A prod into the dark

Having a sense of what you're about to encounter is invaluable in archaeology. One way of exploring the depths of a site, before you sink a trowel into it, is through remote sensing. Aerial photographs can reveal crop marks, indicating the presence of ditches and buried structures. Other non-destructive, geophysical survey techniques, such as resistivity, magnetometry and ground penetrating radar, provide another way of testing what is beneath the surface.
David Hunter of Hunter Geophysics kindly offered to do a resistivity survey of the TARDIS. Braving another damp morning, we laid out 1m wide strips and surveyed the site.

The remains of the Historical Australia phase architecture, and emerging structures, limited the amount of readings we could take, but it will be interesting to see how the wide range of resistivity readings, particularly in the north of the site, compare with what we uncover in the coming days.
