description
TerraDat is a UK based specialist geophysical ground exploration company that operates worldwide. Geophysical surveys provides a rapid, non-invasive ground investigation tool that has many applications ranging from locating buried manmade structures through to characterising geological and hydrogeological features. This TerraDat Technical Note deals with how geophysics can benefit a comprehensive understanding of the subsurface, with specific application to shallow archaeology.

TerraDat’s archaeological capability has been recently enhanced through the use of a specialist magnetic gradiometry carrier system. This system utilises eight Foerster FEREX CON 650 gradiometer probes mounted on a towed rig. Real-time, sub-centimetre accurate positioning is provided by a Trimble 5700 RTK GPS. The rig is towed across the survey area behind a 4x4 vehicle or ATV acquiring swaths of data up to 3.5m wide. The probes are spaced 0.5m apart giving twice the resolution of a conventional gradiometry survey.
In optimal field conditions, the new system allows acquisition rates of up to 40 hectares per day - significantly reducing survey costs and time over a conventional walked survey.
