Abstract
A theoretical and an experimental study relating to the modeling of sound propagation in the upper ocean layers comprising bubble clouds has been performed using bubbles of various size in freely moving clouds produced in a laboratory test tank. The dynamical qualities of bubble clouds, due to the spatial and temporal variability of the void fraction, and the bubble size distribution in the horizontal and vertical directions have been taken into account. It is shown, that the acoustical properties of bubbly layers strongly depend on the frequency and the duration of acoustical signals propagating through the layers, on the void fraction of the layers, and on the resonance and the dispersive properties of the bubbly layers.
