Geophysical survey is a technique used for detecting and mapping sub-surface archaeology. It is often used as a prospecting tool in advance of development, but can also be used to further characterize a site of known archaeological interest.
This technique is often used in conjunction with evaluation trenching.
Three different types of geophysical survey are commonly used in archaeology:
magnetometry, resistivity and ground penetrating radar (GPR).
Acer Archaeology specialises in geophysical survey and offers three types of in-house geophysical survey and analysis:
- magnetometry;
- resistivity, and
- ground penetrating radar.
