Abstract: |
A temporary grid system was 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. At the end of every data collection a zone of data was recollected as a control. The magnetometer survey has not recorded any magnetic responses that could be interpreted as being of definite archaeological interest. However, strong amorphous ferrous anomalies in Area 6 have an uncertain origin, and could be due to spreads of modern debris, perhaps be related to brick manufacture (based on place-name evidence) or might indicate mining activity. A negative response and several pit-like anomalies have been detected in the survey and have also been assigned to the category of uncertain. The linear anomaly is likely to mark the location of a land drain while the ostensibly pit-like responses are probably due to deeply buried ferrous debris. A former field boundary, land drains plus ridge and furrow ploughing are visible in the dataset. A modern track has also been detected. |
