The GEM Center

The GEM Center is a research center that provides a multidisciplinary/crosscutting approach to groundwater evaluation and management. The focus of research is the integration of data, acquired across a wide range of spatial and temporal scales, to monitor and model subsurface hydrologic processes.

The defining characteristic of the GEM Center is the use of geophysical data as an essential part of all aspects of groundwater evaluation and management. Central to our approach is the establishment of partnerships that allow the GEM Center to demonstrate state-of-the-science solutions to "real-world" problems.

In this way, we hope to play a key role in encouraging the adoption of new approaches, and new technologies, for addressing the challenging problems we face in the evaluation and management of our groundwater resources.

Mapping Seawater Threat to California Central Coast Aquifers

Stanford News

Researchers from Stanford and the University of Calgary have transformed pulses of electrical current sent 1,000 feet underground into a picture of where seawater has infiltrated freshwater aquifers along the Monterey Bay coastline.

Stanford project maps underground water — aimed at taking the guesswork out of well drilling

The Mecury News

The Stanford University-led project, the first of its type in California, is aimed at taking the guesswork out of well drilling — and guiding restoration of precious groundwater supplies once winter rains start soaking the state.

Stanford takes crack at studying Central Coast aquifer seawater intrusion

Santa Cruz Sentinel

Focusing on a 1,000-foot-deep two-dimensional slice of ground from Aptos down to Monterey, Stanford University researchers are taking a new tact studying saltwater intrusion along the Central Coast.
