PRELIMINARY ANALYSIS OF ELF NOISE

Abstract

Preliminary results of analyzing extremely low frequency (ELF) electromagnetic noise recorded in Florida and Malta are presented. The results include wideband waveforms, power density spectra, amplitude probability distributions and probability distributions for the duration of the interval between noise bursts. The distinctly non-Gaussian nature of the noise is demonstrated in a variety of ways. (Author)
