1. A method for determining a component of electric field response of the Earth'"'"'s subsurface to a time-varying electromagnetic field induced in the Earth'"'"'s subsurface, comprising:

  • measuring electric field response along a nonlinear pattern on at least one of the Earth'"'"'s surface and the bottom of a body of water;

    measuring magnetic field response in three directions along the nonlinear pattern on at least one of the Earth'"'"'s surface and the bottom of the body of water; and

    determining an electric field response in a direction normal to the measured electric field response using the electric field response and magnetic field response measurements.
