The geophysical survey covered an area of approximately 2.87 ha. The survey was undertaken using a Bartington Grad601-2 dual fluxgate gradiometer at 1m transverse and at 0.25m sample intervals using a zigzag transverse. The site grid was laid out using a Lecia Captivate with GS18/CS20 GNSS RTK Rover, with a grid size of 30m by 30m. A zero station with low magnetic susceptibility was established on site to correct for diurnal drift in the sensors. This calibration point was used consistently throughout the survey to maintain data accuracy. In April 2026, Cotswold Archaeology conducted a geophysical survey of part of the proposed route of the Wickham Market Pipeline, Hacheston, Suffolk. An area of 2.87ha was surveyed within the site. The survey identified a range of anomalies that have been classified as agricultural, archaeological, geological/natural, modern, and undetermined. Across the two fields that were surveyed, the southern field clearly contains possible and probable archaeological anomalies that form enclosures, field boundaries, pits, potential kilns/ovens, and a track/roadway, with some magnetic disturbance in the southern end of the survey area. Within the northern field there are fewer anomalies interpreted as potential archaeology due to the presence of geological/natural anomalies. The possible archaeological anomalies seem to be clustered in the southern end of the northern field. Due to the presence of the geological/natural anomalies there are several possible archaeological anomalies that have not been possible to interpret. The modern disturbance and geological/natural responses could also have distorted or obscured other minor archaeological features.
