Look out! Water below? "REALLY" below?

 According to the standard tale, Earth's water was imported. The region around the sun where the planet formed was too hot for volatile compounds like water to condense. So the nascent Earth started out dry, getting wet only after water-rich bodies from the distant solar system crashed into the planet, delivering water to the surface. Most of these were likely not comets but rather asteroids called carbonaceous chondrites, which can be up to 20 percent water by weight, storing it in a form of hydrogen like ringwoodite.

But if there's a huge stockpile of water in the transition zone, this story of water's origin would have to change. If the transition zone could store 1 percent of its weight in water — a moderate estimate, Jacobsen said — it would contain twice the world's oceans. The lower mantle is much drier but also voluminous. It could amount to all the world's oceans (again). There's water in the crust, too. For subduction to incorporate that much water from the surface at the current rate, it would take much longer than the age of the planet, Jacobsen said.

If that's the case, at least some of Earth's interior water must have always been here. Despite the heat in the early solar system, water molecules could have stuck to the dust particles that coalesced to form Earth, according to some theories.

The debate will last a long time as it is tough to arrive at the estimated guess.

One thing we do know. There IS water in the transition zone of Earth (zone between the upper and lower mantle). The upper mantle is appr. 7% of our planet's total mass (compared to the crust being 1% - the crust...i.e., all we "see" land and oceans). So,...

Estimates on the lowest range are 1/2 the water of all our oceans. The highest range is 2 to 3X the water of all our oceans! That's...a LOT of water! (There cannot be more than 3X the water of our oceans)

From the article,...

 Yet the total amount of water in the mantle is a highly uncertain figure. At the low end, the mantle might hold only half as much water as in the world's oceans, according to Schmandt and others.

On the high end, the mantle could hold two or three times the amount of water in the oceans. If there were much more than that, the additional heat of the younger Earth would have made the mantle too watery and runny to fracture the continental plates, and today's plate tectonics may never have gotten started. "If you have a bunch of water in the surface, it's great," said Jun Korenaga, a geophysicist at Yale University. "If you have a bunch of water in the mantle, it's not great."

So what you are saying is "Water water everywhere but not a drop to drink"

I read that article yesterday, found it interesting.

I have read (many years ago) that before the biblical great flood there was a water shield around the Earth. Humans during that time may have lived as long as 50,000 years. After the flood the water shield was gone and human life dropped down to the fifties due to the increased radiation.

50,000? Interesting. Bible records ages in the 900's pre-flood. Some debate whether it meant clans or individuals or just figurative speech. Reading it at face value, it seems to be says individuals lived long lifespans then after the flood (protective shield gone) - ages declined to present day levels (varies a little throughout the ages). It was gradual but still fast. The first few generations still lived long 200 years, etc. Soon it was down to under 100.

Interesting article regardless. Strong evidences but still heated debates going on. If there is, in fact, a huge amount of water between the upper and lower mantles (transition zone) - then the "water from asteroids" theory, once thought full proof, is discredited. That's a big deal (back to the theorizing drawing board).

Genesis 8:1-2

Then God remembered Noah, and every living thing, and all the animals that were with him in the ark. And God made a wind to pass over the earth, and the waters subsided. 2 The fountains of the deep and the windows of heaven were also stopped, and the rain from heaven was restrained.

^^^ Fountains of the deep? NIV describes them as "springs of the deep"

Does the bible tell us waters came from the transition zone and the sky?

Critics say 15 cubits of water covering the earth and needing 150 days to recede is impossible. Cannot have that much water coming from our sky (atmosphere).... What they overlooked was there was another source of water the bible described. From deep below!

^^^ A major clue of information coming from one part of one verse.

Such are the jewels of scripture...
