| Popis: | Macrophyta (macroalgae + some seagrass) mats which can float to far distances and accumulate at the beach in the middle of touristic season are a great problem of Sopot, resort located on the coast of the Gulf of Gdansk (southern Baltic). This phenomenon happens to be accompanied by the toxic blue-algae blooms, though their biomass is negligible small comparing with macrophyta. Both the macroalgae and blue-green algae blooms result from eutrophication. The beach, situated in the middle of the town, is closed in such cases. Decomposing at the shore of the algae with addition of seagrass and planktonic organisms give off odour, which considerably decreases the recreation values of the beach. Neither macroalgae nor seagrass grow near the beach. They are transported here by winds of appropriate speed and direction waves and currents, and due to that their appearance at the beach are not permanent and not regular. Also, the vegetation of these macrophyta in the Baltic coastal zone depends on meteorological conditions and nutrient input to the water column. In result, amounts of this biomass are difficult to forecast. Proceedings of the 20th European Biomass Conference and Exhibition, 18-22 June 2012, Milan, Italy, pp. 435-435 |
