Geophysicists have long theorized that the mantle transition zone, wedged between the upper and lower mantle at depths of 410 to 660 kilometers, could be a secret vault for Earth’s lost water.

According to current scientific theories, the anomalous material in the lower mantle, about 600 miles (1,000km) beneath the water, 'should not be found' there.
