Scientists scanning the deep interior of Earth have found evidence of a vast water reservoir beneath eastern Asia that has at least the volume of the Arctic Ocean.
The discovery marks the first time such a large body of water has found in the planet's deep mantle.
The finding, made by Michael Wysession, a seismologist at Washington University in St. Louis, and his former graduate student Jesse Lawrence, now at the University of California, San Diego, will be detailed in a forthcoming monograph to be published by the American Geophysical Union.
The pair analyzed more than 600,000 seismograms - records of waves generated by earthquakes traveling through the Earth - collected from instruments scattered around the planet.
