Geophysical Surveys

 

Archaeological Prospectors has over 15 years experience in the use of geophysical equipment and are educated/trained at the graduate level, to provide you with the highest quality surveys in the region. We primarily use the Bartington 601Grad fluxgate gradiometer with a 1m sensor separation. By doubling the length between sensors (compared with other popular fluxgate gradiometers), the Bartington 601Grad can detect minor features at a greater depth. Features are detectable to a depth of up to 3m below surface. Detectable features include: prehistoric hearths, artifact scatters, living floors, historic foundations, middens, privies, trails, roads, ditches, pits, pipelines, buried tanks, service conduits, etc.

Advantages

  • Very quick assessment of large areas, up to 4000m2/day,
  • Will detect most archaeological features,
  • Sensitive to small features,
  • Records data as frequently as every 12.5cm per traverse,
  • Focuses research to areas of prime interest or concern, reducing the amount of time spent in the field digging unnecessary test pits,
  • Non-destructive, ideal for culturally sensitive sites.

Applications

  • Pre-development archaeological assessment,
  • Archaeological research projects,
  • Mapping and defining site boundaries,
  • Intra-site assessment to focus excavation,
  • Forensic detection of clandestine graves,
  • Buried pipe & service conduit location,
  • Cultural Resource Management.
