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 [...]

Four species of pteropods from the tropical Pacific Ocean that naturally migrate into low-oxygen waters were not adversely affected when grown under ocean acidification conditions. However, [...]

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 [...]

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

Carbon dioxide partial pressure and vitamin B12 interactively influenced growth, carbon fixation, trace metal requirements, and trace metal net use efficiencies of the subarctic [...]

Between 1959 and 2008, 43 percent of each year’s carbon dioxide emissions remained in the atmosphere on average. The rest was absorbed by carbon sinks on land and in the ocean.

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 [...]

When pre-winter juvenile pteropods were cultured at a range of warmer temperatures and ocean acidification levels for 29 days, temperature was the overriding cause of increased mortality. [...]

Spider crab larvae developed more slowly, grew less, and lower physiological fitness under increasing levels of ocean acidification conditions. (Laboratory study)

Krill from the northern Atlantic Ocean exposed to ocean acidification conditions for 5 weeks had lower survival rates. (Laboratory study)
