Description

The site is located 3km northeast of the centre of Newark, on the north side of Lincoln Road. The magnetic survey was carried out using a dual sensor Grad601-2 Magnetic Gradiometer manufactured by Bartington Instruments Ltd. This records subtle changes in the magnetic field resulting from differing features in the soil. Changes as small as 0.2 nanoTesla (nT) in an overall field strength of c. 49,000nT can be accurately detected using this instrumentation, although in practice instrument interference and soil noise can limit sensitivity. Readings were taken at 0.25m centres along traverses 1m apart. This equates to 6400 sampling points in a full 40m x 40m grid. The Grad 601 has a typical depth of penetration of 0.5m to 1.0m although a greater range is possible where strongly magnetic objects have been buried in the site. The survey recorded three parallel linear features which possibly form the remains of ridge and furrow cultivation or more modern activity such as land drains. The survey also recorded discrete positive anomalies across the field which could possibly represent pit like features. However, these are somewhat isolated and are difficult to interpret on the basis of form alone and difficult to rule out a more natural resolve. Other features form modern temporary road, and magnetic disturbance.
