Abstract

Fifty audiomagnetotelluric (AMT) measurements covering 10 KHz – 10 Hz frequency range have been carried out on the onshore portion of Almada basin, Bahia state. AMT data were recorded in two roughly orthogonal profiles and our approach interprets the AMT soundings using the first–order Tikhonov regularization 2D inversion method to estimate the resistivity distribution in the subsurface that explained the field observations to within a preset error.
