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 ...
Krill from the northern Atlantic Ocean exposed to ocean acidification conditions for 5 weeks had lower survival rates. (Laboratory study)
Adult green sea urchins exposed to ocean acidification conditons for 56 days ate less food and had 67 percent less growth of their sex glands (gonads). (Laboratory study)
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 ...
Bryozoan colonies were able to survive short-term exposure to high levels of ocean acidification at normal temperatures. However, its ability to calcify at higher temperatures was compromised.
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 ...
The current fraction of total anthropogenic CO2 emissions stored in the ocean appears to be about one-third of the long-term potential.
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
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)
