Abstract: |
The cart-based gradiometer system used a Carlson BRX7 RTK GNSS instrument, which receives corrections from a network of reference stations operated by the Ordnance Survey (OS). Such instruments allow positions to be determined with a precision of 0.02 m in real-time and therefore exceeds European Archaeologiae Consilium recommendations (Schmidt et al. 2015).
The detailed gradiometer survey was conducted using four SenSys FGM650/3 magnetic gradiometers fixed horizontally 1 m apart on a non-magnetic cart with an effective sensitivity of 0.03 nT. The detailed gradiometer survey has been successful in detecting the remains of the mapped post-medieval hamlet of Langacre including roadways, ditches, field boundaries, buildings and drains.
Various large linear features have been identified across the survey area which correspond with roadways, ditches and field boundaries recorded on historical OS mapping (1887 & 1904).
One possible archaeological feature has been identified in the centre of the site. It is considered likely to be an unmapped field boundary, however alternative earlier origins cannot be ruled out.
Numerous magnetic trends have been identified in the north and south of the site. These are likely to relate to agricultural activity and drainage features. Ferrous anomalies have been identified across the site considered to relate to the hamlet of Langacre as well as the more recent continued agricultural use of the field. |
