The Anapa bay-bar is located in the northwestern part of the Black Sea. With the goal in mind to determine the short-term dynamics of the Anapa bay-bar we analyzed satellite images from 2003 to the present. Depending on the hydro-lithodynamical situation the shoreline configuration during storm can vary from a rectilinear to sinusoidal forms. There are regions of local erosion or accumulation whose formation is related to the alongshore motion of sediments and dynamics of underwater bars. Comparison of the data on 1965 and 1966 showed that in this period the amplitude of the shoreline position was more than 20 m but average displacement of the shoreline for 13 months was only 0.8 m. This study showed that for the analysis of changes in the shoreline position is necessary to consider the configuration of the coastline at the time of each observation and the local dynamics.

Russian fishermen harvest European anchovy primarily off the Black Sea coast of the Krasnodar Territory during its wintering and wintering migrations. At wintering grounds, temperature conditions become a secondary factor in determining the behaviour of commercial concentration of European anchovy, with wind and currents being the primary factors. Therefore, the aim of this work is to determine the potential use of daily data on water circulation and local atmospheric transport in short-term (1–7 days) forecasting of European anchovy fishing in the Black Sea. The research used the European anchovy fishery monitoring materials for January – March 2019, as well as daily maps of the Black and Azov Seas level anomalies (from satellite altimetry data) and surface atmospheric pressure and temperature in Europe (analysis) for the mentioned period. The dynamics of the catch rate and its relation to altimetry and atmospheric transport indicators in the north-eastern part of the Black Sea were investigated using graphical and correlation methods. This analysis showed that the main factor contributing to increased catches is intensification of northwest currents in the coastal 60-km zone. The effect of atmospheric transport on fishing efficiency depends on the mesoscale eddy structure of the nearshore current field. In the presence of an intense northwest current in the fishing area, southwest atmospheric transports have a positive effect on fishing, while in the presence of an anticyclonic meander of currents, northeast atmospheric transports become effective. The presence of maximum significant relationships when the determinants of fishing performance are shifted by 1–7 days allows making short-term predictions of fishing efficiency.

During 2015–2106 the macrozoobenthos under the clam farm located in the area of Sevastopol was investigated. The aim of the study is to consider species composition, density and biomass of macrozoobenthos in the area of the clam farm. The samples were taken using standard benthic techniques. Relatively low species diversity was observed, with 56 species of macrozoobenthos identified. The density was 500–975 ind. per m², the biomass varied from 0.8 to 381.1 g·m-2. The community of the bivalve mollusk Lucinella divaricata (Linnaeus, 1758) was found. Trophic structure of the community with high quantity of detritus feeders dominated by small polychaetes was determined. The dominating, typical and rare species were identified. Comparison with the data obtained in 1957 in Evpatoriya – Sevastopol area at the same depths and sediments was made.

In the year 8 CE, Ovid was exiled to the Black Sea for “a song and a mistake.” This chapter explores a series of iconic poems from the Tristia in which Ovid imagines the state of exile through a variety of textual media: his own books of poetry sent back to the city and rejected from the public libraries; the lapidary inscriptions of Augustus he imagines them to encounter; and, several times over, his own funerary epitaph, formulated in explicit competition with Augustus’s own monumental list of deeds, the Res gestae. It is an examination of the challenges presented to the poet by exile and how he uses writing itself and written forms, real and imagined, to overcome that distance and disgrace, becoming increasingly aware that it was at the level of written language, and only at that level, that he and the emperor were “on the same page.”

The Black Sea subspecies of the bottlenose dolphin (Tursiops truncatus ponticus) is threatened and has a small range. Its population structure is little known: it possibly includes a few local coastal populations. We assessed connectivity between coastal groupings in six localities along 800 km of the coastline based on records of photo-identified animals between 2004 and 2014. Abundance of these groupings, as estimated, ranged between 76 and 174 individually distinctive dolphins. In total, there were 350 identified individuals, of which 91 (26%) were resighted within the same areas. However, only three cases of individual movements between local coastal populations were recorded at the distances between 135 and 325 km. Therefore, despite the absence of physical barriers, the coastal Black Sea population is fragmented into numerous resident or locally migrating groupings with site fidelity. These local populations are loosely connected to each other with rare movements between them. This fragmentation can be a factor contributing to short-term fluctuations in abundance of Black Sea bottlenose dolphins and their decline in some localities, despite the potentially high population growth rate.

Abstract Terenko L., Terenko G., 2012: Dominant Pseudo-nitzschia (Bacillariophyta) species in the Black Sea (Ukraine) [Vyraujančios Pseudo-nitzschia (Bacillariophyta) rūšys Juodojoje jūroje (Ukraina)]. - Bot. Lith., 18(1): 27-34. Diatoms of the genus Pseudo-nitzschia (order Pennales) are persistent component of the phytoplankton community in the Black Sea and may reach bloom level during some periods in summer and autumn. Six potentially toxic and non-toxic Pseudo-nitzschia species were recorded up to date in the Ukrainian waters. Since 1980s, several mass developments of Pseudo-nitzschia spp. have been observed. Morphological analysis revealed Pseudo-nitzschia delicatissima, P. pseudodelicatissima, P. pungens, P. seriata as the dominant species in the blooms. Pronounced bloom of Pseudo-nitzschia spp. reaching up to 80 % of total phytoplankton abundance and occupying wide area of the Black Sea was observed in June 2001. The summer density peak of P. delicatissima and P. seriata was observed at 16.0-17.5 °С and salinity 15.2-15.7 ‰ in the coastal waters of Odessa Bay. In December 2005, the density of Pseudo-nitzschia spp. in the bottom layers in Odessa region reached 3.0·106 cells l-1. In June 2008, a single species P. pseudodelicatissima bloomed in the Danube region. The density of the species came up to 12.0·106 cells l-1. At the end of May 2009, P. delicatissima showed short-term and lower magnitude density peak (3.1·106 cells l-1) in the coastal zone of Odessa Bay. Thus, the Pseudo-nitzschia spp. blooms are frequent phenomena in the Black Sea and may occur in any season of a year. These species are indicators of trophic state in marine waters.
