This report represents an extension of the work described in an earlier report. It is an analytical study of the electromagnetic field in the ocean resulting from excitation over land by natural electromagnetic noise such as micropulsations or ELF atmospherics. The main purpose of the study is to determine the relative importance of electromagnetic energy entering the ocean via the air-water interface versus energy entering via the soil and ocean bottom. Emphasis in this report is placed on a comparison between the vertical and horizontal components of the electric field. Vertical profiles of the horizontal and vertical electric field vectors are plotted for several values of frequency, ocean depth, and the distance from the shoreline. Finally, a comparison is made with some experimentally determined values of the horizontal electric field.
