This issue’s articles are devoted to the simulation results of surface М2 tidal currents near the archipelagos of Franz Josef Land and Svalbard as the elements of the Barents Sea dynamics; data of numerical experiment regarding flow around an underwater obstacles and interaction of surface and internal waves on the basis of non-hydrostatic model; hypothesis of existence of the standing-translational gradient-vortex Rossby waves, their assessment based on satellite altimetry; analysis of statistical data on enthalpy changes of the ocean during the 1955-2009; the mean sea level variability and some hydrometeorological characteristics of the eastern part of the Gulf of Finland from 1958 to 2009; the results of in-situ measurements and spectral analysis of ebb under conditions of extreme wind, wind waves and swell during passage of a cyclone over the northern part of Sakhalin Island; two new variants of the hydro statistical density recalculation method to solve problem of increasing the accuracy of seawater density measurements based on signal processing of three or four tightly bound pressure sensors; features of adaptive receiving of plane-wave broadband signals taking into account technical- and physical-related factors.
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.
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.
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.
