Magnetics Investigations
The magnetometer is a proven rapid-reconnaissance tool used to locate buried ferromagnetic objects and to investigate subsurface geologic features.
Anomalies in the earth's magnetic field, not attributable to known cultural features, may represent buried underground storage tanks, drums, utilities, or debris containing ferromagnetic materials. Magnetics anomalies are best detected by measuring the magnetics field intensity at regularly-spaced points (on a grid) throughout the area of interest. By plotting the location and magnetics field strength of each sampling point, a contour map can be generated to determine the location of magnetically anomalous areas.
The character of a magnetics anomaly can suggest the size, shape, and orientation of its source. This information allows a follow-up investigation, using GPR, terrain conductivity, utility-locatiion, and/or excavation methods, to be precisely focused.
