Ocean acidification increases the agony of the Baltic Sea
Because of low alkalinity and high primary production, the daily fluctuation of pH in the surface water is already high, and ocean acidification is projected to increase this variation further.
The ever-increasing carbon dioxide (CO2) concentrations in the atmosphere result in global warming. Yet a significant share of the CO2 is also taken up by surface oceans. This buffering effect mitigates climate change, but at the cost of causing ocean acidification (OA), or shifts in the acid-base equilibria of seawater. OA means that the pH of the ocean is decreasing.
