Geoscan MSP25 with FGM650 gradiometer

The last few weeks has seen several successful surveys using the Geoscan MSP25 resistivity cart with additional gradiometer for the collection of simultaneous magnetic data. High resolution datasets have provided detail over two Roman sites with data captured through brambles in woodland where GNSS linked cart data and handheld surveying would have been impossible.

Magnetometry locates 'Band of Brothers' huts
Magnetometry carried out by Archaeological Surveys Ltd at Aldbourne, Wiltshire, has successfully located anomalies relating to Nissen huts used by Easy Company of the 2nd Battalion of the 506th Parachute Infantry Regiment of the 101st Airborne Division of the US army preparing for D-Day. Subsequent excavation, as part of Operation Nightingale, revealed concrete pads forming the foundations of one of the huts along with finds dating to the use and occupation of the site.

Magnetic debris is located by virtually all magnetometry surveys and often dismissed as modern topsoil junk. However, we shouldn't be too hasty in considering this material insignificant, it represents something and perhaps could be the only archaeological evidence of a past event, activity, settlement, etc. This article considers sources of magnetic debris and what sort of archaeological information may be derived from it.

Early settlement at Tysoe, Warwickshire.
Magnetometry undertaken at Tysoe, Warwickshire in 2017 and 2018 has revealed further evidence for extensive Romano-British and prehistoric settlement. Several sites previously identified by fieldwalking in the 1990s, and geophysics in 2010/2011, were chosen for additional wide area magnetometry survey. The results indicate numerous enclosures, field systems and track ways surrounding core settlement areas. The complexity of many of the sites infers long periods of settlement, possibly from the Bronze Age to the end of the Roman period.
