Geophysical Survey at Station Road, Tadcaster, North Yorkshire LS24 9JR, United Kingdom

All survey work was completed to appropriate standards, as outlined by existing guidelines (CIfA 2020a; Schmidt et al. 2015). The gradiometer survey was completed using Bartington Grad601-2 gradiometer systems with a data logger. Readings were recorded at a resolution of 0.01nT and data collected with a traverse interval of 1m and a sample interval of at least 0.25m. The survey data was collected on site by traversing across the surface in increments utilising a cart system to achieve the best possible results. Real Time Kinematic (RTK) differential GPS equipment was used to accurately determine the position of the survey equipment and monitor data. Sensors were left to acclimatise outdoors for c.30 minutes prior to balancing at the start of each day's survey. The processing was undertaken using TerraSurveyor64 software and consisted of standard processing procedures. Illustrations were created using QGIS software. Interpretation of identified anomalies was achieved through analysis of anomaly patterning and increases in magnetic response and was aided by examining the available supporting information. The interpretations follow Ecus colour coding and categorisations of anomalies and attempt, where possible, to suggest the nature of the buried feature. The survey results have revealed archaeological features at the Site as well as historical and modern cultivation features. A large linear anomaly extends from the northeast boundary of the Site and continues via a slight kink to the southern boundary on Station Road. This has been tentatively interpreted as a former, unrecorded field boundary. Another ditch-like anomaly, potentially forming part of an enclosure, extends from the east side of this feature. A further linear anomaly is visible in the eastern area of the Site on a broadly northeast to southwest alignment. This also been interpreted as a former, unrecorded field boundary, though this indicates a different period of occupation. The survey revealed several circular anomalies across the Site, which are pit-like in shape, although their date of origin is uncertain. Several irregular anomalies are also present to the southwest of the Site, but an archaeological origin cannot be determined. Linear anomalies are visible throughout the Site on a broadly east to west alignment. These have been identified as modern agricultural trends. Ferrous 'spikes' are present in the geophysics data throughout the Site, which are most likely due to sporadic agricultural waste and are probably modern in origin. Larger ferrous disturbances are localised to field boundaries and within the eastern part of the Site. These anomalies probably result from metallic fencing and waste, respectively.
