Land off The Forty/Chelworth Road, Cricklade, Wiltshire, Magnetometry Survey Report

Key Points

To assess subsurface features at the Land off The Forty/Chelworth Road using magnetometry.
Conducted magnetometry survey using SENSYS MAGNETO MX V3 system.
Survey covered two areas: Area 1 north of Chelworth Road and Area 2 south of The Forty.
Used six fluxgate gradiometers spaced 0.5m apart, collecting data at 20Hz.
Identified evidence of former ridge and furrow cultivation in both areas.
Detected weakly positive linear and discrete anomalies, with no coherent interpretation possible.
Noted positive curvilinear anomalies in Area 2, possibly linked to animal feeders, but not confirmed.

Abstract

Detailed magnetometry was carried out within two areas, Area 1 to the north of Chelworth Road and Area 2 to the south of The Forty, Cricklade. The survey was conducted using a hand-pushed SENSYS MAGNETO MX V3 6 channel cart-based system. The instrument has 6 fluxgate gradiometers (FGM650) spaced 0.5m apart with readings recorded at 20Hz. Both parts of the site contain evidence of former ridge and furrow cultivation and also a number of weakly positive linear and discrete anomalies; however, they generally lack a coherent morphology and cannot be confidently interpreted. The eastern area (Area 2) contains a number of positive curvilinear anomalies, that could be associated with the former location of animal feeders, but this is not certain.
