TL;DR: In this paper, the spectral properties of background internal waves (IW) were analyzed for two oceanic shelf regions (the Atlantic shelf of the United States and the Kamchatka shelf) and it was shown that the observed anisotropy of the IW field may considerably affect the lowfrequency sound fluctuations in the aforementioned regions and, in particular, may change the interference invariant of the sound field.

TL;DR: In this paper, the authors observed that the acoustic frequency shifts appear to be strongly dependent on the modes of the sound field and analyzed the overall interference pattern and found which part is more sensitive either to the surface tide or the internal waves.

TL;DR: In this article, a phenomenological model of long-range reverberation in a shallow sea is developed to describe the statistical characteristics and interference of the sound field scattered by bottom inhomogeneities.

TL;DR: In this paper, the possibility of controlling localized fields in multimode regular waveguides on the basis of the interference invariant principle is studied by numerical simulation, and it is demonstrated that, by tuning the radiation frequency of an array without changing the initial field distribution at the aperture, it is possible to perform the scanning by a focal spot in a waveguide.

TL;DR: In this paper, the sensitivity of the remote method of reconstructing the frequency spectrum of a water medium perturbation from the measured frequency shifts of the sound field interference peaks is investigated.
