What is the 6th ocean?

Earth has a sixth ocean, a new study suggests, but not where you can see. It's hundreds of kilometres below the surface. The international study published in Nature Geoscience says this vast reservoir of water is located in the so-called transition zone between the upper and lower mantle at a depth of 410 to 660 kms.
