The water has been found between the transition zone of the Earth's upper and lower mantle. The research team analyzed a rate diamond formed 660 meters below the Earth's surface using techniques including Raman spectroscopy and FTIR spectrometry.
The study confirmed that ocean water accompanies subducting slabs and thus enters the transition zone. This means that our planet's water cycle includes the Earth's interior.
