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. Hand Held: Data will be collected using a Bartington Grad 601-2. The instrument consists of two paired sensors (see below) and readings are logged at 0.25m centres along traverses 1.0m apart across 30m grids. The collection of data at 0.25m centres provides an appropriate methodology balancing cost and time with resolution as per Historic England guidelines. Two 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. A magnetometer survey of 2 hectares of land on the northern outskirts of Great Comberton was carried to investigate the archaeological potential at the site in connection with the Planning Application No: 21/02258/FUL - the excavation of three ponds, a flood retention area and a ditch meander. The results identified a large (60m x 45m) double ditched enclosure with a small, subdivided area, a possible round house and pit-like features. In addition, there may be other ditches. The remains are thought to be associated with known archaeological features recorded south of the survey area. Other responses recorded in the magnetic data include a few uncertain anomalies, geological effects and a small pipeline. The archaeological features are concentrated in the southern quarter of the site away from the location of the Application Areas. |
