Magnetometry - Geophysical surveys

Site Scan (Archaeological) Ltd utilise a Bartington GRAD-601-2 system. This technique can be used to identify both, geological and man-made features/structures within the soil. Due to the altered magnetic properties of the soil it is possible to locate landscape alterations (e.g. filled in ditches), and other archaeological activity (i.e. buildings and field systems etc.).

Applications

1. Archaeological site evaluation prior to acquisition or development.
2. When test-pitting is required due to planning policy (PPG16), an
   accurate locating of test-pits can be achieved.
3. Academic research of archaeological sites.
4. Integral element of Desk-Top and Environmental Impact Surveys in
   association with land management projects.

Advantages

• Cost effective in relation to both data produced and time scale.
• Responsive to numerous archaeological features (i.e. pits, ditches, earthworks, structural remains, kilns, hearths etc.)
• High resolution survey data
• High sensitivity to small features
• Traditional test-pitting methods only cover a small percentage of the
  site, whereas geophysical surveys can cover the entire site. This leads
  to greater security of corporate investment in development projects.
• A non-invasive method of data retrieval.
