- Аннотация: The applicability of a passive acoustic method for monitoring bubble gas emissions in shallow water is being investigated. Experiments on the registration of audio signal generated by single gas bubbles with a diameter of 3–4 mm were conducted under laboratory and field conditions. Under laboratory conditions, one maximum in the frequency spectrum was observed, occurring at about 2500 Hz for bubbles of small diameter and 1570 Hz for larger bubbles. In situ experiments were carried out in Laspi Bay (the Black Sea). Several peaks in the frequency bubbles spectrum were shown: at 1550, 1100 and 600 Hz. The highest frequency recorded by hydrophone qualitatively coincides with the resonant frequency of a 4 mm diameter bubble calculated from the Minnaert equation.
