Magnetotelluric Sounding of the Interior of Venus
Introduction. Electromagnetic (EM) sounding has been widely used to reveal earth structure from depths of meters to hundreds of kilometers [e.g. 1-5] and has also probed the deep interiors of the Moon [e.g. 6-9] and the Galilean satellites [10]. The mag-netotelluric method [MT: 11,12] enables natural-source soundings from a single platform, without any external measurements or prior knowledge a...
متن کاملA Seafloor Magnetotelluric Sounding in the Tasman Sea
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...
متن کاملMagnetotelluric Sounding of Terrestrial Planet and Satellite Interiors
Introduction. Electromagnetic (EM) sounding of the Moon and the Galilean satellites has yielded important insights on the interior structures of these bodies [e.g., 1-7]. These investigations measured magnetic fields only and required auxiliary information on the nature of the source fields. The magnetotelluric (MT) method, by measuring both magnetic and electric fields, can perform soundings f...
متن کاملMagnetotelluric analysis using Mohr circles
The Mohr circle, most commonly met in the analysis of mechanical stress, is used to depict magnetotelluric impedance information, taking the real and quadrature parts of magnetotelluric tensors separately. The magnetotelluric concepts of two-dimensionality, three-dimensionality, skew and anisotropy are then all given quantitative expression on a diagram, as are various magnetotelluric invariant...
متن کاملReview paper: Instrumentation for marine magnetotelluric and controlled source electromagnetic sounding
We review and describe the electromagnetic transmitters and receivers used to carry out magnetotelluric and controlled source soundings in the marine environment. Academic studies using marine electromagnetic methods started in the 1970s but during the last decade these methods have been used extensively by the offshore hydrocarbon exploration industry. The principal sensors (magnetometers and ...
