The survey was undertaken using four Bartington Grad601 sensors mounted at 1m intervals (1m traverse interval) onto a rigid carrying frame. The system was programmed to take readings at a frequency of 10Hz (allowing for a 10-15cm sample interval) on roaming traverses (swaths) 4m apart. These readings were stored on an external weatherproof laptop and later downloaded for processing and interpretation. The system was linked to a Trimble R8s Real Time Kinetic (RTK) differential Global Positioning System (dGPS) outputting in NMEA mode to ensure a high positional accuracy for each data point. MLGrad601 and MultiGrad601 (Geomar Software Inc.) software was used to collect and export the data. Terrasurveyor V3.0.37.0 (DWConsulting) software was used to process and present the data. The geophysical survey has identified anomalies across all parts of the Proposed Development Area (PDA). However, most of these anomalies are due to recent agricultural activity including boundary removal, ploughing and drainage and are of no archaeological potential or interest. One possible enclosure has been recorded in the easternmost field and four discrete anomalies of uncertain origin are also recorded. An archaeological origin for any of these anomalies cannot be dismissed but in all five instances a non-archaeological origin is perhaps more appropriate. Overall, the archaeological potential of the PDA is assessed as low.
