Study: Vast Underground Ocean Discovered Near Earth's Core

Scientists have discovered vast water reserves near Earth’s mantle, a finding that could reshape our understanding of where Earth’s water came from.

According to a new study by a group of U.S. geophysicists, a reservoir of water three times the volume of all of Earth’s oceans has been discovered inside a layer of blue rock 440 miles deep

Geophysicist Steve Jacobsen of Northwestern University, who coauthored the study, says it’s evidence the planet’s water bubbled up from somewhere underground.

The water is thought to be trapped in a layer of ringwoodite, a rock with a crystalline structure that acts like a sponge, to attract and trap the hydrogen and oxygen atoms that comprise water Read more...
