Geophysical Survey at Clouds Hill Farm Leatherhead Road Oxshott

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 definite archaeological interest, except for ridge and furrow cultivation. Numerous uncertain responses have been detected in the survey which are probably due to a combination of natural variations, agricultural processes or buried debris. A former corroborated field boundary and conjectural boundary have been identified along with a several land drains. The route of a service pipe is also visible. Zones of magnetic disturbance have been recorded in the magnetic data which are due to spreads of modern debris.
