Using Geophysical Survey Results During Active Commercial Site Investigations

Geophysical surveys are an essential tool in assessing the degree of anthropogenic activity and guides the invasive archaeological investigation strategy. However, variability within deposit composition directly influences the recorded geophysical anomalies; as a result an absence of evidence within the geophysical survey results can lead to alternative interpretations. Interpreting the data in a way which focuses on archaeological form aids the onsite investigation, whilst highlighting areas of uncertainty can safeguard overlooking features without adequate physical property contrast.
Here we review how field archaeologists use geophysical survey results during an active site investigation and show how geophysical interpretations assist and evolve as archaeological features are uncovered. Using the trial trenching at Wixams Park, Bedfordshire and open area investigation at Airfield Farm, Leicestershire as case studies, we analyse how the geophysical surveys influenced these archaeological investigations and suggest approaches which would enhance future investigations.
