A mineral far below Earth's surface may hold the key to how much water is stored in the planet, a Florida State University researcher says.

In a paper published this week in the Proceedings of the National Academy of Sciences [Abstract], FSU Assistant Professor of Geology Mainak Mookherjee reports that water exists far deeper in Earth than scientists previously thought.

Mookherjee and Andreas Hermann from the University of Edinburgh estimate that in the deep Earth -- roughly 400 to 600 kilometers into the mantle -- water is stored and transported through a high-pressure polymorph of the mineral brucite.

Previously, scientists thought brucite was not thermodynamically stable that deep in Earth. "This opens up a Pandora's Box for us," Mookherjee said.

"We didn't think water could be stored by hydrous minerals such as brucite at these depths. But now that we know it's there, we need to figure out how much water could be effectively stored inside it."
