EDO8096 - Wimborne Minster; geophysical survey 2023

OASIS: 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. Project Results: A magnetometer survey of approximately 3.1 hectares of a 5.8 hectare site was conducted on land at Wimborne Minster, Dorset and did not record any results of archaeological interest. The survey identified linear trends, discrete anomalies and areas of increased response, all of an uncertain origin. Approximately 2.7 hectares of the land was at the time of the survey due to heavy overgrowth.
