In 2010 a pilot geophysical survey was carried out over two days to test the potential of geophysical techniques in this area. A Bartington fluxgate gradiometer was used in grids of 30 x 30m over an area of approximately 1.2 hectares. The sample resolution was 1 x 0.25m (3600 samples per grid). Preliminary results indicated that, whilst large scale features were clear (e.g. a rectangular structure, relict river channel and barrow), this resolution was not sufficient to identify the smaller features likely to be associated with monuments of the type identified through aerial photographs. Higher resolution survey, therefore, followed in 2011.
