  abstract = {{T}he dynamics of the aragonite saturation state ({O}mega(arag)) were investigated in the eutrophic coastal waters of {G}uanabara {B}ay ({RJ}-{B}razil). {L}arge phytoplankton blooms stimulated by a high nutrient enrichment promoted the production of organic matter with strong uptake of dissolved inorganic carbon ({DIC}) in surface waters, lowering the concentrations of dissolved carbon dioxide ({CO}2aq), and increasing the p{H}, {O}mega(arag) and carbonate ion ({CO}32- especially during summer. {T}he increase of {O}mega(arag) related to biological activity was also evident comparing the negative relationship between the {O}mega(arag) and the apparent utilization of oxygen ({AOU}), with a very close behavior between the slopes of the linear regression and the {R}edfield ratio. {T}he lowest values of {O}mega(arag) were found at low-buffered waters in regions that receive direct discharges from domestic effluents and polluted rivers, with episodic evidences of corrosive waters ({O}mega(arag) < 1). {T}his study showed that the eutrophication controlled the variations of {O}mega(arag) in {G}uanabara {B}ay.},
