Basing House Spring Survey – Week 2 Day One

After a few weeks out of the field, the staff and students from the University of Southampton arrived back at Basing House to start the geophysical survey component of the fieldwork. A mix of third year students from Archaeology and Oceanography, Erasmus students and postgraduates headed out to the site. Chris Elmer again gave the group a tour of the site, while supervisors commenced gridding out the site using Smartnet GPS. The group were then divided into teams to carry out magnetometry, resistance survey, GPR and magnetic susceptibility.
