Geophysical and Geoelectrical Methods

Geophysical and geoelectrical methods use physical signals—electrical currents, electromagnetic waves, and seismic vibrations—to reconstruct what lies beneath Earth's surface without digging into it. By measuring how rocks, fluids, and sediments resist or transmit these signals, researchers can locate groundwater aquifers, map fault structures, monitor contaminant plumes, and probe the seafloor, all from surface or borehole observations. A central challenge is the inversion problem: translating indirect measurements into reliable subsurface images requires mathematical techniques that must balance resolution against the inherent ambiguity in the data. Active research directions include improving the accuracy of spectral induced polarization for distinguishing fluid types and lithology, and developing better ways to integrate seismic, electromagnetic, and resistivity datasets into unified subsurface models.
