Abstract

Within the geophysical community there has been considerable interest in developing instrumentation for measurement of magnetic gradients and in developing processing strategies to effectively interpret the collected magnetic gradient data (see, for example, TLE's Magnetic Gradiometry special section in 2006). There have been significant advances in sensor technologies in recent years, and true magnetic tensor gradiometry using SQUIDS (Superconducting Quantum Interference DeviceS) may soon be in reach, at least in an experimental form.
