Methods
Magnetic Profiling
This passive technique involves measuring the total amplitude of the Earth's magnetic field using specific equipment. Ferrous objects have considerably different magnetic field amplitude than their surrounding environment. Therefore, the amplitude of the magnetic field increases or decreases depending on the orientation and shape of the target of investigation. GeoProfessional uses modern, ultra sensitive magnetometers and gradientometers, that can measure the amplitude of the magnetic field to within as little as 0.01nT.
Measuring the vertical gradient of the field is very useful in near surface investigation because it can improve the resolution of individual anomalies in a general anomal area. In addition, the high gradient tolerance of our equipment makes them usable in urban areas that are generally culturally noisy. The magnetometers / gradientometers used are extremely sensitive and are able to measure the amplitude of the magnetic field with great accuracy, detecting small metallic objects like unexploded ordnance and more subtle magnetic anomalies caused by buried construction work (walls, foundations, tunnels, etc.).
The results of the magnetic data interpretation are plots that present the anomal magnetic areas that can be monopolar or dipolar, depending on the orientation of the target. If the buried objects are closely spaced, the plot can present a general area of irregular anomalies.
