Abstract: |
The cart-based gradiometer system used a Leica Captivate RTK GNSS instrument, which receives corrections from a network of reference stations operated by the Ordnance Survey (OS) and Leica Geosystems. Such instruments allow positions to be determined with a precision of 0.02 m in real-time and therefore exceeds European Archaeologiae Consilium recommendations (Schmidt et al. 2015). The detailed gradiometer survey was undertaken using eight SenSys FGM650/3 gradiometers spaced at 0.5 m intervals and mounted on a non-magnetic cart. Data were collected with an effective sensitivity of 0.03 nT at a rate of 10 Hz, producing intervals of 0.15 m along transects spaced 4 m apart. Data from the survey were subjected to minimal correction processes. These comprise a ‘Destripe’ function (±5 nT thresholds), applied to correct for any variation between the sensors, and an interpolation used to grid the data and discard overlaps where transects have been collected too close together. The detailed gradiometer survey has been successful in detecting anomalies of archaeological origin. In the north-east of the site, an enclosure of Romano-British origin with internal divisions has been identified. Penannular anomalies have also been recorded within the enclosure, thought to pertain to prehistoric ring ditches. Indicative of multi-phased settlement activity. Across the remainder of the survey, several additional anomalies have been identified as archaeological in origin. Further ditch-like features have been identified, likely former field divisions associated with archaeological activity in the area. Those near the enclosure are likely associated and may represent protective boundary ditches. Multiple linear and curvilinear anomalies have been highlighted as possible archaeology across the site. In the north-east of LP_3, a series of weakly positive anomalies have been identified, forming a rectilinear shape. This assortment may combine to form an additional enclosure of unknown age. It may also be possible that these anomalies are geological in origin. Additional possibly archaeological anomalies have also been interpreted in the form of possible ring ditches and former field boundaries not recorded on first edition OS mapping. Several isolated instances of increased magnetic responses have been identified, resulting from pylons present on site. Additional disturbances located along the periphery of certain fields are likely the result of ferrous material present in current field boundaries. Additionally, former field boundaries, geological and ferrous debris, ridge and furrow, drainage and modern ploughing have also been identified. |
