The article presents measurement results and examples of spatial distributions of flow velocities required for solving various problems related to mass transfer, coast erosion and silting of water areas. Analysis of expedition research results obtained using the developed complex allowed to create methodical approaches to assess the current state of a water body and informative parameters of its state using a visualization method. Based on the created methods, data on the fine structure of the flow in the Chernaya River estuary area were obtained. Comparison of the averaged data on the water flow velocity with the measurement results obtained through standard technical means, namely a hydrometric current meter, showed minimal discrepancies not exceeding 11 %. The developed method and technical means make it possible to study the water flow dynamics and to describe the flow fine structure, which is necessary for studying the mechanisms of erosion, sediment accumulation and transport.","PeriodicalId":332238,"journal":{"name":"Ekologicheskaya bezopasnost' pribrezhnoy i shel'fovoy zon morya","volume":"29 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122554585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a high spatial resolution (horizontal grid ~1.6 × 1.6 km and 27 vertical layers) model and realistic atmospheric forcing. The assimilation procedure of observational data was based on a modified Kalman filter taking into account the heterogeneity and anisotropy of estimation error of the temperature and salinity fields. The calculated fields of currents were characterized by eddies and jet currents. The following circulation features were observed in the northern part of the Black Sea: an intense jet of the Black Sea Rim Current along the Crimean coast, anticyclonic eddies with a radius of about 30 km near Sevastopol and in the western part of the region, a cyclonic eddy with a radius of about 40 km between 34.5 and 35.5 E, anticyclonic eddies with a radius of about 25 km along the Crimean coast. Eddy formations of different scales and different signs of rotation were obtained (in the Kalamitsky Bay, in the eastern part and along the eastern coast of the Crimea), when the current flowed around irregularities of the coastline and the bottom relief in the coastal zone. The correlation between the formation of zones of lower and higher temperature relative to adjacent waters and the location of features in the field of current (in particular, the correspondence of zones with warmer desalinated water to the anticyclonic formations) was noted from the analysis of the reconstructed thermohaline fields.","PeriodicalId":332238,"journal":{"name":"Ekologicheskaya bezopasnost' pribrezhnoy i shel'fovoy zon morya","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117212946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the materials of observations in 2020, the paper characterizes the content of mineral nitrogen compounds (in the form of nitrites, nitrates, ammonium, and total content) and mineral phosphorus in the estuarine area of the Vodopadnaya River, which flows into the Black Sea within the city of Yalta. The influence of atmospheric precipitation on the change in the concentrations of nutrients in the waters of the mouth reach and estuarine front was determined. It was established that nutrient input with the river runoff can shift the nitrogen limitation of the phytoplankton primary production to the phosphorus one. It was shown that river runoff is one of the key factors affecting the degree of eutrophication of sea waters within the recreational zone of Yalta.

It is established that the bottom sediments in the wastewater discharge area of “Yuzhnye” Integrated Sewage Treatment Plant are represented by rudaceous and coarsegrained fractions. These are mineral particles formed both as a result of coastal abrasion and in the process of accumulation and diagenesis (shell rock, detrital sand) of bottom sediments.

These were mostly unconsolidated water-saturated sediments with low carbonate content, high organic carbon and moisture content and signs (impurities, consistency, odour) characteristic of municipal sewage sludge. It is noted that the accumulation level of anthropogenic organic carbon is comparable to that of organic matter in the bottom sediments of Sevastopol region bays characterized by limited water exchange and subject to long-term anthropogenic pollution.

Recent field data are compared with the literature data obtained in the period before the commissioning of the North Crimean Canal. Salinity in water samples taken during 18 expeditions to the Eastern and Southern Sivash at over 100 stations was determined using the refractometric method. It was shown that after the closure of the North Crimean Canal in 2014, there was a steep increase in salinity in the Eastern and Southern Sivash. It was determined that in the area of the Sivash Bay, the haline field changes non-uniformly. The data analysis showed that salinity increases from north to south (from the Eastern to Southern Sivash), moreover salinity values in the Southern Sivash can be several times higher than those in the Eastern Sivash. In spring 2014, salinity in the Eastern Sivash varied from 27 to 33 ‰, and in 2020, 6 years after the closure of the Canal, salinity increased significantly at all stations reaching 60–70 ‰. These values are comparable to those obtained before the start of the Canal in the 1950s. The highest salinity values were observed in the South Sivash: in 2013, it was 54 ‰ and in summer 2020, for the first time since the North Crimean Canal became operational, it reached 110 ‰, which almost corresponds to the salinity level observed in 1969.","PeriodicalId":332238,"journal":{"name":"Ekologicheskaya bezopasnost' pribrezhnoy i shel'fovoy zon morya","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both in 2020 and 2016 (the 83d cruise of the R/V “Professor Vodyanitsky”), properties of the bottom sediments of the Crimean and Caucasian coasts were typical of the marine soils of this region. This indicates that the studied water areas are generally in good condition. In accordance with the regional classification of bottom sediment pollution, the maximum concentrations of chloroform-extractable substances obtained for both the Black Sea and the Sea of Azov coast indicate pollution level III (23% of analysed samples). These values were found in bottom sediments in the Sevastopol water area (225 mg·100 g-1), in the coastal area of Cape Tarkhankut (120 mg·100 g-1) and Karadag (120 mg·100 g-1), the southern part of the Sea of Azov (125 mg·100 g-1) and Tuapse (110 mg·100 g-1). The content of chloroform-extractable substances in bottom sediments off the Black Sea coast of the Caucasus and the Sea of Azov coast is slightly lower than that off the Crimean coast.

The paper aims at a comprehensive study of regional characteristics of wind waves near the village of Morskoye (south-eastern coast of Crimea), which are necessary to develop a project of reconstruction of the highway adjacent to the coastal area. Space images and cartographic information were used to study the beach dynamics in the studied area. It is shown that before construction of the coast protection structures the beach width in the studied area was 25–30 m, whereas after the construction it narrowed down to 15–25 m. Based on the wind wave reanalysis data obtained using SWAN spectral model and ERA-Interim surface wind fields for 1979–2017, regime characteristics of waves in the coastal zone of Morskoye were calculated. It was found that waves with average periods of 3.0–3.5 s have the maximum recurrence (over 16 %). Wind waves coming from SE-SSE sector have the highest recurrence rate. Estimates were obtained for the extreme characteristics of wind waves that may occur once in a given number of years. The SWASH hydrodynamic model was used to perform mathematical modelling of wave run-up on the coastal area. In their calculations the authors used a regular grid of the coastal relief with high spatial resolution based on the interpolation of topo-geodetic and bathymetric survey results. An incoming wave was given as a soliton of 2.0; 3.0 and 3.4 m high. It was found that with the incoming wave height of 2.0 m, the vertical wave splash in the studied area varies within 1.7–2.2 m. At a height of 3.4 m, the splash reaches 1.8–2.9 m. In this case the beach is flooded completely. During the run-up, wave current velocity amounts up to 5 m/s. Along the lower boundary of the cliff the bottom maximum current velocity reaches 1.5–1.75 m/s. At such velocities near the cliff, the beach consisting of material with the grain size up to 60–90 mm can be eroded.","PeriodicalId":332238,"journal":{"name":"Ekologicheskaya bezopasnost' pribrezhnoy i shel'fovoy zon morya","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125424007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
