Ocean acidification in the Black Sea

The aim of this report is to inform environmental NGOs on the status of ocean acidification in the Baltic Sea and the Black Sea, and give an insight into the actors working with ocean acidification. Here are presented such information for some countries at the Black Sea: Ukraine, Romania and Bulgaria and a guide for educational tools concerning ocean acidification.

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.

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.
