Data was collected using a cart carrying four paired Bartington magnetic sensors. Four sensors mounted 1m horizontally apart and very accurately aligned to nullify the effects of the earth's magnetic field. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. Each data point is geographically referenced using an on-board Trimble RTK survey grade GPS system. Readings were taken at 0.125m centres along traverses 1.0m apart. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. The magnetometer survey has recorded magnetic responses that have been tentatively interpreted as being of possible archaeological interest. In Areas 2, 6 and 8 zones of increased response, trends and discrete anomalies have been detected; they could mark the location of enclosures, ditches and pits. However, they are magnetically weak which casts doubt over the interpretation. On balance, archaeological origins cannot be entirely ruled out for the responses, hence their categorisation. Numerous responses of uncertain origin have also been marked across the survey which are probably due to relatively modern landscaping / tree removal, natural variations or agricultural processes. Former field boundaries, ploughing and service pipes have all been plotted in the survey. Natural bands have been detected in Areas 2, 5 and 8.
