Geophysical survey by R. Wardill (FAG, ECC) at Great Chesterford, 1996 - EEX52683

A gradiometer survey was undertaken on three hecatres of land inside the boundaries of the Roman town. The area chosen for the survey encompassed a region of dense crop-marking and the projected convergence of the town's three major roads. The primary aim of the survey was to determine the extent of buried features and provide an indication of their preservation and character. The project was conducted as a pilot study to evaluated the suitability of the geology for magnetometry and it is oped more extensive survey will be applied to the settlement and its environs. The three hectare survey area was aligned with the OS national grid nd sub-divided into 20m x 20m squares. Data was collected within this area at a sample interval of 0.5m and a traverse separation of 1m. The survey was carried out ise a Geoscan Research FM36 Fluxgate Gradiometer and ST1 Sample Trigger.
