Electromagnetic Background Noise in the Ocean Due to Geomagnetic Activity in the Period Range 0.5 to 1000 Seconds

Abstract

A summary is given of some of the characteristics of geomagnetic micropulsations. Based on a knowledge of micropulsation data measured at surface land stations, expressions are presented for obtaining estimates of the horizontal and vertical components of the electric and magnetic fields in the open ocean in the period range of interest, 0.5 to 1000 sec. Numerical results are presented for a seawater layer over an earth bottom. Perturbations in the open ocean field components by the proximity of a coastline are discussed.
