... incorporates advantages from two inversion strategies. Magnetic amplitude data are first inverted to recover an effective susceptibility model, providing information about the geometry and extent of the magnetic anomaly. The effective susceptibility model is then used to constrain a Magnetic Vector Inversion...

Jointly inverting the amplitude data with satellite gravity gradiometry data further helps overcome the adverse effect from unknown directions of magnetization. Simultaneously, the amplitude data also helps...

... the extracted lines. As a proxy for boundary detection we first calculate the mag- netic amplitude data because of their anomaly symmetry and weak dependence on inclination (Nabighian, 1972; Stavrev and Gerovska, 2000). In contrast to the com- monly used reduction to the pole (RTP) data, amplitude data...

... remanence and self-demagnetization, the total magnetization can have an orientation different from the induced field direction which precludes the use of traditional inversion methods. To overcome this problem, the magnetic amplitude data that are weakly dependent on the magnetization direction was inverted...

... these challenges, we propose a strategy through the joint use of the equivalent source technique and 3D amplitude inversion to perform 3D magnetization inversions. Equivalent source processing is used to calculate the amplitude data in the space domain since use of the wavenumber-domain is difficult due to large...

... statistics relating to amplitude data and associated inversion has not been well developed, hindering the ability to properly estimate the data misfit associated with an inverse model and therefore the model itself. To overcome these challenges, we investigate amplitude error statistics. amplitude...
