Electromagnetic induction in a spherical earth with non-uniform oceans and continents in electric contact with the underlying medium—I. Theory, method and example

SUMMARY This paper presents basic principles of the iterative-dissipative method and main points of its numerical realization. A spherical earth model consisting of a thin non-uniform surface layer being in galvanic contact with an underlying stratified medium is considered. The current system induced by a uniform magnetic field in the model with a realistic distribution of surface conductance is calculated. It is shown that leakage currents are significant even for the earth model with a highly resistive crust and upper mantle.
