This paper presents the first study of the so-called ‘brown-clay’ amphorae discovered by the Gonio-Apsaros Polish-Georgian Expedition in the Roman fort of Apsaros (modern Gonio, Georgia) between 2014 and 2018. In the course of five excavation seasons, 157 diagnostic fragments of these containers were attested, all belonging to variants Ch 1B2 and Ch 1C dated to between c. 50 BC and the 3rd century AD. Thus, they confirm the existence of the Apsaros fortress during the first three centuries of the present era. Both Colchian and south-eastern Pontic containers were found in Apsaros, the latter produced probably in Trapezus. This suggests the south-eastern Pontic provenance of some of the imports in Apsaros, especially until the end of the 1st century AD. On the other hand, local production of containers indicates that the area of the fortress might have produced food surpluses (probably wine), which during the late 1st and throughout the 2nd and 3rd centuries AD were exported to other areas neighbouring the Black Sea.

In this research age composition, sex-ratio, growth, survival, mortality and exploitation rates were determined in the south-eastern Black Sea region of Turkey during the 2010–2011 fishing season. Anchovy in the age group 2 was the most abundant (64.06%), followed by age groups 1 (33.12%), 3 (1.80%) and 0 (1.02%). Mean length and weight of the total sample, males and females, were 11.63 ± 0.02 cm, 9.98 ± 0.04 g; 11.39 ± 0.03 cm, 9.40 ± 0.07 g; and 11.98 ± 0.02 cm, 10.73 ± 0.05 g, respectively. The mean condition factor was CF = 0.63 and the sex composition was 61.27% female, 34.40% male and 4.33% unidentified. Equations describing the relationship between length and weight, age and length, and age and weight were derived as W = 0.011 × L2.742, L(t) = 16.368*(1–e−0.425*(t +1.35)) and W(t) = 23.516*(1 –e–0.425*(t+1.35))2,747, respectively. The survival (S), instantaneous total mortality (Z), annual mortality (A), natural mortality (M) and fishing mortality (F) rates were found to be S = 5.8%, Z = 2.84 yr–1,, A = 94.2%, M = 0.66 yr−1, and F = 2.18 yr–1, respectively. The exploitation rate was calculated as 0.77, which is higher than the optimum exploitation level.

The Bronze Age

In most text-books of archaeology the section dealing with the Bronze Age in the Aegean invariably refers us to the culture of Crete and Mycenae. Under the heading of ‘South-Eastern Europe’ we are usually given an account of the Bronze Age of Hungary and the Danubian area. But between these two regions lies an area which is, as yet, almost entirely uncharted by archaeologists, an area which, from its position, is one of the most important in Southern Europe. Between the Danube and the Aegean, the Black Sea and the hills that hem in the river Vardar on its right bank, lies an area across which, by rigidly limited routes, have passed all intrusive elements from Asia and all invading elements into Asia, either by way of the South Russian Steppe or across the Dardanelles and Bosporus.

Rapa Whelk

            The beam trawl fisheries in the Black Sea only target the veined rapa whelk (Rapana venosa) individuals, and other species like fishes and crabs are thrown back into the sea dead or alive. Furthermore, small bivalves and crabs are packed with the target species without any elimination. In this study, a grid-net design (GND) with two different bar spacing was tested to reduce the by-catch. In total 30 hauls (15 hauls for each bar spacing) were carried out in the south-eastern Black Sea between 17 and 26 August 2017. A commercial diamond mesh and one of the grid-net beam trawls were towed simultaneously onboard a commercial vessel to compare the by-catch compositions. Results showed that there were statistically significant (p<0.01) 78% and 83% decreases in the mean weight of the by-catch for 20 and 30 mm grid-nets, respectively. When compared to the conventional gear, a commercial loss of 14% in the 20 mm GND, and 39% in the 30 mm GND in landing values were estimated. In conclusion, use of grid-nets in south-eastern Black Sea beam trawl fisheries can significantly reduce the by-catch of most benthic species. However, it also causes some commercial loss which might be compensated by providing some compensation to fishers such as extension of the fishing season.

High Lead

Lead pollution and its sources have been investigated in the south-eastern and south-western Black Sea. Surficial sediments and mussels were collected in different seasons of the year from the south-eastern and south-western Black Sea and analysed for their lead contents.In the south-eastern Black Sea sediments from the easternmost and from the central stations contained the highest lead concentrations. Sediments contained 8 to 10 times the lead concentrations of sediments from the south-west. Samples taken from rivers, streams and effluents had especially high lead concentrations. The highest lead concentrations were found in sediments collected in October and December.Lead concentrations in mussels from the south-eastern coast were comparatively lower compared to those from the south-western coast. The highest average values occurred in December and in October.In the south-western Black Sea, the highest lead concentrations in sediments were obtained in those from Inebolu, followed by those from around Zonguldak. The concentrations increased from the middle to the west of the southern Black Sea coast, possibly due to the effect of the Danube River. Sediments taken in September had the highest lead concentrations, followed by samples taken in December.Very high lead concentrations (> 10 μ g g-1) were observed in mussels from those stations where the sediments also contained high concentrations. Mussels had their highest lead concentrations in January and April.

In the paper, we discuss a very complex and contestable idea, proposed and developed by us already for several years, about strengthening the uneasy political, economic, social, cultural and most significantly – security relationships between the three South Caucasian countries: Armenia, Azerbaijan, and Georgia, towards forming new geopolitical centre in the south-eastern shore of the Black Sea, or more precisely, just in the middle of the Black and Caspian Seas; in one of the most important and complicated regions in the world. The South Caucasian Union (SCU) concept has quite reasonable historical roots and although not successful enough until now, however certain examples, which could serve as preconditions, whether predispositions more: the existence of the Transcaucasian Democratic Federative Republic (TDFR) (22 April-28 May 1918) and even the Transcaucasian Socialist Federative Soviet Republic (Transcaucasian SFSR or TSFSR) (1922-1936). Along with the corresponding consideration of the region’s hardest internal conflicts, at the same time globally so meaningful, and especially almost the dilemmatic dispute of Armenia and Azerbaijan over Nagorno-Karabakh (NK), but not limited to, we have drawn some feasible conflict-resolution scenarios under the effective SCU model, which ensuring first of all security or in particular, protection of independence and sovereignty of the South Caucasian states as their basic interests, is to logically counterweight any threats coming from bigger, more powerful and ambitious regional competitors, whether dominants and due to evident aggression, from – Russia, in specific.

Hydrate Deposit

Ukraine is an energy-dependent country, with less that 50% of its energy consumption fulfilled by its own resources. Natural gas is of paramount importance, especially for industry and society. Therefore, there is an urgent need to search for alternative and potential energy sources, such as gas hydrate deposits in the Black Sea, which can reduce the consumption of imported gas. It is necessary to refine the process parameters of the dissociation of gas hydrate deposits with a heterogeneous structure. The analyzed known geological–geophysical data devoted to the study of the offshore area and the seabed give grounds to assert the existence of a significant amount of hydrate deposits in the Black Sea. An integrated methodological approach is applied, which consists of the development of algorithms for analytical and laboratory studies of gas volumes obtained during the dissociation of deposits with a heterogeneous structure. These data are used for the computer modelling of the dissociation zone in the Surfer-8.0 software package based on the data interpolation method, which uses three methods for calculating the volumes of modelling bodies. A 3D grid-visualization of the studied part of the gas hydrate deposit has been developed. The dissociation zone parameters of gas hydrate deposits with different shares of rock intercalation, that is, the minimum and maximum diameters, have been determined, and the potentially recoverable gas volumes have been assessed. The effective time of the process of gas hydrate deposit dissociation has been substantiated. The obtained research results of the dissociation process of gas hydrate deposits can be used in the development of new technological schemes for gas recovery from the deep-water Black Sea area.
