Scholarly Attention

The article examines the problems in developing approaches for the description and stylistic interpretation of antique masonry, as well as the issues in their stylistic dating. The task of dating construction remains belonging to the 7th century B.C.E. to the turn of the era, has attracted the scholarly attention of the scientific community since the 1940s and has been considered by both foreign and Russian researchers. The article's research object is the construction remains of Greek civil and military architecture in the Mediterranean and the Northern Black Sea regions - territories considered to have been the center and periphery of the Greek Oikumena. The study applied the comparative-typological method, the synchronization of objects in time and space, and dating by analogy. Both in Russian and foreign studies a significant amount of data has been collected for the analysis and construction of appropriate conclusions regarding the distribution and popularity of certain masonry in particular periods of time. However, due to the presence of many factors affecting the ancient construction and stone-carving craft, a number of exceptions due to local natural, economic, raw material, and administrative factors can be distinguished in the observed patterns. Thus, the whole picture of the formation of the construction and stone-carving craft (with the allocation of the corresponding types of masonry in a certain historical period) can be reconstructed only with a comprehensive examination of all of them. As the most interesting objects in this regard, the article cites a number of architectural remains belonging to the monuments of the distant chora of Tauric Chersonesos dating to the second half of the 4th century B.C.E.

Results of multiyear monitoring of zones of persistent ecological risk in the Black Sea are presented. These ones are most affected by oil pollution, raised concentration of suspended particulate matter and harmful algae bloom. Studies are based on satellite remote sensing data obtained over the Black Sea from 2000 to 2017 from radar sensors ERS-2 SAR, Envisat ASAR, Sentinel -1A, -B, Radarsat 2, TerraSAR-X; visible and infrared data from Envisat  MERIS, Landsat-5 TM, Landsat-7 ETM+, Landsat-8 OLI,  MSI Sentinel-2A and Terra/Aqua Modis. An analysis of radar data indicated areas most affected by ship spills of bilge waters. Greatest polluted area were found along the main ship routes, near biggest ports and at sites of anchor positions.It is necessary to separate anthropogenic oil pollution and oil-containing slicks caused by natural hydrocarbon seeps including mud volcanoes, natural gas and oil outflows from the sea bottom, and gas hydrates. The geographical distribution of these slicks is defined by their permanent locations that well correlate with locations of natural hydrocarbon seeps from the sea bottom in this region.Areas characterized by increased concentration of suspended particulate matter were revealed at maps compiled from Envisat MERIS, MSI Sentinel-2A data and Landsat colour composites. Among the most notable ones are river plume zones, first of all, those of the Danube River and mountain rivers of Georgia. Results of satellite data processing were used for detecting impacts of various natural factors, such as precipitation, rivers flows, wind-driven water circulation and vortex activity, on suspended matter proliferation. Mapping of zones of maximum propagation of suspended solids in different seasons was performed for the examined areas. Eutrophication has recently become a very important problem worldwide. It is true also for the Black Sea, especially for its western part.
