What is a Geophysical Survey?
Geophysical survey offers a rapid non-intrusive but not wholly reliable method of detecting potential sub-surface archaeology. Techniques include magnetometry, resistivity, magnetic susceptibility and ground penetrating radar, each having a particular strength dependent on the underlying geology, soil conditions and feature type.
What Happens Next?
Geophysical survey is used to identify areas of archaeological interest that can then be examined in more detail by means of test-trenching.
