Recent measurements of naturally occurring electromagnetic (em) fields on the sea floor have demonstrated a prominent spectral peak at about 0.2 Hz. The fields associated with this peak are not correlated with natural em signals measured on land adjacent to the oceanic observing station but seem to be related to ocean surface waves having a frequency one half that of the spectral peak. It is proposed that the nonlinear interaction of opposed trains of surface waves (similar to the mechanism thought to be responsible for microseisms) generating fluid motion across the geomagnetic field causes the observed signal. Calculations are presented to substantiate this proposed mechanism. |
