Geophysical techniques

We have prepared a series of technical summary sheets that are designed to provide a simple overview of geophysical techniques commonly used in site investigations. More detailed explanations and case study examples are provided in An Introduction to Applied and Environmental Geophysics.

Our technical summary sheets are in pdf format. All pdfs are under 700 kB.

  1. Ground Penetrating Radar (GPR)
  2. Electrical resistivity sounding and tomography
  3. Electro-Magnetic ground conductivity mapping
  4. EM31 Electro-Magnetic ground conductivity mapping
  5. GEM-2 Electro-Magnetic ground conductivity mapping
  6. Transient Electro-Magnetic (TEM) sounding
  7. EM61 Electro-Magnetic metal detection
  8. Microgravity
  9. Magnetic surveys
  10. Seismic refraction surveys
  11. Terrestrial seismic reflection profiling
  12. Continuous Surface Wave (CSW) analysis
  13. Multi-channel Analysis of Surface Waves (MASW)
  14. High resolution over-water seismic profiling
  15. Single-channel seismic interpretation
  16. Side Scan Sonar (SSS) surveying
  17. Induced Polarisation (IP)
  18. Spectral Induced Polarisation (SIP)
  19. Ground-based magnetic prospecting for iron ore
  20. Airborne Time-Domain Electro-Magnetic (TEM/TDEM) surveying
