EDO8276 - Charminster (Phase 5); geophysical survey 2025

‘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 a few magnetic responses that could be interpreted as being of possible archaeological interest, namely trends in the north-west of Area 1 mark the presence of ditches. Numerous responses of uncertain origins have also been marked. They are likely to be due to a combination of underlying geological and agricultural processes or buried ferrous debris. Sinuous natural anomalies have also been detected.’
