Some preliminary work on the determination of the earth's electric conductivity structure through simultaneous measurements of the natural electric and magnetic fields is reported in this letter. Cagniard [1953] coined the name ‘magnetotelluric’ for studies of this type. The present work was confined to frequencies of .005 to 1 cps, having skin depths distributed through the crust. Magnetotelluric studies have been underway in the M.I.T. Geophysics Laboratory for several years. Neves [1957] studied two-dimensional effects, and more recently the measurements described here were made [Cantwell, I960]. Further field investigations are under way at this time, and will be incorporated in a more complete paper in the near future.
