“…Simultaneously with the sea expedition, the coastal group worked with the participation of specialists from two organizations and professional divers (E. V. Verbitsky and R. E. Verbitsky). The research in the Black Sea [7] provided extensive synchronous data to characterize the current state of the most vulnerable psammophilic benthic communities dominated by the Donax trunculus, Lucinella divaricata, Spisula triangula, Chamelea gallina species at depths of 2-20 m, as well as pelophilic communities at depths up to 200 m [18]. The mouth areas of small rivers at the junction of the river -the sea were studied in detail.…”

Study of natural and anthropogenic processes in the southern seas of Russia is a priority task of the Southern scientific center of Russian Academy of Sciences. Annually for 15 years, the Southern scientific center of RAS carried out sea expeditions in the south of Russia. The year of 2017 was marked as a 10-year anniversary of the first expedition of the R/V Deneb in the Azov and Black seas. During a five-year period from 2012 to 2016, 36 complex expeditions in the Azov and Black seas were carried out by R/V Deneb; the oceanographic database was enriched with the data of 3500 oceanological stations, more than 11,000 samplings were done at more than 900 complex hydrobiological stations. The expeditionary materials enlarged the oceanographic database of the Southern scientific center: the field and archival data permitted to assess long-term dynamics of organic matter and carbon, the Azov Sea transparency and salinity and to calculate the characteristics of small-scale variability of temperature, salinity, internal waves and level fluctuations in the Azov and Black seas. The research in the Black Sea provided extensive synchronous data which characterize current state of the most vulnerable psammophilic benthic communities at the depths of 2-20 m. The estuaries of small rivers at their junction with the sea were studied in details. The new data on distribution and quantitative characteristics of jelly-like-, phyto-and pico-plankton over the whole shelf area of the Russian sector of the Black Sea is obtained. The Black Sea population of newcomers -Holland crabs (Rhitropanopaeus harrisi tridentate) -living exclusively in the sea canyons with unstable salinity was studied. The metagenomic approaches applied to study the plankton communities in the Azov and Black seas, were used to obtain new data on diversity and structure of marine bacterial communities. The oceanological observation data on the environment conditions in the Azov and Black seas are annually directed to the Hydrographic department of the Black Sea Navy of Russian Federation where it is used in the field service.

“…The expedition carried out a detailed (with a 5-meter increment in depth) sampling of soil and benthos in areas exposed to the strongest coastal discharge in July 2012. It made possible to assess the effects of catastrophic flooding on coastal marine ecosystems [18].…”

The paper covers the modeling of hydrodynamic processes in shallow waters in the presence of pollutants of various types, as well as areas covered with plastic waste, including nano- and microplastics. The simulation performed using new and effective mathematical instruments, including assimilation methods of measurement data, restoration of the state function, diagnostics of quality of the developed models, the research the sensitivity of models to variations in input data, the integration of models with various scales. Interrelated non-stationary, spatially inhomogeneous mathematical models of hydrodynamics and biological kinetics of shallow waters were developed and numerically implemented. They describe non-linear processes of hydrophysics, biogeochemical cycles, transport and transformation of suspensions and sediments with microplastic particles and other pollutants, absorption of it by zooplankton and fish, movement of plastic particles through food, the forecast of their impact on the main hydrobionts of shallow waters of the Azov-Black Sea basin, including the Azov Sea, Taganrog Bay, Gelendzhik Bay. The models take into account the heat and salt transport; the complex, dynamically changing water geometry; friction on the bottom and wind stresses; turbulent and advective heat and mass exchange in three coordinate directions; the Coriolis force; river flows; evaporation, temperature and oxygen regimes. They make it possible to improve the accuracy of hydrophysical processes modeling in shallow waters, to detect vortex structures of currents that can be a natural pollution traps, including microplastic. Based on a supercomputer, a complex of application has been designed and adapted for solving predictive problems of water ecology and water resources management.
