Ground-based transient electromagnetic data and resistivity models at selected sites of the California Central Coast and San Joaquin Valley 2019
Ground-based transient electromagnetic (TEM) data were acquired by the U.S. Geological Survey (USGS) at 16 locations of California’s southwestern San Joaquin Valley and Central Coast regions to define the electrical resistivity structure of hydrogeologic materials. Data were acquired using the ABEM WalkTEM system (Guideline Geo Ab, Sundbyberg, Sweden). TEM data were processed and numerically inverted to derive the one-dimensional resistivity structure at each site using SPIA (Aarhus Geosoftware, Aarhus, Denmark). The resulting models reveal vertical variations in electrical resistivity associated with geologic properties and groundwater salinity.
This release includes raw and processed TEM data and a resistivity model for each data location.
