Effect of ocean acidification on the structure and fatty acid composition of a natural plankton community in the Baltic Sea
Increasing atmospheric carbon dioxide (CO 2 ) is changing seawater chemistry towards reduced pH, which affects various properties of marine organisms. Coastal and brackish water communities are expected to be less affected by ocean acidification (OA) as these communities are typically adapted to hig...

Increasing atmospheric carbon dioxide (CO 2 ) is changing seawater chemistry towards reduced pH, which affects various properties of marine organisms. Coastal and brackish water communities are expected to be less affected by ocean acidification (OA) as these communities are typically adapted to high fluctuations in CO 2 and pH. Here we investigate the response of a coastal brackish water plankton community to increasing CO 2 levels as projected for the coming decades and the end of this century in terms of community and biochemical fatty acid (FA) composition. A Baltic Sea plankton community was enclosed in a set of offshore mesocosms and subjected to a CO 2 gradient ranging from natural concentrations ( ∼ 347 µatm f CO 2 ) up to values projected for the year 2100 ( ∼ 1333 µatm f CO 2 ). We show that the phytoplankton community composition was resilient to CO 2 and did not diverge between the treatments. Seston FA composition was influenced by community composition, which in turn was driven by silicate and phosphate limitation in the mesocosms and showed no difference between the CO 2 treatments. These results suggest that CO 2 effects are dampened in coastal communities that already experience high natural fluctuations in p CO 2 . Although this coastal plankton community was tolerant of high p CO 2 levels, hypoxia and CO 2 uptake by the sea can aggravate acidification and may lead to pH changes outside the currently experienced range for coastal organisms. |
