CO2 / pCO2

Ocean acidification increased the negative effects of cadmium pollution on the immune systems of quahogs and eastern oysters, potentially making them more vulnerable to pathogens and disease. [...]

Weekly growth rate of a cold-water seaweed (Porphyra linearis) averaged 53% in regular air and 28% in CO2-enriched air. (Laboratory study)

Experiments with blue mussels from the Baltic Sea revealed a molecular basis of observed changes in physiology in response to ocean acidification. (Laboratory study)

In green sea urchins from the Baltic Sea, the spines appear to be vulnerable to ocean acidification, which might reduce the urchins’ protection against predators. Intestinal epithelia may [...]

Aerobic scope and cardiac performance of Atlantic halibut increased following 14–16 weeks exposure to elevated temperatures and even more so in combination with CO2-acidified seawater. However, [...]

Higher levels of carbon dioxide (CO2) enhanced growth of a green seaweed (Ulva rigida). (Laboratory study)

Calcification rates of the blue mussel and the Pacific oyster decline with increasing ocean acidification. Mussel and oyster calcification may decrease by 25 percent and 10 percent, respectively, [...]

When a coralline alga was exposed to both ocean acidification and solar UV radiation, its growth, photosynthesis, and calcification rates were greatly reduced, compared to when it was exposed [...]

Ocean acidification conditions did not affect survival, body size, or developmental speed of a copepod species during any of its life stages. Egg production and hatching rates also did not change [...]

A non-bicarbonate using red seaweed grew more rapidly with increasing carbon dioxide. (Laboratory study)
