Blue mussels from the Kiel Fjord (Baltic Sea), where seawater pH tends to be low, were able to maintain growth rates when exposed to ocean acidification conditions (pH 7.7). in addition, juvenile mussels in the fjord settle mostly in summer when pH is lowest. The findings suggest that mussels may ...

Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In addition, the mussels were able to outcompete barnacles at the inner fjord, low pH site. Thus, blue ...

This study investigated changes in mineralization in 18 species of marine calcifiers, which were reared for 60 days in different levels of ocean acidification conditions. The results suggest that shell/skeletal mineralogy within some—but not all—marine calcifiers will change as carbon dioxide levels continue rising as a result of fossil fuel ...

Common periwinkles consumed less food when living under ocean acidification conditions for five weeks, after having been exposed to those conditions for two weeks prior to the experiment. Their food—a biofilm of diatoms, cyanobacteria, and various microbes—increased during that period. However, another group of periwinkles consumed more food than the ...

Growth rate and biomass of a seaweed (the red alga Chrondrus crispus) increased only when ocean acidification was accompanied by warmer temperatures. Photosynthesis was reduced under ocean acidification conditions. (Laboratory study)
