For the info direct from the horses mouth, as it were, I looked up the research paper instead of relying on the news article. &#13;&#10;> &#13;&#10;> Extract p.1 of the introduction:&#13;&#10;> &#13;&#10;> The lower mantle accounts for 62% of Earth&apos;s volume,&#13;&#10;> so even if lower mantle minerals have low H2O solubility&#13;&#10;> (< 0.1 wt%), the lower mantle may contain more water than&#13;&#10;> the Earth&apos;s oceans. How much water the lower mantle can&#13;&#10;> hold is a subject of some debate, and considerable discussion&#13;&#10;> in this volume. Estimates for the water solubility in silicate&#13;&#10;> perovskite range from a few ppm [Bolfan-Casanova et al.,&#13;&#10;> 2003] up to 0.2...0.4 wt% (i.e., 2000...4000 ppm H2O by&#13;&#10;> weight) [Litasov et al., 2003; Murakami et al., 2002]. The&#13;&#10;> water solubility for magnesiow&#195;&#188;stite (~16% of the lower&#13;&#10;> mantle) is more uncertain, with measurements from zero&#13;&#10;> [Bolfan-Casanova et al., 2002] to 0.2 wt% H2O [Murakami&#13;&#10;> et al., 2002]. For lower mantle solubilities of 0.05 to 0.2&#13;&#10;> wt%, the lower mantle may hold 1 to 5 times the water in&#13;&#10;> the Earth&apos;s oceans.&#13;&#10;> &#13;&#10;> &#13;&#10;> The article is a good read at any rate, and might be interesting to branch out into another world of science other than biology for a bit.&#13;&#10;> &#13;&#10;David&apos;s more the biologist here as the retired Doctor. I&apos;m the young computer science whippersnapper. -http://en.wikipedia.org/wiki/Mantle_%28geology%29-I&apos;ve now seen volume estimates between 49 and 80% for the Earth&apos;s mantle. Not that Wikipedia should ever be seen as an ultimate source... -&#13;&#10;> Hope you enjoy.

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
