Abstract: |
A temporary grid system will be established over the site and marked out using canes. The location of the grid will be set out using an RTK GPS system theoretically accurate to some 0.01m and referenced to OS co-ordinates. Data will be 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 will be 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 identified several magnetic responses that are of clear archaeological interest. These include three enclosures or partial enclosures, which are possibly of Iron Age or Romano-British date. An additional area, comprising much weaker magnetic responses indicative of enclosures and ring ditches, has been classified as being of possible archaeological interest. Numerous former boundaries, both corroborated and conjectural, have been mapped, including the existing parish boundary between Milverton and Halse. Several uncertain responses have also been recorded. |
