This geophysical survey was completed using a Bartington Grad601-2 and Sensys FMG650/3 system. Readings were recorded at a resolution of 0.01 nT and data collected with a traverse interval of 1 m and a sample interval of between 0.16 - 0.25 m. Data was collected by traversing the survey area in 4 increments using a hand-pushed and quadbike-towed non-magnetic cart system to achieve the best possible results. Real Time Kinematic (RTK) differential GPS equipment (Carlson BRX7 GNSS Smart Antenna) was used to accurately determine the position of the survey equipment and survey monitor data. The data processing was undertaken using TerraSurveyor64 software and consisted of a 'DeStripe' process. This process determines the average of the datapoints in each track, and subtracts that value from all the datapoints along each survey track. The survey produced good data throughout and confirmed the presence of a number of anomalies of a likely archaeological and possible archaeological origin. The majority of these anomalies are concentrated in two areas covering the west of Field 4 and north of Field 2, where a large concentration of largely interconnected linear and rectilinear anomalies denotes the presence of a series of ditches, enclosures and possible pits which formed a small settlement characteristic of the Romano-British period. This settlement may have had at least two phases of construction and the presence of a small number of characteristic circular features within the dataset hints at a potential phase of Iron Age or earlier Prehistoric phase preceding its construction, although this is tentative. The settlement had almost certainly been entirely abandoned by the medieval period, as evidenced by the presence of ridge and furrow ploughing within its centre. In addition to earlier archaeological activity, later, medieval, or post-medieval activity is also identified with several probable earlier former boundaries not recorded on historic OS maps of the area identified denoting a probable strip field system with evidence of ridge and furrow cultivation (9, 10, 12). A further former boundary that is recorded on historic OS maps from the 19th Century is also noted in the northeast of Field 4 (11).
