Satellites Measure Bulging Earth To Map Water Resources

Summary:
Just as a sponge expands when absorbing water, so too does the Earth bulge slightly where aquifers, underground areas of permeable materials, absorb unusually large amounts of water from stream runoff or heavy rains. Scientists using satellite data have been able to measure these bulges on the land surface and believe they can use the technique to study the location and size of aquifers in remote regions.
