Detailed fluxgate gradiometer survey was undertaken by Britannia Archaeology Ltd over one field (c.3Ha) in March and April 2014. A fairly narrow range of anomalies were recorded within the dataset, some of which have an archaeological potential. Isolated dipolar ('iron spike') responses were most numerous were probably caused by the introduction of modern ferrous cultural debris into the topsoil during manuring and through loss, rather than resulting from the presence of buried archaeological artefacts. Six areas of magnetic disturbance were recorded, those on the boundary are likely to have been caused by the metal fence that encloses the field, while those to the east record the presence of electricity poles that bisect the field on a north-west to south-east alignment. Seventeen weak positive discrete and linear anomalies were recorded that are perhaps indicative of natural changes within the superficial geology, however an archaeological origin cannot be dismissed. Six broad weak dipolar anomalies, at least three of which are of a linear nature, were also recorded . These anomalies have been interpreted as remnant riverine deposits (palaeo-channels) that have gradually been backfilled by plough-action or silted up over time. These readings may also indicate the presence of deposits with a humic (potentially peat) content. Seven positive discrete anomalies indicative of archaeological rubbish pits were also recorded, however a geological origin cannot be ruled out.
