DESCRIPTIVE ABSTRACT Process and apparatus for measuring an electric field in a conductive medium. A pair of electrodes (12,14) makes it possible to channel a current density creating the current which induces a magnetic field in one or more induction coils (16a,16b). This magnetic field is measured with the aid of one or more magnetometric transducers (28a,28b). The electric/magnetic transfer rate of the coils and the conductivity of the conductive medium are known, so that the value of the electric field is deduced on the basis of Ohm's law. The local magnetic field is previ- ously measured so as to take account thereof when measuring the induced magnetic field. Application to submarine electromagnetic measurements. (Fig. 2)
