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.

The copepod Calanus finmarchicus had reduced growth, development, and fecundity when exposed to ocean acidification conditions. However, offspring in the next generation did not have delayed development, suggesting that the species may have an ability to adapt to ocean acidification. The results also suggest that in a more acidified ocean ...

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 ...

Ocean acidification conditions suppressed the metabolism of an Antarctic pteropod by approximately 20 percent in some instances. However, the effect on metabolism depended on abundance of phytoplankton in the region and the pteropods' baseline level of metabolism. Pteropod populations may be compromised by climate change, both directly by acidification-related suppression ...

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 ...

The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of a general picture. This is, however, not the case for pteropods, with all species tested so far, being negatively ...

Over the contiguous United States, precipitation, temperature, streamflow, and heavy and very heavy precipitation increased during the twentieth century. 

This study used two methods to estimate the exchange of carbon dioxide between the atmosphere and ocean.

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean 7.8–7.9, minimum 7.4–7.5), typical rocky shore communities with abundant calcareous organisms shifted to communities lacking scleractinian corals ...

Under conditions expected in the 21st century, global warming and ocean acidification will cause corals to become increasingly rare on reef systems. This review presents future scenarios for coral reefs that predict increasingly serious consequences for reef-associated fisheries, tourism, coastal protection, and people.
