Correlation characteristics of variations of the ambient noise level in the shelf zone of the Pacific Ocean

Correlation characteristics of variations of the ambient noise level in the shelf zone of the... Abstract Results of measuring normalized autocorrelation functions and frequency correlation functions of slow random variations in the ambient noise levels are presented. The measurements were carried out in the shelf zone of the Pacific Ocean, near Shikotan Island, at a depth of 130 m in the frequency range from 0.9 Hz to 11 kHz. The noise level’s variations were fairly synchronous in a wide frequency range. Their autocorrelation interval varied from 11 to 42 h for different frequencies, and the frequency correlation was no smaller than 0.77 within 2 decades.

Abstract

Abstract Results of measuring normalized autocorrelation functions and frequency correlation functions of slow random variations in the ambient noise levels are presented. The measurements were carried out in the shelf zone of the Pacific Ocean, near Shikotan Island, at a depth of 130 m in the frequency range from 0.9 Hz to 11 kHz. The noise level’s variations were fairly synchronous in a wide frequency range. Their autocorrelation interval varied from 11 to 42 h for different frequencies, and the frequency correlation was no smaller than 0.77 within 2 decades. The integral autocorrelation interval of the wind speed’s variations was 14.1 h.
