Airborne Electromagnetic Survey
BestPractices In the case of airborne systems, the receiver coils are usually in a towed bird and the transmitter may be a large coil encircling a fixed wing aircraft, e.g. INPUT systems, or one or more small coils in the same bird that houses the transmitting coils  +
DataAcquisition A primary man-made alternating magnetic fi
A primary man-made alternating magnetic field is established by passing a current through a coil. The field is measured with a receiver which consists of a sensitive electronic amplifier and meter or a potentiometer bridge. If the source and receiver are flown over a more conductive zone, such as an area with higher metallic content, a measurable secondary magnetic field will be created. This secondary magnetic field is compared to the original and is usually reported proportionally to the primary magnetic field. For airborne electromagnetic systems, the receiver coils are usually in a towed bird and the transmitter may be a large coil encircling a fixed wing aircraft. Or another set up is with one or more small coils in the same bird that houses the transmitting coils.

Pitfalls Some areas are not appropriate for airborn
Some areas are not appropriate for airborne electromagnetic surveys. These include semi-arid areas, particularly with internal drainage, and tidal coasts and estuaries. Also the background conductivity can influence the accuracy of the results. For example, weathered maific flows can provide strongly conductive backgrounds masking other signals. There are multiple factors that can influence the detectability of the conductor which need to be accounted for when analyzing the data. These include among many coverage, resolution, and the penetration depth of the system.
