The aim of our investigation is a survey of heavy metal pollution in algae, sediments and water from the Bulgarian Black Sea coast and determination of algae species appropriate as bioindicators. The levels of iron, copper, manganese, zinc, lead and cadmium are determined in water, sediments and eight species of macroalgae: (four green: Cladofora laetevirens, Ulva rigida, Enteromorpha intestinalis and Bryopsis plumosa; two brown: Cystoseira crinita and Cystoseira barbata; and two red: Ceramium rubrum and Corallina mediterranium), widely distributed in the Bulgarian coastal zone, and dominant in the Black Sea. The studied area is the littoral coastal zone from four locations - Tuzlata, Ravda, Ahtopol and Sinemoretz. No significant variations between metal concentrations in algae samples are obtained, while for sediments and water there are significant differences between location and season. The Cladofora laetevirens and Ceramium rubrum species show the highest metal content while Cystoseira crinita and Cystoseira barbata show the lowest level. The correlation coefficients and concentration factors of the elements are calculated.

<p>Over the last two decades, in line with the global trend of expanding research into natural hazards and disaster risk reduction, the tsunami hazard and risk assessment along the coast of Europe has become a hot topic of research. In all its aspects, tsunami research includes the study of tsunami documentary evidence, historical data collection, field experiments, laboratory research, theoretical numerical and analytical modelling, and in-depth analysis of recent tsunami events. Tsunami modelling research methodologies and holistic approaches to risk assessment are continually being improved. Researches are directed to develop conventional standardised methods to analyse tsunami hazard and risk with associated uncertainties, aiming to reduce possible adverse effects on potentially vulnerable coastal settlements, coastal and marine infrastructures and natural ecosystems.</p><p>In the Black Sea, dangerous tsunami waves are a relatively rare phenomenon that cannot be forecast. Multidisciplinary studies focused on mapping and dating past events on the Black Sea coast, determining the causes, frequency of recurrence, and current prospects for tsunamis occurrence (risk) are not yet fully clarified or are in their infancy. Moreover, tsunami hazard along the Bulgarian coast is poorly understood and not considered in the National methodology for flood hazards and risk in the coastal zone. Numerical tsunami modelling performed in recent years for the region still needs to be improved. These events are relatively rare, few such cases have been documented, and validation data are scarce or missing.</p><p>This study provides a comprehensive inventory of tsunami sources from scientific publications, model studies of tsunami generated waves carried out during the recent years and an analysis of the results from recently established early warning systems in the Black Sea region. For the Bulgarian coastal zone, the results of studies of active faults with tsunamigenic potential in and around vulnerable coastal zones, available registrations at sea level during seismic events and some extreme meteorological events for the last century are summarized. A near-field and far-field tsunami sources that can generate tsunamis and affect the Bulgarian coastline are briefly reviewed. High-resolution data are needed for more credible tsunami numerical modelling for the western Black Sea region. Preliminary studies of the available datasets regarding Digital Elevation Model (DEM) and bathymetry for specific locations along the coastal zone are presented as well the needed accuracy and completeness of the data. Some consideration regarding the available and newly establish research infrastructure in the western Black Sea are also discussed.</p><p><strong>Acknowledgements:</strong><strong> </strong>The authors would like to thank the Bulgarian National Science Fund for co-funding the research under the Contract КП-СЕ-КОСТ/8, 25.09.2020, which is carried out within the framework of COST Action 18109 “Accelerating Global science In Tsunami HAzard and Risk analysis” (AGITHAR; https://www.agithar.uni-hamburg.de/).</p>

Tourist Flow

Among all the natural resources available in Odesa Region vacationists prefer beaches and associated entertainments. Quality and general ecological condition of the beaches in addition to the potential and actual beach capacity are key factors for tourist flow to Odesa Region and its socio-economic development. In order to substantiate the recreational and tourist development of the territory an economic and logistic evaluation of its resource base should be carried out. This will make it possible to determine an input tourist flow which dictates the volumes of required tourist infrastructure and material and technical facilities. The purpose of this study is to evaluate recreational potential of Odesa Region’s beach zones. To achieve this, all main natural and anthropogenic factors determining the recreational potential of the coastal zone were analyzed. The study is also based on scientific researches in the field of recreational and tourist activities made by well-known experts, on the existing regulatory frameworks and results of the authors' own research works. For the first time, recreational capacity and logistic potential of Odesa Region’s beach zones were estimated. Based on this estimation multiple conclusions about the most promising areas for future development of the recreation sector were made. It was determined that favorable climatic conditions, considerable length of beaches and other natural and recreational resources allow us to speak about good prospects of the Odesa Region’s coastal zone for various forms of recreation including thalassotherapy. In fact, thalassotherapy opportunity (first of all, beach recreation) is a very important factor of attractiveness for vacationists visiting the Odesa Region’s coastal zone. According to our research, Bilhorod-Dnistrovskyi, Tatarbunarskyi and Lymanskyi districts are the most promising ones for recreational development. The total capacity of the beaches here even exceeds the districts' own population. Conducted recreational zoning of the Odesa’s Black Sea coast established that, based on the natural recreational factors, out of 9 recreational microdistricts only 3 of them may be classified as favorable, with 5 being relatively favorable and 1 – completely unfavorable. But, from the perspective of sea water quality, some microdistricts (Luzanivskyi and Arkadiyskyi) do not meet sanitary standards during the period of intense precipitation. It was found that there is a need for expansion of beach areas as well as a need for regulation and redistribution of the recreational and tourist flow. In order to increase recreational attractiveness of Odesa Region, regional and city administrations should pay more attention to the ecological conditions of beach areas of the Black Sea coast. The obtained results may be used by the Department of Culture and Tourism of the Odesa Regional State Administration, divisions of the Ministry of Ecology and Natural Resources of Ukraine in order to assess the recreational potential of the Odesa Region’s beach areas.

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.

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.

The Black Sea, surrounded by six riparian countries, is under the threat of severe pollution, giving rise to the need of taking precautions to protect it from further deterioration. In this paper, an effort putting forth a wastewater treatment and management strategy is outlined for the Black Sea coast of Turkey, including both the technical and financial aspects. The present situation of the coast in terms of land-based pollution and infrastructure is stated, followed by an applicable management strategy. The strategy developed for the coastal settlements involves various stagewise treatment schemes based on population distribution and densities along the coastline, and on the availability of land in a specified period of thirty years. Similar strategies are proposed for the control of pollution originating from industries, for those carried by rivers joining the sea, and for leachate of solid waste landfills. The cost estimations of various treatment schemes are also given in terms of population equivalents.
