Stanford Earth’s Rosemary Knight recently spearheaded a project to map underground freshwater resources and forecast the intrusion of saltwater into aquifers beneath the California coastal town of Marina using SkyTEM data. Stanford Earth’s Rosemary Knight recently spearheaded a project to map underground freshwater resources and forecast the intrusion of saltwater into aquifers beneath the California coastal town of Marina. The project, a collaboration between Stanford, the Marina Coastal Water District, and Aqua Geo Frameworks, involved a low-flying helicopter towing a giant, instrument-laden fiberglass hoop that generated ground-probing magnetic fields that penetrated 1,000 feet beneath the surface. The SkyTEM system.

The video, "Ensuring freshwater sustainability: Mapping groundwater from the air", produced by Stanford Earth outlines the results, and can be seen here.
