Magnetometer survey carried out over c. 337.2ha using hand-pulled, cart mounted and hand-carried GNSS-positioned bespoke fluxgate gradiometer system. Magnitude survey was commissioned to assess the subsurface archaeological potential of a c. 383ha area of land in Norfolk. A fluxgate gradiometer survey was successfully completed across 337.2ha, with the remaining c. 45.8ha being unable to be surveyed due to unsuitable ground conditions. At various points along the survey corridor probable and possible archaeological activity has been identified, including multiple possible rectilinear and subcircular enclosures, along with field systems, and related anomalies and features. Some of the anomalies which have been identified are in close proximity to cropmarks identified in the archaeological background and are likely caused by or are continuations of those, or similar features. Throughout the survey corridor, agricultural activity has been detected, including recent ploughing trends, former field boundaries, drainage features, and pre-modern cultivation, with evidence of quarrying also identified along the survey route. Additional anomalies have been categorised as being of 'Undetermined' origin; these are isolated, fragmentary, or ephemeral, and may be the result of natural variations, archaeological or agricultural activity. Natural variations have been identified throughout the survey area. Modern interference is generally limited to current field boundaries and buried services, overhead cables, and telegraph pole and pylons.
