Special Issue Information

Dear Colleagues,

This Special Issue is devoted to the study of the physics of generation, dynamics, transformation of different-scale fields of the world ocean and their interaction, including different-scale hydrophysical fields (wind waves, swell waves, internal waves, seiches, freak waves, tsunamis, infrasound signals of typhoons, etc.), hydroacoustic fields of natural and artificial origin, and biological fields of communication and location origin. Of particular interest are the physical mechanisms of interaction of different-scale hydrophysical wave fields, the result of which is the appearance of a third field—for example, the occurrences of abnormal waves as a result of the interaction of swell waves and wind waves, infragravity waves, and swell waves. Much attention will be paid to the interaction of multiscale hydrophysical fields and hydroacoustic fields of artificial and natural origin. Research will also be devoted to the study of the influence of different-scale hydrophysical and hydroacoustic fields on biological objects. Especially interesting are the problems of studying the physics of generating electromagnetic fields of the world ocean in the dynamics of the hydrophysical and hydroacoustic fields. When studying all these processes, it is necessary to take into account the contribution of neighboring geospheres to the different-scale fields of the world ocean. Part of the research is aimed at developing installations and methods aimed at contact and remote monitoring of the studied phenomena.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

The paper presents the results of processing recordings of abnormal signals, which originated during the eruption of Hunga Tonga-Hunga Haʻapai volcano, and were registered by a laser nanobarograph and two laser strainmeters; there were three meters of sea-level variations, located in the Sea of Japan, and twelve meters of sea-level variations, located in the Pacific Ocean. Acoustic-gravity Lamb waves, generated in the atmosphere, caused disturbances of similar periods in the Earth’s crust, which were registered by laser strainmeters. Atmospheric impulse and Lamb waves during their propagation over the Pacific Ocean and the Sea of Japan initiated meteorological tsunamis in their waters, at periods corresponding to the seiches (Eigen oscillations) of registration stations’ location areas. In the records of all sea wave recorders, we did not find signs of a classical tsunami origination, and in the records of laser strainmeters, we did not find signals corresponding to seabed displacements at the point of the volcano explosion that led to the formation of a classical tsunami.

To study the specific features of free surface oscillations in the northwestern part of Posyet Bay (the Sea of Japan), a series of experimental works using an installation with a laser meter for measuring hydrosphere pressure variations were carried out in 2012 and 2014. In the course of the joint analysis, measurement results for oscillations with periods of 10–30 min and the results of calculations using a numerical model of shallow water with a difference approximation on an irregular triangular space grid, datasets of the space–time parameters for the resonance oscillations of the studied water area were obtained. The results of the numerical simulations confirm the manifestation of the resonance properties of Novgorodskaya, Expedicii, and Reyd Pallada Bays water areas on the oscillations singled out during the experimental studies. The positions of the peaks on the model resonance curves are consistent with the positions of the clearly pronounced peaks of the energy spectrum in the field data. Full article
