Scientists report a vast, bound water reservoir about 700 km below the surface, stored in the mineral ringwoodite in the mantle's transition zone. Using seismic data from roughly 2,000 stations and 500 earthquakes, they estimate this deep ocean could contain about three times as much water as all surface oceans, suggesting Earth's water partly originates from within and that the deep cycle helps keep surface oceans stable over geological time.
Scientists have discovered a massive reservoir of water hidden beneath the Earth's crust, three times larger than all the oceans on the surface. This water is contained within a blue rock called ringwoodite in the Earth's mantle, 400 miles underground. The discovery was made by measuring seismic waves generated by earthquakes, which revealed the presence of water-containing ringwoodite. This finding could help explain the origin of Earth's water and suggests a whole-Earth water cycle. Further research is needed to determine if this water reservoir wraps around the entire planet.
