Survival and settling of larval Macoma balthica in a large-scale mesocosm experiment at different f CO 2 levels
Anthropogenic carbon dioxide (CO 2 ) 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...

Anthropogenic carbon dioxide (CO 2 ) 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 is already exposed to relatively large natural seasonal and diel pH fluctuations. We studied the responses of larvae of the benthic key species Macoma balthica to a range of future CO 2 scenarios using six ∼ 55 m 3 mesocosms encompassing the entire pelagic community. The mesocosms were deployed in the northern Baltic Sea in June 2012. We focused on the survival, growth and subsequent settlement process of Macoma balthica when exposed to different levels of future CO 2 . The size and time to settlement of M. balthica increased along the CO 2 gradient, suggesting a developmental delay. With ongoing climate change, both the frequency and extent of regularly occurring high CO 2 conditions are likely to increase, and a permanent pH decrease will likely occur.
