Interesting section to quote. How about this one?<quoted text>
This is one link from a growing number of scientists in various fields that believe there is more water beneath the earth then there is on it.
So I asked him: "If you had to make a rough calculation, right now, and no one's going to hold you to it, how much water do you think we have on earth?" And he said a conservative (albeit blind) guess would be the earth today carries with it 3 global oceans of water, 1/3 on top, where we can swim in it, sail on it, drink it, get rained on by it, and 2/3rds down below where it sits silently with the minerals.
"In the lower, bigger mantle, the calculations get more theoretical, and therefore chancy, but he guesses anywhere from one tenth to 1.8 global oceans."
"*GUESSES* anywhere from one tenth to 1.8 global oceans." 0.1 to 1.8 is quite a spread. But then, this is only a guess, right?
"Then, all the way down, in the earth's core, nobody knows. There's enough capacity to house 60 oceans. Or maybe 100. The core could be very, very rich in hydrogen (a water ingredient) or totally dry. We have no data. Which leaves us in the odd position of not knowing where most of the Earth's water is."
Love the last two sentences. Also note that hydrogen is not water.
While it is an interesting article and certainly some truth to it, it is far too vague to be taken seriously as an accurate estimate of the total amount of water on the planet.
