dc.description.abstractAtmospheric deposition of pollutants decreases pH and increases the nutrient concentration in the surface water.To examine its impact on coastal phytoplankton composition and primary production, monthly atmospheric aerosol samples were mixed with coastal waters in the microcosm experiments.These experiments suggested that the biomass of Bacillariophyceae, Dinophyceae and Chlorophyceae were increased and primary production of the coastal waters increased by 3 to 19% due to the addition of aeolian nutrients.The increase in primary production displayed significant relation with a concentration of sulphate and nitrate in the atmospheric aerosols suggesting that both decreases in pH and fertilization enhanced primary production.The impact of acidification on primary production was found to be 22%, whereas 78% was contributed by the nutrient increase.The atmospheric pollution is increasing rapidly over the northern Indian Ocean since past two decades due to rapid industrialization.Hence, it is suggested that the impact of atmospheric pollution on the coastal ecosystem must be included in the numerical models to predict possible changes in the coastal ecosystem due to climate change.
