“…Geographical location of the Sevastopol Bay; scheme of the oceanological stations, location of the sewage releases [7] and the local maximums of the dissolved oil products' concentrations Along with the concentration field of oil products dissolved in water, the TSM and DOM content fields are considered in the interpretation of the results. These substances content was determined on the basis of optical methods [8,9] implemented in the Kondor optical biophysical probing complex (hydrobiophysical multiparameter immersion autonomous complex, URL: http://ecodevice.com.ru/ecodevice-catalogue/multiturbidimeter-kondor). By means of this device, arrays of synchronous measurements (in situ) of TSM and DOM contents in a sounding mode with a resolution of 0.1 m in depth were accumulated and analyzed.…”

The aim of the work is to identify the patterns of the dissolved oil (DO) field structure in the Sevastopol Bay waters and the factors conditioning its state, to compare the obtained result with the available ideas on large-scale distribution of the water quality indicators on the area under study, to evaluate the current trend of the dissolved oil field state, to consider the relationship between the fields of the dissolved oil concentration, the total suspended matter (TSM) and the dissolved organic matter (DOM). Methods and Results. Based on the data of a series of the oceanological expeditions carried out by Marine Hydrophysical Institute and Institute of Natural and Technical Systems in 1999-2018, the structure of the dissolved oil content field in the Sevastopol Bay (the Black Sea) and the forming it factors are considered. The obtained result is compared with the known structural regularities of the hydrochemical elements' fields. A tendency of the state of the dissolved oil concentration field is assessed. The relationship between the fields of the dissolved oil concentration, total suspended matter and the dissolved organic matter is considered. Conclusions. It is shown that the structure of the dissolved oil content field is conditioned by interaction of the polluted waters in the Sevastopol Bay apex (spacious maximum of the substance concentration was revealed in the region of the Neftyanaya Harbor) with the pure Black Sea waters in its western region. The characteristic structural element of the field under investigation is a wellpronounced meridian frontal section observed on the Southern Bay traverse. Significant local maximum values in the dissolved oil field were observed also in the bays Kilen, Korabel'naya, Artilleriyskaya and Severnaya. The frontal section in the dissolved oil concentration field coincided with the boundary section in the hydrochemical elements' fields, which was earlier revealed in course of studying water pollution in the Sevastopol Bay. Noted are the tendency to decrease of the dissolved oil products' concentration in the Southern Bay waters and the qualitative difference of this substance structure being compared to the fields of the total suspended matter and the dissolved organic matter concentrations.

In the present paper structural regularities of the total suspended matter (TSM) and dissolved organic matter (DOM) content fields and the dissolved oil products (OP) concentration in the dredging and dumping areas in the Kerch Strait and the adjacent regions are identified based on the oceanographic data of the expeditions of the Marine Hydrophysical Institute and the Southern Research Institute of Marine Fishery and Oceanography Data and methods. The data of nine complex expeditions in the Kerch Strait in 1999-2013 were analyzed. The concentrations of all the substances under study were determined applying the optical methods. All the surveys were carried out in a probing mode using the Kondor optical probe. Results. It is shown that sea dredging in the commercial port of Kerch was accompanied by significant increase of the total suspended matter content; its concentration was dozen times higher than that in the adjacent area. High content of the total suspended matter, characteristic for the port and the surrounding waters, contributes to accumulation and deposition of the anthropogenic dissolved organic matter, which concentration significantly exceeds the natural one. It is revealed that the dumping zones remain the sources of seawater environment pollution. The pronounced local maxima of the total suspended matter, dissolved organic matter and dissolved oil products concentrations were revealed in the bottom layer just in these zones: here they 1.5-3 times exceeded the natural standards of the considered characteristics. Discussion and conclusion. Dredging is the most significant factor determining the high concentration of suspended matter of anthropogenic origin in the Kerch Strait. The soil removed during dredging has an extremely low compaction and abnormally high fluidity that promotes intensive erosion of the dumping zones and further spread of suspension in the ambient waters. Dredging and dumping zones are not only pockets of environmental hazards; they are also unfavorable for navigation.

При помощи этого прибора были накоплены и проанализированы массивы синхронных измерений in situ содержания ОВВ и РОВ в зондирующем режиме с дискретностью по глубине 0,1 м. Отметим, что РОВ, характеризующее антропогенное, в том числе и бактериальное загрязнение, относят к одному из лучших показателей качества вод прибрежных морских и океанских акваторий [8,9].…”
