STABILITY OF FREQUENCY-WAVENUMBER NOISE SPECTRA AT UBO

Abstract

Seven four-minute samples of the ambient noise were subjected to frequency-wavenumber (F-K) spectral analysis, in order to observe the range and character of variations in the F-K power spectrum. The observations are derived from the same normal population. The apparent variation in the underlying noise statistics or processes do not suggest gradual diurnal variations in the noise power, but large and apparently random interday fluctuations. (Author)
