Sea stars collected in Nova Scotia, Canada, grew more slowly under ocean acidification conditions, and their growth rate decreased further with a warmer temperature. In contrast, blue mussel grew [...]

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 [...]

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 [...]

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 [...]

Some copepods (Calanus species) in the Arctic routinely encounter a range of seawater pH levels each day as they migrate vertically in the ocean; they were not severely affected when exposed [...]

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 [...]

Deep-water prawns (Pandalus borealis) exposed to severely acidified seawater (pH 6.86) for 16 days were able to compensate by accumulate buffering bicarbonate ions at levels comparable to those [...]

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 [...]
