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.
