Pilot tests of an aquifer thermal energy storage (ATES) system are underway by Mitsubishi Heavy Industries Thermal Systems and Osaka Metropolitan University in Osaka, Japan. The system is intended to ...

This reservoir of water could be part of a much larger and more complex whole-Earth water cycle that scientists have only begun to understand. The implications of this discovery extend beyond Earth.

Now, after combining this seismic data with models used on Earth to map underground oil fields and aquifers, the researchers determined that igneous rocks (cooled magma) are drenched in liquid water ...

Many of America’s critical sources of underground water are in a state of rapid and accelerating decline, a new study has found. More than half of the aquifers in the United States (53 percent ...

They found evidence of what appears to be a large underground reservoir of water, enough to cover the entire planet in about a mile of ocean. But it’s inaccessible, being located between 7 to 13 ...
