Diamond Suggests Presence of Water Deep Within Earth 48

Posted by samzenpus
from the deep-water dept.
sciencehabit writes "A 40 micrometer crystal trapped inside a diamond unearthed by magma in Brazil could help settle a long-standing debate about the amount of water in Earth's mantle. Spectroscopic analysis reveal that the crystal contains hydrogen-oxygen bonds, which suggests it's composed of at least 1.4% water. The place where the diamond was produced--Earth's lower mantle--may not be typical of the entire lower mantle, but if it is then there could be a lot of water down there. This would be important, as changes in the temperature in the mantle could cause it to expel highly pressurized steam, which could lead to volcanic eruptions."

    Hans Keppler, a geologist at the University of Bayreuth in Germany, cautioned against extrapolating the size of the subterranean water find from a single sample of ringwoodite.

    And he also said

    "In some ways it is an ocean in Earth's interior, as visualised by Jules Verne... although not in the form of liquid water," Keppler said in a commentary also published by Nature.

    Ain't nothing swimming around down there.

      "This sample really provides extremely strong confirmation that there are local wet spots deep in the Earth in this area,"

      Did they have to roll it around in flour to find out? Just wondering.

      I find it amazing how much Jules Verne envisioned in 20,000 Leagues Under the Sea. Basically he came up with the idea of a nuclear submarine before the advent of nuclear power. What I also learned even in 1870 when it was published, that very little about Antarctica was known, and the first undisputed landing didn't take place until 1895.

      His writings in Journey To The Center Of The Earth turned out to be much less real, but you still have to admire his imagination.
  • Are there a lot of diamonds from where the water came from ? (:grin:)

    A lot of people still not aware that deep within earth is lots of water and vegetation. Forget what you heared in school about earth inner structure, those are simply provided to misguide you. Deep within every planet is an eco system much better than what we have on the surface of the earth.

    This is really obscure - it might take a couple of months, but I predict that this is at some point going to be noticed by creationists who will then read the summary (not the paper of course, just the summary) and proudly declare that this is where the water from the great flood disappeared to.

      It gets worse; the Guardian's comments are full of people sneering about how we are going to destroy this precious natural water resource now we know it's there. Part of me died inside.

      • Those are just idiots. My threshold for dying inside is when research institutions start claiming that AGW is causing temperature increases in the mantle, and is causing increases in volcano activity as a result, enough that it could put our future in danger.

      The predominant theory among creationists is that the water of the flood is mostly most in the oceans -- The elevations of the continental masses where raised, allowing the water to flow to the oceans. This is kind of the same as the scientific opinion except for the timeframe of months vs. millions of years. Well, that and the scientific opinion that there was no world-wide flood/

    • I don't want to venture in the debate of religion vs science however it is clear that science is never settled and our understanding can change overnight.
      • While religion is never settled and usually takes about a century to change, after which adherents will insist it was like that all alone.

      The study is interestingly-timed, given the 3/28/14 release of http://www.imdb.com/title/tt19... [imdb.com].

      Long past that point. I can remember seeing something on the internet at least a decade ago talking about not only where the water went to, but where it came from to begin with. The idea that there is water trapped deep in the mantel is not new or surprising. It has been known for along time, this is just more and better evidence.

  • I suggest we send a rover to check for signs of life immediately.

  • Pressurized water coming up from above. That's how God flooded the Earth before, and he's ready to do it again! For $25/mo I will reserve a spot to have your lawn mowed after you've been raptured.

      Bad plan, everyone knows I won't care about watering my lawn post-rapture. Not that there is ever going to be a rapture, or is even mentioned in the Bible rapturists claim to follow.

  • I thought underground water being stored in molten rock material was already proved during russia's borehole experiment:

    "To scientists, one of the more fascinating findings to emerge from this well is that no transition from granite to basalt was found at the depth of about 7 km, where the velocity of seismic waves has a discontinuity. Instead the change in the seismic wave velocity is caused by a metamorphic transition in the granite rock. In addition, the rock at that dept

  • Sometime ago, an accountant ran around screaming that oil is created by the earth. Now, here the possibility of heat and pressure with Carbon and water. Makes you wonder.
