Magnetometer survey reveals anomalies in land boundaries and features prior to planting trees, indicating potential historical significance.
The detailed magnetic survey was carried out using a SENSYS MAGNETO MX V3 6 channel cart-based system over 4ha prior to a tree planting scheme. The instrument has 6 fluxgate gradiometers (FGM650) spaced 0.5m apart with readings recorded at 20Hz which equates to a survey resolution of 0.5m by c.0.15m Several anomalies associated with formerly mapped field boundaries and land drainage were recorded along with magnetic debris associated with modern infill along one of the boundaries. A fragmented linear ditch-like feature was located just to the north of, and parallel with, one of the former boundaries, but unlike the former boundary ditch the linear anomaly does not have any surface expression.
