Estimation of Carbon, Nitrogen and Phosphorous in Macrophyta Biomass on the Sopot Beach (Southern Baltic)

G. Kowalewska, K. Bucholc & M. Szymczak-Zyla
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...
