Original Note:
This is a 10-year old study of minerals in the mantle converting from ringwoodite to perovskite, releasing a small amount of water 440-660 km below the surface. If 1% of the transition zone contains water, three oceans’ worth of water would be just slightly muddy subsoil. https://news.northwestern.edu/stories/2014/06/new-evidence-for-oceans-of-water-deep-in-the-earth/
