Author: Pedro Luis Kantek Garcia Navarro Affiliation: CELEPAR Title: AN EVOLUTIONARY APPROACH IN MAGNETOTELLURIC INVERSION Text: Magnetotelluric inversion is the reconstitution of the pattern of underground geolectric conductivities out of an incomplete and noisy set of measurements of the electromagnetic field at various points of the surface, and at various frequencies. In the forward problem...

This paper reports an analysis of electromagnetic data from a site occupied on the floor of the Tasman Sea during an Australia-U.S. research program, the Tasman Project of Seafloor Magnetotelluric Exploration. This site (37ø33'S, 155ø58'E, depth 4450 m) is in the central portion of the Tasman Sea, and near both a fossil spreading ridge and the Tasmantid Seamount Chain. The extensive electric an...

the deep internal structure of the crust can be determined using appropriate seismic and electromagnetic methods. the natural source magnetotelluric (mt) method is the most suitable electromagnetic technique for probing into the deep crust. a long period magnetotelluric data set obtained in the southern chilean andes is investigated in this paper. dimensionality analysis shows that the data may...
