The Black Sea, a land-locked deep basin with sulfide bearing waters below 150–200m, has been subject to anthropogenic pressures since the 1970s. Large inputs of nutrients (nitrate — N, phosphate — P, silicate — Si) with high N/P but low Si/N ratios and subsequent development of intensive eutrophicat...
