“…For example, a period from 2010-2018 is distinguished, for which freshening is observed in the central part of the Sea of Azov in spring and summer, except for cases of slight salinization in May. This is in good agreement with the course of normalized surface salinity anomalies according to in situ data during this period [17][18][19] .…”

In this work, we obtained the results of salinity recovery in the Sea of Azov for the 19-year period 2000-2018, obtained on the basis of a regression model using regional biooptical parameters according to MODIS-Terra/Aqua data. To analyzed the deviations of the average monthly values of the restored salinity relative to climatology for 1913-2018. The results of the estimating of average monthly salinity anomalies in the spring and summer seasons relative to the climatic fields of salinity in the maps. Based on the comparison of the average monthly values of the reconstructed and observed in situ salinity, conclusions are drawn about the feasibility of using a regression model obtained by direct averaging of regression coefficients. The most effective regional bio-optical parameter determined, in terms of the best correlation of reconstructed salinity versus in situ measurements.

“…According to long-term average data, 49.2 km 3 of water flows out of the Sea of Azov annually, and 33.8 km 3 of Black Sea water per year enters it. The resulting runoff of water from the Sea of Azov to the Black Sea, on an average long-term value, is 15.5 km 3 /year [40][41][42][43][44].…”

Ferrous metallurgy enterprises have a negative impact on the air, soil, and water environment. The activities of metallurgy enterprises include a wide range of production processes (from the extraction of metals from ores to obtaining finished products) and is associated with the formation of a large amount of waste. Industrial wastewater discharge is the main source of aquatic area pollution. An assessment of the impact of wastewater discharged from the Azovstal Iron & Steel Works metallurgical plant on the state of the coastal waters of the Sea of Azov near Mariupol (Ukraine) is presented in the article. The assessment was carried out in accordance with the current Ukrainian legislation and the adopted methodology for water state assessment. The assessment was based on the available monitoring data of sea water in the area of wastewater discharges in the period 2016–2020. The assessment was carried out using the aggregated numerical indices, as well as taking into account the “limiting criterion principle”. Such a methodological approach allowed for a comprehensive assessment of the sea water quality class as well as its sanitary and ecological condition. The results of the assessment allowed us to ascertain the negative impact of industrial wastewater from the metallurgical plant on the coastal zone of the Azov Sea, which made it unsuitable for communal and recreational purposes.

“…In March and June 2016 methods for the operative remote monitoring of the Taganrog Bay and Don estuary aquatic environment state were tested, based on analyzing the shape of the spectra of the spectral brightness of the radiation ascending from the water [22]. Expeditionary materials significantly replenished the oceanographic database of the Southern Scientific Center of the Russian Academy of Sciences [23]: based on field and archival data, the long-term dynamics of organic matter and carbon, transparency and salinity of the Azov Sea [24][25][26] were estimated. The characteristics of small-scale variability of temperature, salinity, internal waves and fluctuations in the level of the Black Sea were calculated [27][28][29].…”

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.
