Topographic survey as well as a higher resolution gradiometry survey were carried out in 2011, over four days. The topographic survey utilized a Leica Differential GPS (GPS900) to produce a detailed contour survey in OS national grid at a resolution of approximately 1m. The survey covered an irregular area of just over six hectares. The geophysical survey was carried out with a Bartington fluxgate gradiometer in grids of 30 x 30m, at a resolution of 0.5 x 0.125m (giving a total of 14,400 sample measurements per grid). Forty-seven grids were completed, covering a total area of 4.23 hectares. The gradiometer survey identified several anomalies of interest, including some possible post-pits of the cursus, a previously unidentified round barrow, and a rectilinear magnetic anomaly of unknown origin.
