An instrument capable of measuring magnetic gradients as encountered in airborne magnetometer operations has possible applications as an interpretational aid. Its usefulness, particularly for qualitative analysis, will be discussed briefly. The design of a spatial-type airborne gradiometer of adequate precision can be shown to be quite impractical. An instrument based on the time derivative of the magnetic intensity variations provides a useful alternative and is described.
