Archaeological Surveys and Excavation

Archaeological Prospectors primarily uses 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.
