Transverse Total Magnetic Field Gradiometer Marine Survey in Hawaii: The Quasi-Analytic Signal Approach and Multi-Channel Total Field DIPOLE MODELING

In this paper we present two techniques for Transverse Gradiometer (TG) data processing and<br>their practical application. Using our method, the transverse gradient is measured using dual sensors.<br>The longitudinal gradient is obtained using profile data history and the vertical gradient component is<br>computed synthetically based on 2-D potential field theory using the Total Field along the profile.
