Coastal waters are unique ecosystems and they are very important in terms of living resources and oceanographic processes. Although numerous studies on species composition, primary production and eutrophication have been carried out in the Black Sea, water masses very near coastal areas have been generally omitted due to security issues or undergoing oceanographic research strategy. This study mainly deals with species diversity, composition and abundance as well as some associated physical parameters of the Anatolian Coast of the Black Sea. A total of 40 species belonging to two major taxa Bacillariophyceae (diatoms) and Dinophyceae (dinoflagellates) were identified. The research area was dominated by diatom. CTD data showed a relatively homogeneous water column reaching up to 40-50 m with an average temperature of 13-14 degrees C, 16-17 parts per thousand in salinity and sigma-theta around 13-14 kgm(-3). Chl-a was between 0.15-0.77 mgm(-3) and surface Chl-a maxima were observed in all sampling stations. K-d (PAR) and TSM values were within the limits of the seasonal average.
