This paper describes as series of experiments designed to obtain estimates of the spatial bubble characteristics within a surface ship wake. By using measurements of the across the wake time dependent transmission loss at a single depth, estimates of the excess absorption due to the bubbles in the wake were obtained as a function of wake age and frequency. Using the theory of absorption in a bubbly medium, estimates of the bubble number densities as function of wake age, and acoustic… CONTINUE READING
