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 not recorded any magnetic responses that could be interpreted as being of archaeological interest, except for ridge and furrow cultivation which is visible in the east of the site. Numerous uncertain anomalies have been detected which are likely to be products of underlying geological variations, agricultural processes or buried ferrous debris. The alignments of corroborated / conjectural former field boundaries and a path. have been marked along with a service pipe. Zones of magnetic disturbance have been recorded in the survey which are probably due to spreads of modern debris.
