The present biogeochemical parameters were measured or calculated in 2013 during a long-term mesocosm CO2 perturbation study in Gullmar Fjord (Sweden). The natural plankton community was enclosed in ten pelagic mesocosms following the natural winter-to-summer plankton succession. Five of the mesocosms were enriched with CO2 to simulate end-of the century ocean acidification (760 µatm) while the others served as controls. The data set was used for mass balance calculations to investigate the impact of realistic end-of-the-century CO2 concentrations on the development and partitioning of the carbon, nitrogen, phosphorus, and silica pools in a coastal pelagic ecosystem.
