Triaxial Gradient Mag

For large surveys, or for where gradiometer data is advantageous, Axiom flies manned helicopters and provides gradient magnetic surveys with three specially designed potassium vapour magnetometers mounted in a triaxial array. The data from the three individual sensors allows us to measure the horizontal and vertical gradients of the magnetic field. Horizontal gradient measurements provide details about the lateral extent of subsurface anomalies located between survey lines. Vertical gradients can assist significantly in identifying geologic/ structural contacts and near-surface targets. Measuring these gradients directly is a significant advantage when compared to a single sensor of a conventional total field system.
