Researchers from the United States, Switzerland, England and Saudi Arabia are collaborating on the study of dwindling aquifers worldwide. With the help of NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites, the volume of water stored underground can be estimated through detected changes in earth’s gravity field. Measurements have been taken from wells around the globe over an eight-year period for the study. The Gauntlet report | READ MORE
