In the paper we present the structure of the sections of lithological complexes and their distribution of the at a late stage of the Danish age. We define paleogeographic environment, position of the shoreline and the direction of flows in the flysch through, as well as distribution of island systems and surface elevation. Presented are the climate and the temperature of the marine palaeo-basin.

In the paper, a methodology of the environmental risk assessment of suburban ecosystems of Sochi coastal area from the perspective of the system of environmental indicators is considered. For the purpose of the environmental risk assessment we use materials of study of ranges of natural communities’ digression carried out during the time period from 1991 to 2016. As integral indicators of negative changes in the environment we adopted 23 indicators of human impact, forest taxation, and environmental sustainability. The main method of the research is grouping of variation series of the populations within the five classes. The developed system of integrated environmental risk assessment supplements the basic principles of environmental activities in the ecosystems of the Sochi coast, aimed at their multipurpose recreational and tourist use, promotion and preservation of their protective functions. The system can be applied for the improvement of risk management and to minimize possible environmental losses.

Authors: Based on the observations of fog at the Tbilisi airport, the authors calculated the probability of formation of fog and its average duration. On the basis of these data, there was developed a classification of complexity categories of the weather. Based on observational data, the authors calculated the probability of fog, its average duration, and, according to the developed classification, the category of difficulty the weather.
