Earth May Be Hoarding a Secret Water Stash 1,800 Miles Beneath Our Feet
Yet for all its importance, scientists still do not have a complete picture of where Earth’s water came from in the first place. Now, a new study suggests that the planet’s mantle could be hiding an ancient water reservoir, potentially preserving some of the water that dates back to Earth’s formation billions of years. A team of scientists identified two previously unknown iron compounds capable of storing water under the extreme pressures and temperatures found deep inside Earth.

Opening excerpt (first ~120 words) tap to expand
Water is fundamental to life on Earth. Yet for all its importance, scientists still do not have a complete picture of where Earth’s water came from in the first place. Now, a new study suggests that the planet’s mantle could be hiding an ancient water reservoir, potentially preserving some of the water that dates back to Earth’s formation billions of years. A team of scientists identified two previously unknown iron compounds capable of storing water under the extreme pressures and temperatures found deep inside Earth. The findings, published in Nature Geoscience, offer new clues to our understanding of Earth’s water cycle and interior structure.
