This thematic issue focuses on theoretical and experimental studies on problem of internal waves in the ocean. Articles are devoted to data of observation of internal tides in the northwestern part of the Pacific Ocean, as well as the results of study of the internal waves transformation of the Black Sea and the Sea of Japan taking into account conversion of wave energy into turbulent energy and data numerical modeling of the observations of nonlinear internal waves on the Malin Shelf (North Atlantic); the results of laboratory experiments on transformation of nonlinear internal waves of the first and second modes over a slope; experimental confirmation of existence of the asymmetric soliton waves propagating along the boundary between homogeneous layers of different densities; the results of theoretical analysis of asymptotic field of internal wave in the far-field area, interaction of solitons of internal waves, new class of the Boussinesq equations for moderate amplitude internal waves, examples of solution inverse problems regarding restoration of the fine structure of density field based on data related to nonlinear internal waves.
2013, volume 6, issue 3
This thematic issue focuses on theoretical and experimental studies of internal waves in the ocean. Atricles are devoted to theoretical models of nonlinear internal waves, including a description of the interaction of large-amplitude solitons, as well as analysis of mechanisms of the internal waves generation on an underwater slopes and as a result of the barotropic-baroclinic interactions; the results of in-situ observations of internal waves in the White and Black Seas; models of nonlinear surface waves and spectra of capillary turbulence required for analysis of radar images of internal waves.
2013, volume 6, issue 4
This thematic issue focuses on aquatic ecosystems problems. Atricles are devoted to the reproduction of marine ecosystem functioning and the larval distribution of commercial fish species in the Canary upwelling; storm surge modeling and turbidity modeling; transport of bottom sediments in the Neva Bay; problems of adaptation and testing of an effective data assimilation scheme of temperature and salinity of water in anoperational system of short-term forecasting of The Gulf of Finland; impact assessment of the Beloyarsk NPP on hydrothermal regime of The Beloyarski reservoir. The unifying element of all the articles is the solution approach: three-dimensional hydrodynamic modeling, which includes the marine ecosystem model in a number of studies.
