Calcification

A coralline alga had reduced calcification in ocean acidification conditions. (Laboratory study)

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 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 [...]

Two species of phytoplankton (coccolithophores) had higher rates of deformities when pH of seawater in the laboratory was different from present-day ocean pH. Examination of geological samples of [...]

Bryozoan colonies were grown at a site in the Tyrrhenian Sea (Italy) where natural emissions of carbon dioxide associated with volcanic activity lower seawater pH to 7.76, simulating levels [...]

This study investigated the possible effects of ocean acidification on the calcareous skeleton of a Mediterranena bryozoan by transplanting live and dead colonies into an area of natural volcanic [...]

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.

Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to [...]

Under extreme ocean acidification conditions (pH 6.8), the egg production rates of copepods decreased significantly. For two species of sea urchins, fertilization rate of eggs decreased with [...]
