Geophysical survey using Sensys MXPDA towed cart magnetometer. Data will be collected via zig zag traverses and points will be georeferenced via Carlson BRx7 GPS. A gradiometer survey was completed across c.1000.23 ha. The gradiometer survey has successfully located areas of archaeological activity across the wide landscape and over various ground conditions. The clarity of the geophysical results is relatively good, as the local geology is broadly present and, in some places, could affect the interpretation. The survey area is divided into the four major parcels A, B, C and D which are characterised by a moderately quiet magnetic background with strong geological impact in form of alluvial forms characteristic for Fenlands. Anomalies of historical and modern origin were detected across all four sections. Magnetic interference is also visible around the site perimeters, as well as cutting through the survey area and is related to modern infrastructure such as pipes, fences, and pylons. Multiple anomalies of probable and possible archaeological origin have been detected across all of four sections. These represent probable systems of trackways, settlement and enclosure systems, and possible barrows as well as possible. Two scheduled monuments have been surveyed and archaeology confirmed in those zones. Some traces of burning activity have been recorded within Section D and might reflect closely undated production activity perhaps connected with salterns. Multiple anomalies throughout the site have been classified as unclear in origin because it has not been possible to definitively determine whether these anomalies are the result of archaeological, agricultural, or natural processes. Modern and historic agricultural activities have been identified across all sections of the survey area and represent former historic mapped field boundaries, ridge and furrows regimes, modern ploughing and drains.
