Smashing blog from Nicole Beale on the completed survey at Basing House, and a bit of a low-down on the techniques used, represented by abbreviations and three letter acronyms in my blog over the last few weeks. Enjoy!
Basing House Project
The undergraduates have finished working at Basing House for this Spring, and we’ll be back on site in a few weeks to collect more data for some of our postgraduate students who are using the site for various projects.
This is the team from Week 2. I can’t believe how much ground these guys covered! Thanks all!
I thought it might be useful to give you a rundown on the different tools that we were using to record the site during the topographic, building and geophysical survey, as we keep saying things like ‘mag’ and ‘GPR’ without explaining what any of them are!
In our next post, we’ll begin to share the results of the surveys, so do check back regularly, or subscribe to the blog for updates, using the link on the navigation to the right.
There are a few pieces of kit that we use for…

The second week of survey at Basing House finished on Friday in a spray of mud and rain, hailstones and inky cloud. What had promised to be a reasonable day quickly became unworkable, wet and cold. The teams set out for the final day of survey, focusing on completion of the magnetometry and resistivity in the area of the New House and outer bailey, and GPR over the outer bailey also. We abandoned the magnetic susceptibility to ensure that all hands were working on the res and mag. The rain set in and the GPR survey was the first to suffer, with the notebooks turning to mush.
Time for a weatherproof notebook!
The magnetometry continued, mopping up grids on the Civil War earthworks, and finishing the survey of the New House and outer bailey. Resistivity was completed in the Old House and the New House, although the team had suspicions that the wet weather would affect the results.

Rain? What rain?
We have had some really productive days on the second phase of survey at Basing House, with third year and postgraduate students from the University of Southamotin working hard, and carrying out resistance survey, magnetometry, GPR and magnetic susceptibility of the Old and New houses, and Civil War defences and the outer bailey. Spring also finally arrived today after single-figure temperatures and damp weather. Altogether today marked the best day of surveying yet.
Survey in the area of the outer bailey
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.
Team gridding out the site with the GPS
Magnetometry commenced in the area to the west and south of the ringwork and Old House, covering parts of the Civil War defences. Two Bartington Instruments gradiometers were used. The resistivity teams started work in the area of the Outer Bailey, surveying at 0.5m by 0.5m resolution. Continue reading
