| Net community production (NCP) and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June-July 2010. Nutrient depleted fjord water with natural plankton assemblages, enclosed in nine mesocosms of similar to 50m(3) in volume, was exposed to pCO(2) levels ranging initially from 185 to 1420 mu atm. NCP estimations are the cumulative change in dissolved inorganic carbon concentrations after accounting for gas exchange and total alkalinity variations. Stoichiometric coupling between inorganic carbon and nutrient net uptake is shown as a ratio of NCP to a cumulative change in inorganic nutrients. Phytoplankton growth was stimulated by nutrient addition half way... |
