Spotlight Geophysical Services
Advanced Subsurface Solutions

Spotlight Geophysical Services provides innovative, non-intrusive geophysical solutions for geotechnical and environmental challenges. We specialize in site-wide subsurface imaging to support karst (sinkhole) investigations, contaminant mapping, landfill studies, land development, abandoned mine investigations and more.

 

Established in 2009, we have worked on projects across the United States, Caribbean, and Latin America. Our expert team ensures clear, actionable results to guide construction, remediation, and exploration efforts.

Our Services

Geophysical Services

Using advanced, non-intrusive geophysical techniques, Spotlight helps clients understand what lies beneath the surface. Our services support safer, more efficient decision-making for geotechnical, environmental, and land development projects.

Microgravity

A gravity survey measures changes in the Earth’s gravity due to subsurface density variations. Microgravity is a term used to indicate a precision gravity survey in which near surface features are of interest.

Marine Seismic Refraction

Marine seismic refraction is a method to determine the seismic P-wave velocity structure of the subsurface.

Electrical Resistivity Imaging

Electrical resistivity imaging (ERI) provides a means of obtaining a two-

dimensional (2D) cross-section of electrical resistivity.

MASW

Multi-channel Analysis of Surface Waves (MASW) is a

seismic method that uses the dispersive

characteristics of surface waves to determine the

variation of shear-wave (S-wave) velocity with depth.

Seismic
Refraction

Seismic refraction is a geophysical method used to determine the seismic compression-wave (P-wave) velocity structure of the subsurface.

Magnetic and EM Methods

Electromagnetic (EM) measurements respond to metals

(both ferrous and non-ferrous), inorganic contaminants,

and variations in electrical conductivity.

Ground Penetrating Radar

Ground penetrating radar (GPR) uses high frequency electromagnetic energy to acquire subsurface information. Energy is radiated downward into the ground from a transmitter and is reflected back to a receiving antenna. 

Testimonials

"Your geophysics work and the anomalies you detected for the locks and approach channel for the Canal Expansion have been confirmed with very high precision during the excavation."
