SDO14089 - Geophysical Survey Report Corfe Mullen to Salisbury WTS

A detailed gradiometry survey was conducted over approximately 36 locations along two proposed new water pipeline routes across Wiltshire and Dorset. The gradiometer data has predominantly been collected in a 50m corridor concentrating on sites of potential archaeological activity. The data collected has identified several areas of increased archaeological potential. Positive and negative anomalies are observed in curvilinear and circular forms which may be indicative of prehistoric settlement activity. Further evidence of infilled cut features such as pits and ditches can be seen across the majority of the site and are of possible archaeological origin, however a natural or modern cause is also possible. Modern activity on the site is evident through the high amplitude resposnse associated with modern field boundaries, services and ferrous materials. Also evident are anomalies associated with modern agricultural activity such as ploughing and areas of amorphous magnetic variation of a probable natural cause.
