Geophysical Survey at Site at Welland, Malvern

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. Discrete linear anomalies, trends and apparent pit-like responses have been plotted across the survey which have been assigned to the category of uncertain. Archaeological origins for some of these anomalies cannot be entirely discounted due to the proximity of known archaeological features. However, they may have also been caused by natural variations, modern processes or deeply buried ferrous debris.
