooded the earth in immense rain storms, rose up the higher mountain ranges and sank the Pacific floor, and thanks to the shifting masses on the earth's surface, resulted in a change in the earth's tilt in the following century.

Walt wraps his hydroplate theory in his readings of the Bible, the great flood of the time of Noah, and the Christian Creationist view that the earth was created by God some 6000 years ago.

I choose an entirely different wrapping. I left the church, the Christian faith, and reading the Bible at age 11, and have not looked back. My background since that day has been more materialist and scientific oriented.

I would speculate that there were prior human civilizations that achieved a technical competence and economic scale similar to our present one, and in some ways surpassing. I would speculate that the moon was artificially placed in earth orbit long after the earth formed, and that the earth was created by natural means over a very long period of time (millions or billions of years.)

But, either way, Christian Creationist or Scientific Materialism, once you get past your choice of wrapper, Walt Brown has one damn fine piece of scientific work here. It is logical, cogent, well researched, and provides consistent explanations of many details of the current geological and near-earth astrophysical record that the gradualist and evolutionary "conventional" plate tectonic theory cannot explain or incorrectly predicts.

Perhaps the best introductions to hydroplate theory are in a Youtube video introduction provided by Walt Brown himself and in a derivative work, David Warner Mathisen's The Mathisen Corollary: Connecting a Global Flood with the Mystery of Mankind's Ancient Past (http://www.amazon.com/Mathisen-Corollary-Connecting-Mankinds-Paperback/dp/B00GWR6S2E/).

Here's Walt's Youtube video:

Here's selected early parts of one chapter from The Mathisen Corollary describing the hydroplate theory:

==============



Earlier in the book, we examined the hydroplate theory of Dr. Walt Brown, a graduate of both West Point and MIT and a former professor at the US Air Force Academy.  Dr. Brown begins with one very unconventional assumption – that prior to an ancient cataclysmic global flood, there was salty water trapped in a layer underneath the earth’s crust, under great pressure – and from this single assumption he proceeds to examine the evidence all over the globe which supports his theory that the violent escape of this trapped subterranean water led to the features we see on the earth today.

Dr. Brown’s extensive array of evidence – all of which can be better explained by his theory than by the reigning uniformitarian geological theories, including the widely-accepted theory of plate tectonics – is almost entirely geological in nature.  He does occasionally venture into anthropological evidence, such as when he examines briefly the oral traditions of the Hopi people, but in general his writing is concerned with the physical features of the earth (and the solar system) which support his explanation (and which pose tremendous problems for the currently-dominant paradigm). 

==============

David Warner Mathisen also presents this overview of Walt Brown's hydrotheory on an article on Graham Hancock's website (http://www.grahamhancock.com/forum/MathisenD1.php?p=4):

==============



Dr. Brown’s hydroplate theory begins with one assumption – that there was once a large amount of water trapped under the earth’s surface. This water was under tremendous pressure (due to the weight of the crust above it) and when a rupture took place which enabled it to burst out, the results were catastrophic. The high-pressure water rushed out with tremendous violence, and the crack of the initial rupture spread rapidly in both directions until it encircled the globe and intersected itself again. The force of the escaping water eroded the crust above it and widened the crack on either side as it blasted away earth from the sides of the rupture, mixing massive amounts of sediments into the water that would eventually blanket the earth, and also removing the weight of the crust along the line of the rupture (which now encircled the earth “like the seam of a baseball,” in Dr. Brown’s words). The removal of so much sediment allowed the basement rock that had been below the line of the rupture to spring upwards, and this caused the massive plates that would become our continents (the now-separated pieces of the crust on either side of the rupture) to begin sliding away from the upward-springing seam in either direction, still lubricated by the escaping water beneath.

This upward-springing action on one end of the globe, however, would not just cause an “air bubble” to open up in the center of the earth, of course: instead, it would cause an equal and opposite “downward-sucking” action on the opposite side of the earth. This process created the Pacific basin, which contains geological features consistent with what you will see if you suck the air out of a metal gasoline can, for instance (creating a suction and a collapse), or if you stick your thumb into the side of a ping-pong ball (there wasn’t a thumb pressed into the Pacific because it wasn’t pressed from above, it was pulled from beneath, but the arc-and-cusp shape of the Pacific trenches, and the fact that they lack the mass that they should have if they were indeed formed by one enormous plate subducting below another, indicates that the Pacific was formed by forces with similar vectors). The continents slid towards the Pacific basin and away from the upward-bulging mid-Atlantic ridge, their steep-sided continental shelves still matching the line of the mid-Atlantic ridge, because that was the line of the original rupture, whose upward-jetting water created the vertical sides of those shelves when the water that had been below the continents escaped.

Eventually, friction (as the subterranean water all escaped) or collision caused these sliding “hydroplates” to grind to a violent stop, creating violent buckling and long parallel mountain ridges roughly perpendicular to the direction of travel, just as you would create “mountains” in the front of your car if you drove it at high speed into a concrete wall. Also, along their forward edges especially, friction melted rock and created magma, which is why the “ring of fire” generally outlines the Pacific basin towards which all these plates were sliding. The thickening of the continents due to this buckling caused the waters to begin to rush off into the ocean basins, although in many places it was trapped and lifted to great elevations as the hydroplates came to a stop. Later, when precipitation continued to fill these trapped bodies of water, some of them breached violently, carving features such as the Grand Canyon (the Vale of Kashmir may have been another example, and the Jhelum River may mark its breach). In other parts of the world, where trapped bodies of water received less precipitation, the inland seas sometimes dried up or receded over the centuries (the Great Salt Lake in Utah may be one such example, and Lake Titicaca in the Andes may be another, although it has not dried up completely but only receded significantly).

Not only does this theory explain the same geological features which the plate tectonic theory tries to explain, and does it in a way which explains geological mysteries that tectonics has difficulties explaining, but it also appears to throw light on many mysterious aspects of mankind’s ancient past. For example, it is no doubt well-known to readers of this website that many ancient monuments are very precisely aligned with celestial phenomena (such as the rise or transit of important stars or constellations), solar stations (such as the rising or setting of the sun on the equinoxes, solstices, or cross-quarter days), and occasionally with significant points on the lunar cycle, or with the cardinal directions (the Great Pyramid being a notable example of alignment with cardinal directions as well as with celestial phenomena). Many of these ancient monuments are thousands of years old. If the theory of plate tectonics is correct, proposing as it does that continental plates often move an inch a year (sometimes more, sometimes less), how is it possible that any of these alignments are still intact? At an inch a year, the Great Pyramid, Stonehenge, and the megalithic temples on Malta would have drifted hundreds of feet, and yet all of them still display astronomical alignments, solar alignments, cardinal direction alignments, or a combination of the above. The hydroplate theory argues that the plates did slide, but that they did so once, and that they are no longer drifting about the way the tectonic theory says they are. They do continue to shift on occasion (which is one cause of earthquakes, especially in those areas next to the Pacific basin), but they do not drift. The monuments mentioned above, of course, were built after the cataclysmic flood, and hence supporters of the hydroplate theory are not surprised that they are still aligned.

This question of the ongoing alignments of ancient monuments is just one example of the intersection of geological theory and ancient human history, and an example of the importance of examining the two in conjunction with one another, because they are intimately connected. Another example is the explanation of the sedimentary layers found around the globe. Conventional theory holds that these were laid down over hundreds of millions of years, but the hydroplate theory argues that they were laid down during the flood event. In fact, many geological features seem to indicate that these layers were all soft and pliable when force was applied to create buckling or folding of these layers, which is consistent with the hydroplate theory and not with a theory of millions of years (in which case the layers would be brittle and would not exhibit the graceful curves and folds seen in many places on earth). Of course, if the strata were all laid down during the flood event, then the assumption that fossils (including human fossils) found in certain layers must be extremely old may well be completely incorrect. Strangely, even alternative researchers who reject the conventional explanations typically assume that human fossils or artifacts found in strata associated with great age are evidence that modern humans have been around for hundreds of millions of years, instead of considering the possibility that perhaps the strata are younger than the conventional theorists assume.

The hydroplate theory argues that the thickening of the continental plates at the end of the flood (when they ground to a halt) could have altered the rotational alignment of the earth. By far the thickest of the continents is found in the region of the Himalayas, home to the highest mountains on the globe. If this region was formed rapidly during a catastrophic event (as the hydroplate theory argues that it was), it would have acted like a big lead weight slapped onto the side of the spinning earth. The laws of physics would argue that this weight would want to move towards the equator by the principle of centrifugal force (if you spin a weight on a string around your head, it will naturally want to spin straight outwards). The Himalayas would have pulled towards the equator, but the bulge of the earth’s extra mass at the equator (the “spare tire” of mass at the equator, also caused by centrifugal force) would have acted to counterbalance this motion, and a kind of “tug-of-war” would have ensued. It was a tug-of-war which the larger equatorial bulge would have ultimately won, but not without a compromise, and in the process the entire earth would have rotated as much as 35o to 45o, moving the areas that were formerly at the poles to new latitudes, and swinging land that had been in temperate latitudes up to the Arctic and down to the Antarctic. This side-effect of the global flood would explain the anomalous fossils of the far north and far south, and it would also explain the submarine feature at the bottom of the Indian Ocean known as Ninety East Ridge, which points generally towards the Himalayas and which is an important supporting piece of evidence for this aspect of the theory.
==============

Walt Brown provides his entire book describing this theory online, and also available for purchase. The main explanation is presented in Part's I and II of In the Beginning: Compelling Evidence for Creation and the Flood (http://www.creationscience.com/onlinebook/PartI.html)

One of many interesting details - he conjectures that the great mountain ranges forced up by this cataclysmic event, such as the Himalayas, caused the earth's tilt to change, moving the North Pole from somewhere near what's now Mongolia to it's current location. Spinning sphere's in free space will tend to tilt so that their greatest mass is nearer their equator.

===

I would also speculate that the Biblical Christian wrapping that Walt Brown puts around his theory provides it a useful bit of immunity from current suppression of "unscientific" thought, as it makes his hydroplate theory easier to ridicule. As court jesters learned long ago, one can get away with telling more inconvenient truths if one enables easier ridicule of one's self or one's words.

===

Walt's presentation is a hallmark of well done science, in my view, presented by someone who has spent years refining their skills at presenting and teaching technical subjects.

===

A number of details of the earth's current geology, fossil record, composition of meteors striking the earth, and other such matters make much more sense to me now.

Another bit of research, supporting Walt Brown's Hydroplate theory:

Uranium Halos are Proof Noah Flood Laid the Sedimentary Layers

The discoveries in this video reveal that the sedimentary layers that the Atheist scientists in the public schools and colleges are teaching were different ages that occurred over millions of years were laid in the flood described in the Bible when it reveals that all of the coalfield log samples taken from all of these so called age layers had compressed Uranium halos in them, which means that all of the layers had to be freshly laid when the compression event that elongated the halos occurred and the lead uranium ratios in all of the samples were the same.

For those who are not prone to reading, just skimming.

Massive oceans of water hiding 400 miles under Earth’s surface (http://www.techtimes.com/articles/8430/20140614/massive-oceans-of-water-hiding-400-miles-below-earth-s-surface.htm)

It was recently found that below the surface of the earth, we have MASSIVE amounts of water. More than the earth's oceans, by a minimal multiple. To start. That is the least that is now beyond theory and into 'fact'. There may be more. There may be far more. Which is enough to be a 'grease' between the mantle layers, or act in other ways. So, no more an oddball theory.. but based on data that is considered to be factual.


We knew for a while that there was some water below the Earth's surface, but we never knew how much. Scientists theorized that the water levels in the Earth's interior might be comparable to those on the surface, but a recent study now gives rock-hard proof.

The rock is ringwoodite and the proof is its melting capabilities. Ringwoodite is a mineral that can trap water in its molecular structure and is formed under high pressures and temperatures, such as those inside our planet. Specifically, ringwoodite is formed under conditions such as those found in the transition zone of the planet, approximately 255 to 410 miles below the surface. This zone is the boundary between the upper and lower mantle, and is hot and bothered, constantly shifting and producing seismic waves. It turns out that this zone is also a deep reservoir of water.

We also have (again, for the skimmers) a record of an 'ancient flood' tale, from approximately 200-250(?)(a huge number of separate tales) separate indigenous groups of people.

Then the Sumerian tale, the Anunnaki tales. How these 'sky people' failed to tell their 'genetically created slave race', which was overpopulating the planet (hey, they were created to do so-to breed), that this event was about to happen, and we had the flood. Most of the earth avatars (humans - GMO chimps) were erased.


The monuments mentioned above, of course, were built after the cataclysmic flood, and hence supporters of the hydroplate theory are not surprised that they are still aligned.


This is written of, directly, in the Sumerian cuneiform records. A notable part of WHY the US went INTO Iraq, as the Germans and the Iraqi archeologists had dug that and more... much more... out of the sands of Iraq.

Which was WHY the Baghdad museum was completely sacked and pilfered, by a highly efficient organized force, on the very night of the initial bombing. To get that data OUT, and under control. To keep it to themselves, and to erase it before it could become known. Then what was being considered the "world's most important archeological find - in all of known or suspected human history" was erased in the same invasion, and the black ops corps and outfits moving in and creating bases on the dig sites.

No-one even knows about this "most freaking mind bending huge scientific archeological dig/find to ever happen, a human epoch event", anymore. The record of it coming into being, from before the invasion, even that is being silenced.

And so on.

Here's another article on the store of water beneath the earth's crust: Rare Mineral Ringwoodite Included within Diamond Points to ‘Oceans’ beneath Earth (Sci-News.com; Mar 14, 2014) (http://www.sci-news.com/geology/science-ringwoodite-oceans-beneath-earth-01806.html).

A 60 micro-meter tiny spec of ringwoodite was found in 2009 by a team of researchers led by Prof Graham Pearson from the University of Alberta, Canada. The spec of ringwoodite was inside this 3 mm diamond:
http://cdn4.sci-news.com/images/2014/03/image_1806_1-Ringwoodite.jpg
The diamond mineral was originally found in 2008 in Brazil by some miners. It had been brought to the Earth’s surface by a volcanic rock known as kimberlite – the most deeply derived of all volcanic rocks.

Pearson, et al, published their results in this March 2014 letter to Nature.com: Hydrous mantle transition zone indicated by ringwoodite included within diamond (http://www.nature.com/nature/journal/v507/n7491/full/nature13080.html). The abstract for this letter begins:

================



The ultimate origin of water in the Earth’s hydrosphere is in the deep Earth—the mantle. Theory and experiments have shown that although the water storage capacity of olivine-dominated shallow mantle is limited, the Earth’s transition zone, at depths between 410 and 660 kilometres, could be a major repository for water, owing to the ability of the higher-pressure polymorphs of olivine—wadsleyite and ringwoodite—to host enough water to comprise up to around 2.5 per cent of their weight.
================

The above Sci-News.com article includes this graphic of the earth's crust and mantle layers:
http://cdn4.sci-news.com/images/2014/03/image_1806_2-Ringwoodite.jpg

That same article concludes:

================



The sample underwent years of analysis using spectroscopy and X-ray diffraction before it was officially confirmed as ringwoodite.

The discovery confirms about 50 years of theoretical and experimental work by geophysicists, seismologists and other scientists trying to understand the makeup of the Earth’s interior.

Scientists have been deeply divided about the composition of the transition zone and whether it is full of water or desert-dry. Knowing water exists beneath the crust has implications for the study of volcanism and plate tectonics, affecting how rock melts, cools and shifts below the crust.

“One of the reasons the Earth is such a dynamic planet is because of the presence of some water in its interior. Water changes everything about the way a planet works,” Prof Pearson concluded.================

By the way, if Walt Brown's hydroplate theory is correct on the origin of the meteors that strike the earth, then these meteors, and the ringwoodite within them, originally came from earth and were blown out of earth orbit by the massive eruptions that began the great flood.

In which case, the above discovery by Pearson, et al of ringwoodite within a diamond brought to the earth's surface in volcanic rock would not be the first ringwoodite we've found that originated from earth ... just the first ringwoodite we've found that even conventional geologists would agree originated from earth.

Thank you for the video post. I found their research very interesting and as well documented as most other theories.

The theory of evolution is based on very thin evidence. Over time, when isolated, finches do develop different characteristics, but they are still finches.

Although I have never accepted creation and timelines recorded in the Bible as accurate without error, I don't totally discount them either. There may also be actual events as the basis for many stories that are considered to be myths.

I have also parted ways with my early religious roots, but have developed a much deeper spiritual awareness than what was presented to me by religion. That awareness was long and slow in developing.

The Bible does contain some jewels: 1 Kings 19:12 And after the earthquake a fire; but the Lord was not in the fire: and after the fire a still small voice.

very interesting, Walt Browns theory...
he seems to be coming from the 'we got to prove that the bible is right' direction, so there is some bias,

what this theory goes well with is the idea that the moon wasn't always here and has been put into orbit artificially.
placing the moon into orbit may have created the imbalance leading to the catastrophic shift...

Brown definitely has that bias, and when it comes to how he speculates that earth came to have a mile of water, some ten miles below a granite surface, some 5000 years ago, that bias shows. I do not agree with his openly Biblical views of how the earth was created, between 6000 and 5000 years ago on his time scale.

But in the main substance of his work, figuring out what happened from the commencement of the great flood and in the 5000 years since, and relating that to currently available evidence of the earth's geology, he is firmly based in logic, analysis, research with clear references and evidence, and and clear presentation.

I read the bulk of his main work, part's I and II of In the Beginning: Compelling Evidence for Creation and the Flood (http://www.creationscience.com/onlinebook/PartI.html), without noticing a single suggestion of his religion ... and given that I am a bit allergic to Christianity, that says something. He may well have some motive to find science that fits with his understanding of the Bible, but find and present science he did, that fits exactly as well with my heretical beliefs.

As I wrote above, choose your wrapper, Christian Creationist or Scientific Materialism, but once you get past your choice of wrapper, Walt Brown has one damn fine piece of scientific work here.

The Truth Is In There

i only skimmed through this but i have to say that shifting of the earth's axis as cause for a worldwide flood event makes more sense to me than some large underwater reservoir that suddenly erupts. i believe there are also different historical accounts that talk about the sun setting twice or moving backwards.

also, maybe i miss something here but how did the water accumulate there in the first place and do the temperatures in that region fit the theory? i mean, to be water it has to be between 0°C and 100°C, otherwise it's solid or gas and neither of these can cause a flood.

Interresting, but to me it sounds a bit illogic, I think the tilting of the Earth caused the flooding.

From all the stuff I read and watched etc. over the years i get a somewhat different timeline that I think is more logic or at least plausible.

Earth was formed out of a piece of Tiamat after this planet was struck by an Moon-sized Spaceship like the Death-star.
The Terra papers describe a battle between 2 such moon-sized space-ships, one was steered into Tiamat, destroying the planet into the Asteroid belt and the largest chunk became the Earth, the other moonsized spaceship was damaged and abandoned and drifted towards Saturn, and I think Iapetus is that battle-star.
This story I also read in a series of youtubes about the Akkadian tabblets, unfortunetly i cant find these videos anymore, but I had 2 sources telling the same story.

Another vid I think is confirmation is about how Earth is growing.

oJfBSc6e7QQ

The tilting of the Earth was caused by placing the Moon into Orbit around 12,500,000 years ago (Credo Mutwa)
The tilting caused the equator swelling to a new position to where it is now, and the old swelling sank down, causing the sinking of Atlantis and probably other parts as well like Yonaguni etc... The new swelling also caused the Grand Canyon to form.
During this flooding a lot of sediment was layed down espcially in Africa, and such... the old ruins are about 15 meters below the newer ruins in Egypt, and there are other sites where ruins have been buried like Goblekli Tepe.

Around 6000 years ago there was a nuclear devastation after wich the Annunaki left, and 7 yrs after Enki dictated his memories to be written on clay tabletts, much of this has been translated and interpreted to become part of the old testament.
Probably also the Cause of Earth being said is 6000 yrs old.

to be water it has to be between 0°C and 100°C, otherwise it's solid or gas and neither of these can cause a flood.
U forget pressure, the 0°C and 100°C are at a pressure of 1 atm.

At great dept the pressure of the water is so high that ice cant form, Ice when it forms takes more space than liquid water because it forms crystals and floats on water. Also at High pressure water can get hotter than 100°C, like in a high pressure cooking pan.

Is this confirmation of just such a Hydroplate? A tip-of-the-hat for this link to headlines on SteveQuayle.com listed for 2014-11-30.

From Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over (ExtremeTech.com; June 17, 2014) (http://www.extremetech.com/extreme/184564-scientists-discover-an-ocean-400-miles-beneath-our-feet-that-could-fill-our-oceans-three-times-over#):

~~~~~~~~~~~~~~~



After decades of theorizing and searching, scientists are reporting that they’ve finally found a massive reservoir of water in the Earth’s mantle — a reservoir so vast that could fill the Earth’s oceans three times over. This discovery suggests that Earth’s surface water actually came from within, as part of a “whole-Earth water cycle,” rather than 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 interior layers continue to function, the more accurately we can predict the future. Weather, sea levels, climate change — these are all closely linked to the tectonic activity that endlessly churns away beneath our feet.

This new study, authored by a range of geophysicists and scientists from across the US, leverages data from the USArray — an array of hundreds of seismographs located throughout the US that are constantly listening to movements in the Earth’s mantle and core. After listening for a few years, and carrying out lots of complex calculations, the researchers believe that they’ve found a huge reserve of water that’s located in the transition zone between the upper and lower mantle — a region that occupies between 400 and 660 kilometers (250-410 miles) below our feet. [DOI: 10.1126/science.1253358 (http://www.sciencemag.org/content/344/6189/1265) - "Dehydration melting at the top of the lower mantle"]

http://www.extremetech.com/wp-content/uploads/2013/04/Earth-crust-cutaway-english.svg_-640x439.png
As you can imagine, things are a little complex that far down. We’re not talking about some kind of water reserve that can be reached in the same way as an oil well. The deepest a human borehole has ever gone is just 12km (http://www.extremetech.com/extreme/154357-earths-core-is-much-hotter-than-previously-thought-hotter-than-the-surface-of-the-sun) — about half way through the Earth’s crust — and we had to stop because geothermal energy was melting the drill bit. 660 kilometers is a long, long way down, and weird stuff happens down there.

Basically, the new theory is that the Earth’s mantle is full of a mineral called ringwoodite. We know from experiments here on the surface that, under extreme pressure, ringwoodite can trap water. Measurements made by the USArray indicate that as convection pushes ringwoodite deeper into the mantle, the increase in pressure forces the trapped water out (a process known as dehydration melting). That seems to be the extent of the study’s findings. Now they need to try and link together deep-Earth geology with what actually happens on the surface. The Earth is an immensely complex machine that generally moves at a very, very slow pace. It takes years of measurements to get anything even approaching useful data. [Read: Is earthquake prediction finally a reality? (http://www.extremetech.com/extreme/153197-quakefinder-earthquake-prediction-technology)]

Earth’s underground ringwoodite ocean [Image credit: The Guardian (http://www.theguardian.com/science/2014/jun/13/earth-may-have-underground-ocean-three-times-that-on-surface)]
With all that said, there could be massive repercussions if this study’s findings are accurate. Even if the ringwoodite only contains around 2.6% water, the volume of the transition zone means this underground reservoir could contain enough water to re-fill our oceans three times over. I’m not saying that this gives us the perfect excuse to continue our abuse of Earth’s fresh water reserves (http://www.extremetech.com/extreme/170784-recycling-closed-loop-shower-is-cleaner-greener-and-can-save-you-1000-per-year), but it’s definitely something to mull over. This would also seem to discount the prevailing theory that our surface water arrived on Earth via a bunch of icy comets.

Finally, here’s a fun thought that should remind us that Earth’s perfect composition and climate is, if you look very closely, rather miraculous. One of the researchers, talking to New Scientist, said that if the water wasn’t stored underground, “it would be on the surface of the Earth, and mountaintops would be the only land poking out.” Maybe if the formation of Earth had be a little different, or if we were marginally closer to the Sun, or if a random asteroid didn’t land here billions of years ago (http://www.extremetech.com/extreme/147978-finally-confirmed-an-asteroid-wiped-out-the-dinosaurs)… you probably wouldn’t be sitting here surfing the web.

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 Science and said the discovery suggested Earth’s water may have come from within, driven to the surface by geological activity, rather than being deposited by icy comets hitting the forming planet as held by the prevailing theories.

“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,” Jacobsen said.

“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. Scientists have been looking for this missing deep water for decades.”

Jacobsen and his colleagues are the first to provide direct evidence that there may be water in an area of the Earth’s mantle known as the transition zone. They based their findings on a study of a vast underground region extending across most of the interior of the US.

Ringwoodite acts like a sponge due to a crystal structure that makes it attract hydrogen and trap water.

If just 1% of the weight of mantle rock located in the transition zone was water it would be equivalent to nearly three times the amount of water in our oceans, Jacobsen said.

The study used data from the USArray, a network of seismometers across the US that measure the vibrations of earthquakes, combined with Jacobsen’s lab experiments on rocks simulating the high pressures found more than 600km underground.

It produced evidence that melting and movement of rock in the transition zone – hundreds of kilometres down, between the upper and lower mantles – led to a process where water could become fused and trapped in the rock.

The discovery is remarkable because most melting in the mantle was previously thought to occur at a much shallower distance, about 80km below the Earth’s surface.

Jacobsen told the New Scientist that the hidden water might also act as a buffer for the oceans on the surface, explaining why they have stayed the same size for millions of years. "If [the stored water] wasn't there, it would be on the surface of the Earth, and mountaintops would be the only land poking out," he said.

Cycling water through the transition zone

The water cycle involves more than just the water that circulates between the atmosphere, oceans, and surface waters. It extends deep into Earth's interior as the oceanic crust subducts, or slides, under adjoining plates of crust and sinks into the mantle, carrying water with it. Schmandt et al. combined seismological observations beneath North America with geodynamical modeling and high-pressure and -temperature melting experiments. They conclude that the mantle transition zone—410 to 660 km below Earth's surface—acts as a large reservoir of water.

Abstract

The high water storage capacity of minerals in Earth’s mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle. We examined the effects of downwelling from the transition zone into the lower mantle with high-pressure laboratory experiments, numerical modeling, and seismic P-to-S conversions recorded by a dense seismic array in North America. In experiments, the transition of hydrous ringwoodite to perovskite and (Mg,Fe)O produces intergranular melt. Detections of abrupt decreases in seismic velocity where downwelling mantle is inferred are consistent with partial melt below 660 kilometers. These results suggest hydration of a large region of the transition zone and that dehydration melting may act to trap H2O in the transition zone.

For those who are not prone to reading, just skimming.

Massive oceans of water hiding 400 miles under Earth’s surface (http://www.techtimes.com/articles/8430/20140614/massive-oceans-of-water-hiding-400-miles-below-earth-s-surface.htm)

It was recently found that below the surface of the earth, we have MASSIVE amounts of water. More than the earth's oceans, by a minimal multiple. To start. That is the least that is now beyond theory and into 'fact'. There may be more. There may be far more. Which is enough to be a 'grease' between the mantle layers, or act in other ways. So, no more an oddball theory.. but based on data that is considered to be factual.


We knew for a while that there was some water below the Earth's surface, but we never knew how much. Scientists theorized that the water levels in the Earth's interior might be comparable to those on the surface, but a recent study now gives rock-hard proof.

The rock is ringwoodite and the proof is its melting capabilities. Ringwoodite is a mineral that can trap water in its molecular structure and is formed under high pressures and temperatures, such as those inside our planet. Specifically, ringwoodite is formed under conditions such as those found in the transition zone of the planet, approximately 255 to 410 miles below the surface. This zone is the boundary between the upper and lower mantle, and is hot and bothered, constantly shifting and producing seismic waves. It turns out that this zone is also a deep reservoir of water.


Aha - yes - all I've done in my three earlier posts today, just above, is to provide more links to discussions of this same result that you, Carmody, provided us in July of this year, 2014.

Thanks :).

The study by Schmandt and Jacobsen used seismic waves to detect magma generated near the top of the lower mantle at about 700 km depth. Dehydration melting at those conditions, also observed in the study’s high-pressure experiments, suggests the transition zone may be nearly saturated with H2O dissolved in high-pressure rock.

KQED is a radio station in the bay area, and their science editor, Andrew Alden, has a degree in geology and has been writing on subjects such as this for many years. He posted this clear, and so far as I know, accurate explanation of the Science article that my last few posts have been describing.

The following article by Andrew Alden is from the KQED blog at New Evidence of Earth’s Deep Water Cycle Reveals A Virtual Buried Ocean (http://blogs.kqed.org/science/2014/06/12/new-evidence-of-earths-deep-water-cycle-reveals-a-virtual-buried-ocean/):

~~~~~~~~~~~~~~~



Water is part of Earth’s very definition as a planet. Clouds of water fill its atmosphere, oceans cover most of its surface, and groundwater is found everywhere underground. For the last century, geologists have been tracing the influence of water deeper and deeper into Earth’s interior. During the last year, whole oceans worth of water have been found in the mantle, hundreds of kilometers below the crust. And a paper in today’s issue of Science traces water’s influence all the way down to an important boundary inside the Earth, the top of the lower mantle.

The study, by a team of five scientists led by Brandon Schmandt (University of New Mexico) and Steven Jacobsen (Northwestern University), combined high-pressure experiments on minerals with high-precision seismic observations to argue that large amounts of melted rock—magma—exist far deeper than the magma feeding volcanoes on the Earth’s surface. Their research involved the transition zone, the bottom part of the upper mantle between 410 and 660 kilometers deep.

A paper earlier this year in Nature reported that ringwoodite, the most common mineral in the transition zone, can contain more than 1 percent of water inside its crystal structure, a significant amount. Schmandt and Jacobsen’s team did an elegant experiment to show what would happen to ringwoodite as it hits the bottom of its comfort zone at 660 kilometers depth. At that depth ringwoodite breaks down and forms two new minerals, neither of which can hold as much water. They laser-heated tiny spots in a water-bearing ringwoodite sample, forcing it to form the two higher-pressure phases, and showed that the water expelled during this process formed a thin layer of melt around the edge.

Right, electron micrograph of the edge of dot 2 shows perovskite crystals and a rim of melt. From Figure 1 of Schmandt et al., “[url="http://www.sciencemag.org/lookup/doi/10.1126/science.1253358[/url]"]Dehydration melting at the top of the lower mantle,” Science vol. 344, p. 1265-1268.
Next, they analyzed the high-quality data from the great USArray seismic experiment, a 10-year project that has been mapping the mantle beneath the United States with a set of hundreds of seismometers, moving from area to area like a doctor using a stethoscope. The behavior of earthquake waves down at the base of the transition zone matches what would be expected from large areas of melt. More precisely, these would be large areas in which a small fraction of the rock, consisting of the hair-thin spaces between mineral grains, is molten. Just as dry sand behaves very differently when it has a small amount of water between its grains, so too does the rock of the mantle. Wet sand is stiffer than dry sand, but wet mantle is the opposite—softer and more pliable. The slippery layer in the uppermost mantle that allows the tectonic plates to move about—the asthenosphere—that’s wet mantle.

The picture Schmandt and Jacobsen’s team present in their paper is one in which the stirrings in the mantle, caused by plate tectonics, move large volumes of rock into and through the transition zone. As these move down through the 660-km level, most of the water they contain is released and left behind. A similar reaction is already known to take place as rock moves upward through the upper edge of the transition zone, leaving water behind. This new paper puts the lower boundary into the story too, suggesting that the transition zone tends to retain water over geologic time. It may even function like the asthenosphere higher up in the mantle.

The only thing I need to add to this is a disclaimer about water. The lava in volcanoes contains real water, H2O, dissolved in it that comes out in the form of steam. Magma in the uppermost mantle, the stuff that directly feeds volcanoes, has real water in it. But water lower in the mantle, trapped inside ringwoodite, is not water as we know it. It is hydroxyl, or OH as opposed to H2O. Think of it as dehydrated water. The result, in terms of creating melt and enlivening activity in otherwise solid rock, is the same. The exact connections between these two deep water cycles are still to be discovered.
