On generation of sound by an internal bore

Internal bores are nonlinear internal waves that move toward the coast and have a characteristic steplike shape to their fronts. The bore is a frequent phenomenon for shelf zones of seas and oceans. The passage of the bore leads to a substantial change in the conditions of sound propagation in the sea medium and, generally, to the formation of a near-bottom sound channel. In this work, we theoretically consider another effect of the aforementioned phenomenon on underwater acoustics, namely, the generation of sound by the internal bore propagating over the bottom.
