Site Event/Activity record ESF27161 - Geophysical and Topographical Survey - Dog Kennel Field

Between the 19h October and the 21st October 2009, a geophysical and topographical survey covering approximately 3.1 hectares was undertaken in the area of Dog Kennel Field (henceforth 'the site' or Area C) to the east of Naunton Hall, Rendlesham, Suffolk (NGR TM 329 532) (Fig. 2). This formed the second season of work at the site, with initial surveys the previous year focusing on land to the north and south of Naunton Hall. The conditions during the survey varied throughout the day but were broadly consistent for the length of the fieldwork, being cold and overcast in the morning with increasing sun during the later part of the day but dry throughout. The harvested crop in Area C was reduced to short stubble which presented no difficulties for the conduction of the survey. The ground cover was consistent across the entirety of Area C. The survey area was limited by the presence of a series of structures and metal enclosures associated with Kennel Cottages in the west of the survey area, and by a strip of maize bird cover in the east. The magnetometer survey was undertaken using a Bartington Grad 601-2 dual sensor vertical component fluxgate gradiometer. This equipment allowed the survey to be conducted rapidly in the open area. Readings were taken at 0.25m intervals along traverses of 1m spacing. The geophysical survey grids of 30m by 30m following the same north-south alignment utilised previously were set out using a Leica Smart Rover GPS which was also used to tie the survey in to known features in the landscape, in this instance field boundaries. The Leica Smart Rover GPS system was utilised to record elevation data enabling a close interval contour model of the site to be produced. The production of the contour survey involved recording a series of spot heights along c. 5m traverses across the terrain with an increased number of readings taken in areas showing visible variations in elevation (S1).
