Magnetometer and resistance surveys were undertaken near Adlingfleet, Lincolnshire, in response to a request from the Humber Wetlands Project (HWP). An extensive spread of Roman material, including some Samian Ware, had been collected during an HWP field walking assessment of the Ancholme and lower Trent valleys near to the confluence of the rivers Trent and Ouse. The geophysical survey carried out in 1996 successfully located a number of surviving archaeological features, including clear evidence of industrial activity, and thereby assisted the location of HWP assessment trenches. Further survey in 1998, to the north of the original area, located more magnetic anomalies of a similar type and intensity to those detected in the 1996 survey.
