Theoretical calculation of electromagnetic field generated by ocean waves

According to the Maxwell electromagnetic theory, motion of ocean waves will generate electromagnetic field.On the basis of a simple mathematic- physical model, the distribution of the electromagnetic field in the ocean is calculated.Results show that the electromagnetic field strongly depends on the period and amplitude of ocean waves.Within 100 m depth the amplitude of the magnetic field is in the order of nanotesla.The electric field is a few microvolts permetre.In the same depth, the magnetic field presents a near-linear tendency with the ocean wave depth.For the electric field, a maximum value is observed, which moves to the long period direction with the depth increase.The electromagnetic field is a major reason to influence the accuracy of the marine electromagnetic prospecting data.
