MULTI-COMPONENT MARINE ELECTROMAGNETIC SIGNAL ACQUISITION METHOD
First Claim
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.

Abstract
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 is provided. The method includes 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. The method includes 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. The method further includes 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.
