Biological effects of OCA

When exposed to ocean acidification conditions (pH 7.7) for 80 days, coralline algae survived by increasing their calcification rates. However, those algae for which the pH had been dropped [...]

Experiments with quahogs exposed to trace metal pollutants under ocean acidification conditions revealed complex interactions and indicated that variations in environmental CO2 may modulate the [...]

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. [...]

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

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, [...]

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 [...]

Ocean acidification caused Eastern oysters and hard shell clams to accumulate more metal pollutants, which affected their physiology. (Laboratory study)

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

In larval scallops, ocean acidification (pH 7.4–7.6) reduced survivorship by more than 50 percent. Low-oxygen water inhibited growth and metamorphosis. When exposed to both low oxygen and ocean [...]

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 [...]
