Oil Hydrocarbons

Aim. Currently, oil pollution remains one of the primary pollutants of the marine environment. This is especially true for the Black Sea and Azov Sea which experience significant anthropogenic pressure. The study presents the results of two-year monitoring studies of the content of oil hydrocarbons in the surface and bottom horizons of the coastal waters of the Azov-Black Sea regions of Russia.Materials and Methods. The determination of oil hydrocarbons was conducted by infrared spectrometry using a FSM-1201 Fourier spectrophotometer with preliminary transmission of the extracts through a chromatographic column with aluminum oxide. The work was carried out as part of five scientific expeditions (93th, 96th, 100th, 102nd and 105th) of the research vessel, Professor Vodyanitsky, in 2017 and 2018.Results. The general environmental status for this pollutant is characterized as stable, despite in some cases being 3 to 4 times in excess of established standards (MPC). Separate foci of localized oil pollution have been identified and vulnerable areas of the sea coast of southern Russia have been identified. An excess content of petroleum hydrocarbons in the surface layer compared to the bottom layer was noted, which indicates a surface path of entry of petroleum products into sea water.Conclusion. Currently, the coastal waters of the western part of Crimea are most affected by oil, primarily associated with the runoff of European rivers and the peculiarities of the marine hydrological regime, including the Kerch Strait, an area of heavy shipping traffic. The Caucasian coast is less affected by oil pollution than the Crimean. Despite the fact that currently the content of oil hydrocarbons in sea water is far from the quantities dangerous to humans and aquatic organisms, monitoring of this indicator is vital due to the increasing anthropogenic pressure on the recreational zones of the Crimean and Caucasian coasts of the Russian Federation.

Long-term (20032014) routine observations of zooplankton in Sevastopol Bay (the Black Sea) have allowed the naturalization of the invasive copepod Oithona davisae to be studied in the Black Sea coastal waters. Inter-annual and seasonal variability of the species and their impact on the native copepod community have been analyzed. The invasion of O. davisae and their undoubted dominance in terms of abundance were shown to alter the community structure but, at the same time, the abundances of the native species did not decrease, excepting the Black Sea earlier invader Acartia tonsa. A significant decline in A. tonsa numbers over the stages of O. davisae establishment and naturalization provided evidence of competition between the species. O. davisae have been demonstrated to gain competitive advantage over A. tonsa, that ensured their fast dispersal in the Black Sea, acclimatization in the new habitat and the successful competition over native species.

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.

In August 2015 we managed to capture a specimen of ratan goby (Ponticola ratan) in the Romanian coastal waters of the Black Sea, near the locality of Sf. Gheorghe (Tulcea County). This is the 7-th signaling for this species in Romanian coastal waters. The previous 6 specimens were recorded in the period 1960-1993, between Mangalia (Constanţa County) and Sulina (Tulcea County). The species was identified by means of meristic characters (number of scales on medial line, number of spiny and soft rays), and morphological particularities (cycloid scales on the nape area and pectoral fin joint). Also, the measurements made, confirmed that the ratio between the head length and total length, which was 33% (TL=8.70 cm vs. Head Length=2.61cm). Another morphological character, specific to this species, is the lower jaw, which exceeds in length the upper jaw. Being a Ponto-Caspian endemite, with low population along the Bulgarian and Romanian coastline, we considered it important to point out this new record. Noting that, being known the trend of sporadic migration of this species, would not be excluded that global warming causes a shift from its normal distribution area, from northern and northeastern (Black Sea) to south-west. Therefore, future research may bring more notifications regarding this species in south-western area of the Black Sea

The paper notes that the hydrocarbon potential of the Black Sea-Caspian region is not exhausted, and therefore the development of its resources is intensifying. The exploitation of oil and gas fields is closely associated with negative consequences for theenvironment. Therefore, the geo-environmental features of the area must be studied and taken into consideration. In relation to the Black Sea-Caspian region the authors have identified and described such features as: the diversity of geopolitical, regional-geological, geographical conditions; the factor of stability of the geological environment; oil pollution of the marine environment and the organization of monitoring of oil pollution.
