Gassy sediments of shallow lakes are a source of permanent concern due to their contributions to sediment destabilization and global warming. In this study, a “microscopic” bubble model is suggested that describes shapes and sizes of methane bubbles in muddy aquatic sediments predefined by sediment mechanical properties. An effective media model specifying a bubble size distribution is designed based on the microscopic model. An acoustic approach for verification of this model is proposed. It is based on the estimation of the frequency dependence of sound reflection coefficient from gassy sediments, which exhibits the resonant behavior. An experimental implementation of the method is discussed.
