The survey was undertaken using four Bartington Grad601 sensors mounted at 1m intervals (1m traverse interval) onto a rigid frame. The system was programmed to take readings at a frequency of 10Hz (allowing for a 10-15cm sample interval) on roaming traverses (swaths) 4m apart. These readings were stored on an external weatherproof laptop and later downloaded for processing and interpretation. The system was linked to a Trimble R8s Real Time Kinetic (RTK) differential Global Positioning System (dGPS) outputting in NMEA mode to ensure a high positional accuracy for each data point. MLGrad601 and MultiGrad601 (Geomar Software Inc.) software was used to collect and export the data. Terrasurveyor V3.0.37.0 (DWConsulting) software was used to process and present the data. Headland Archaeology (UK) Ltd was commissioned by RSK ADAS Limited (the Client), to undertake a geophysical (magnetometer) survey, covering approximately 32 hectares, survey north-west of Park Farm, Loudham, near Woodbridge, Suffolk where a solar farm is being proposed. This geophysical survey report will accompany a Desk-based Assessment (RSK ADAS 2021), with both documents being submitted as part of a planning application for the proposed Park Farm Solar Photovoltaic (PV) array and associated infrastructure development. The results will also inform future archaeological strategy, if required. The survey has identified anomalies consistent with modern activity and agricultural usage of the PDA over the past 150 years as indicated on historic mapping. Anomalies indicative of former boundaries and modern cultivation have been recorded throughout the proposed development area (PDA). Five possible former extraction pits have been recorded throughout the site as well as two discrete areas of burning. An enclosure of unknown date has been recorded in the south of the PDA, along with several linear ditch-type anomalies. Additional possible settlement activity has been recorded parallel to Loudham Hall Road in the south of the PDA, where discrete and linear anomalies may indicate archaeological activity such as croft and toft medieval settlement. Based on the geophysical survey results the archaeological potential of the PDA is assessed as low except for F5 where the potential is moderate to high.
