Energy characteristics of the sound fields in the Barents Sea

Energy characteristics of the sound fields in the Barents Sea Abstract Experimental studies of the intensity structure of the sound field in the Barents Sea were carried out. The signal propagation path was ∼80 km in length, and the sea depth was ∼220–250 m. Pseudonoise signals generated in one-third-octave frequency bands with central frequencies of 1.25 and 3.15 kHz were used. The sound source was positioned at two different points: in the subsurface layer at a depth of 10 m and under the discontinuity layer at a depth of 100 m. The reception depths were 15, 100, and 200 m. The experimental results were compared with the results of ray calculations taking into account the wind waves and the parameters of the ground at the bottom. The latter parameters were obtained by classifying the data available from the literature. As a result of the analysis, a fundamental possibility was demonstrated to predict the intensity characteristics of the field structure in a shallow sea with allowance for the depth dependence of sound velocity and the parameters of the waveguide boundaries. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract Experimental studies of the intensity structure of the sound field in the Barents Sea were carried out. The signal propagation path was ∼80 km in length, and the sea depth was ∼220–250 m. Pseudonoise signals generated in one-third-octave frequency bands with central frequencies of 1.25 and 3.15 kHz were used. The sound source was positioned at two different points: in the subsurface layer at a depth of 10 m and under the discontinuity layer at a depth of 100 m. The reception depths were 15, 100, and 200 m. The experimental results were compared with the results of ray calculations taking into account the wind waves and the parameters of the ground at the bottom. The latter parameters were obtained by classifying the data available from the literature. As a result of the analysis, a fundamental possibility was demonstrated to predict the intensity characteristics of the field structure in a shallow sea with allowance for the depth dependence of sound velocity and the parameters of the waveguide boundaries.
