This study investigates fatalities due to rip currents on the Black Sea coast of Istanbul. Results include the incidence rate of fatalities from rip currents, their causes, temporal and spatial distributions. The data shows that, nearly 70% of all drowning fatalities are associated with rip currents, and that on the average 33 people reportedly die from rip currents each year in Istanbul Black Sea coast. Thus, considering the wind speeds versus rip current fatalities, about one third of the fatalities occur when the wind speed is between 1.5-2.0 m/s. For the wind speeds 1.0-1.5 m/s the rip current magnitude is not too intense so people consider themselves capable enough to swim but for poor swimmers this is the most dangerous case. Nearly 60% of the fatalities in this wind speed interval is found to be children.

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.

Tourism is one of the most dynamically developing branches of economy in the Russian Federation in general and on the Black Sea coast in particular, in this regard, the assessment of tourism potential is one of the most important tasks of regional management.

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.

Abstract. Continuous wind profile and turbulence measurements were initiated in July 2008 at the coastal meteorological observatory of Ahtopol on the Black Sea (south-east Bulgaria) under a Bulgarian-Russian collaborative program. These observations are the start of high resolution atmospheric boundary layer vertical structure climatology at the Bulgarian Black Sea coast using remote sensing technology and turbulence measurements. The potential of the measurement program with respect to this goal is illustrated with examples of sea breeze formation and characteristics during the summer of 2008. The analysis revealed three distinct types of weather conditions: no breeze, breeze with sharp frontal passage and gradually developing breeze. During the sea breeze days, the average wind speed near the ground (from sonic anemometer at 4.5 m and first layer of sodar at 30–40 m) did not exceed 3–4 m s−1. The onset of breeze circulation was detected based on surface layer measurements of air temperature (platinum sensor and acoustic), wind speed and direction, and turbulence parameters. The sodar measurements revealed the vertical structure of the wind field.
