Detailed magnetic survey (magnetometry) was chosen as the most efficient and effective method of locating the type of archaeological anomalies which might be expected at this site. All survey techniques followed the guidance set out by CIfA (2020) and the European Archaeology Council (EAC) (2016). Bartington Grad 601-2 Traverse Interval 1.0m Sample Interval 0.25m The only processes performed on data are the following unless specifically stated otherwise: Zero Mean Traverse This process sets the background mean of each traverse within each grid to zero. The operation removes instrument striping effects and edge discontinuities over the whole of the data set. Step Correction (De-stagger) When gradiometer data are collected in 'zig-zag' fashion, stepping errors can sometimes arise. These occur because of a slight difference in the speed of walking on the forward and reverse traverses. The result is a staggered effect in the data, which is particularly noticeable on linear anomalies. This process corrects these errors. A detailed magnetometer survey was conducted at Arden Green, Solihull, and it has identified magnetic disturbance associated with a former medieval / post-medieval moated site along with ridge and furrow cultivation, both of which are recorded as heritage assets on the HER. Linear anomalies of uncertain origin are most likely to be agricultural or modern, while areas of strong magnetic disturbance indicate areas of made ground and are probably related to the golf course which previously occupied the site.
