Geophysics
Used in advance of intrusive techniques, geophysical survey is a valuable tool that can establish the nature and extent of buried archaeology faster and more economically than trial trenching.
Based on identifying and assessing geophysical anomalies in the soil, the production of a broad picture of buried features across a site can help to ascertain the state of archaeological preservation; targeting and potentially minimising further investigations.
L – P’s consultants have a wealth of experience in the UK and Europe from both commercial and research projects. Data collection and report production is in line with English Heritage and IfA guidelines, and strict quality control is undertaken both on site and before processing. Data is georeferenced to results from previous investigations and other surveys, and our reports feature georeferenced images alongside full interpretation of the data with archaeological contextualisation.
Effective geophysical survey depends on the nature of the site, especially its geology. L – P’s consultants always use the methods and equipment that will produce the best results possible including: Magnetometry (differences in the earth’s magnetism across the soil of the site, can show features such as foundation trenches, pits, ditches and burnt materials) and Resistivity (variations in the structural and chemical make-up of the soil or materials buried in the soil, show as changes in resistance to an electrical current. Using Multiplexing hardware this method can reveal archaeological deposits at different depths, even under normally masking anomalies).
Geophysics can be combined with other non-intrusive survey techniques for early assessment of a site, or be included in a comprehensive historic landscape model.
