Survival and settling of larval Macoma balthica in a large-scale mesocosm experiment at different fCO2 levels
Anthropogenic carbon dioxide (CO2) emissions are causing severe changes in the global inorganic carbon balance of the oceans. Associated ocean acidification is expected to pose a major threat to marine ecosystems worldwide, and it is also expected to be amplified in the Baltic Sea where the system i...
