SNN105069 - Geophysical Survey Report - Wakerley, Northamptonshire

A geophysical survey was conducted over 132ha of agricultural land near Wakerley. The magnetic susceptibility survey revealed that the highest areas of enhanceent were in the east, although much of the site was moderately enhanced. A detailed magnetic survey carried out over 32ha within eleven areas, revealed a density of positive linear, rectilinear and curvilinear anomalies in the east of the site, several of which can be interpreted as rectilinear enclosures. Areas of magnetic debris and several stong discrete dipolar anaomalies are likely to be associated with iron working. The presence of positive area anomalies in the east of the site may be a response to the magnetically enhances fill of channels. It is unclear whether these channels are purley geomorphological features or if they are associated with iron extraction and working.
