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 numerous magnetic responses that have been interpreted as being of archaeological interest. The results include evidence of enclosed settlement activity comprising enclosures, pits, ditches and ring-ditches. Some of the anomalies correspond with cropmarks that are noted in the HER (MNN129298 and MNN6851) though much more detailed has been added. Ridge and furrow cultivation has also been recorded in Areas 3 and 4. Numerous responses of uncertain origin have been marked in the survey, while archaeological origins cannot be ruled out, they are probably due to natural and agricultural processes. A former field boundary and a few land drains have also been plotted in the data. Two natural amorphous bands of increased response have been detected across Areas 1 and 3 and a service pipe is visible in Areas 2 and 3.
