Holocene fluctuations of the Black Sea level have played a significant role in the existence of the Black Sea polis-cities. The high sea-level during the Novochernomorian transgression is followed by the Phanagorian regression when the sea level reached its minimum of 3 m below the modern sea level during the antiquity (Roman Age). Then, on the west coast of Mandra Lake the Roman polis Deultum was founded which became a flourishing port. The discrepancy between the low sea level and ancient navigation activity in Mandra Lake is a challenge for further investigations of the Holocene sediments.

Abstract Firths are geomoiphological and hydrological sites typical for flat, neutral coast of no tidal sea basins. There in the greatest extend is preserved the geological column of the correlative Pleistocene- Holocene sediments. They make possible to reveal the Quaternary evolution of the contact zone „land-sea“. Firths are one of the most reliable indicators for the Quaternary Earth crust movements. Along the Black Sea coast most widely are developed the firths in the north - west and the west periphery, where they form a classic firth type coast. This report examines the results of complex studies of Batova river firth, located (developed) on the North Bulgarian Black Sea coast.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.

In the second half of the Ist century BC seismogenic landslide/rockfall tore off the front part of the Chirakman Cape in the western part of the Kavarna Bay. The rich quarters of the Roman city of Bisone slid down into the sea. According to data from underwater archaeology artifacts and walls of the settlement are found up to 80 m inside the sea. The paper considers the tectonic conditions, the geological-geomorphological structure of the landslide, the paleogeography of the coastal shelf during the Holocene and the hydrogeological and engineering geological conditions in the area. A reconstruction of the coastline and sea-level position during the catastrophic landslide has been developed. Stability analyses have been performed too.

In this study, we focus on sea level changes along the Black Sea coast. For this purpose, at same observation period the linear trends and the components of seasonal variations of sea level change are estimated at 12 tide gauge sites (Amasra, Igneada, Trabzon-II, Sinop, Sile, Poti, Batumi, Sevastopol, Tuapse, Varna, Bourgas, and Constantza) located along the Black Sea coast and available altimetric grid points closest to the tide gauge locations. The consistency of the results derived from both observations are investigated and interpreted. Furthermore, in order to compare the trends at the same location, it is interpolated from the trends obtained at the altimetric grid points in the defined neighbouring area with a diameter of 0.125° using a weighted average interpolation algorithm at each tide gauge site. For some tide gauges such as Sevastopol, Varna, and Bourgas, it is very likely that the trend estimates are not reliable because the time-spans overlapping the altimeter period are too short. At Sile, the long-term change for the time series of both data types do not give statistically significant linear rates. However, when the sites have long-term records, a general agreement between the satellite altimetry and tide gauge time series is observed at Poti (~20 years) and Tuapse (~18 years). On the other hand, the difference of annual phase between satellite altimetry and tide gauge results is from 1.32° to 71.48°.

The Crimean Peninsula

The expansion of Oenanthe isabellina in Ukraine began at the end of 1950s - early 1960s. The Isabelline Wheatear settled along the coast of the Sea of Azov from east to west and appeared on the Crimean Peninsula later than in the regions located to the west of it. Since the late 1960s, this species has been nesting near the mouth of the Dnipro River which located in the west of the Crimean Peninsula. The nesting of Oenanthe isabellina was found in the northern part of the Crimean Peninsula in 1973. In the mid-1980s, the Isabelline Wheatear inhabited the northwestern coast of Crimea and appeared far in the east - on the Kerch Peninsula. In the southeastern part of the peninsula the range of the Wheatear reached the Black Sea coast by the end of the 1980s, when the species nesting was found near Feodosia. In the southeastern part of Crimea, the Isabelline Wheatear continued to settle along the Black Sea coast in a westerly direction in the 1990s: its nesting was found near Sudak. In the central Crimea, the species range reached the northern foothills of the Crimean Mountains at this time. The species expansion to the south slowed down by the beginning of the 2000s. In the western Crimea, the southernmost settlement of the Isabelline Wheatear was found near Evpatoria. In the northern foothills of the Crimean Mountains (Central Crimea), the range border has not changed. There were no significant changes in the southeastern Crimea during this period - in the 2000s, O. isabellina nested near Sudak as in the 1990s. The species expansion almost stopped in Crimea in the 2010s. The settling of the Isabelline Wheatear in the steppe regions of the southwestern Crimea did not occur, possibly due to the absence of little ground squirrel settlements, whose burrows birds usually use for nesting. The border of the O. isabellina range has moved southward on about 100 km for three decades - from the beginning of the 1970s to the beginning of the 2000s -, i.e. the settlement speed of the species in Crimea was about 3 km per year.

Mithridates II was succeeded by his ephemeral son, Mithridates III, and then by 220 BC his son, Pharnakes I, was on the throne. He was a powerful and aggressive monarch who ruled for over thirty years and greatly expanded the territorial extent of the kingdom. He lived in an era of great change in the Hellenistic world, as the Romans began to become involved in the destinies of the eastern Mediterranean states: Pharnakes reached out to the Romans in the 180s BC concerning territorial disputes in Asia Minor. He engaged in war with his powerful neighbor to the west, Pergamon, but was forced to sign a peace treaty not to his advantage. Yet he expanded Pontic territory along the Black Sea coast and made several alliances with the Greek cities on the northern and western coast of the sea, especially in the kingdom of Bosporos (modern Crimea).

Typical coastal elements of limans and lagoons are barriers, that separate limanic aquatories from a Seas. On limanic shores structure of the Black Sea sand barriers represented three longitudinal landscape “zones”: sea beach (“frontal”), dune-aeolian and limanic (“back of the barrier”). They closely interactive between themselves under influence of lithodynamical exchanges of sediment. General tendency of the barriers dynamics is displacement to Land direction.
