Parameterizations of how phytoplankton and bacterial growth respond to variations in carbonate chemistry are introduced and applied. The model resolves vertical profiles within a 420 km2 area of OAE, and within a 2.05×105 km2 surrounding region. Both areas are connected and lateral dispersion causes a horizontal exchange of chemical and biological tracers. The analysis comprises 32 pulsed OAE scenarios of varying intensities and frequencies of alkalinity addition. The intensities of OAE are derived as fractions of total CaO available for OAE in Europe, from 0.05 % (low), 0.1 % (moderate), 0.2 % (high) and 0.4 % (extreme). These four intensities are co-varied with four frequencies of OAE: monthly, seasonal, annual-winter, and annual-summer deployments. The study shows how much the frequency of the OAE influences the efficacies determined locally and remotely. The model results also provide some first insight of potential OAE effects on biological production.
