Granulometric analysis of the Anapa bay-bar sediments (the Black Sea, Russia)

摘要

The paper describes the granulometric characteristics of the large accumulation form sediments (the Anapa Bay-bar). The choice of sampling sites was based on remote sensing data. The analysis of particle size change in 2012 to 2016 has been carried out. The content of carbonate and mineral components in samples collected on the submerge slope has been determined. When comparing the data of 2012 and 2015, it is clear that size structure and composition of sand have not been changed significantly. Analysis of zoobenthos samples shows that the increase in shelly material content is not directly related to the increase in the living mollusks biomass. Sand with a mean particle size of at least 0.3 mm should be used to nourish beaches of the Anapa bay-bar. Smaller material will be washed out to deeper depths or blown away to dunes.
