Biological effects of OCA

Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions [...]

Brittlestar arms regenerated 30 percent more slowly under ocean acidification conditions. (Laboratory study)

The immune responses of grazing isopods (Idotea balthica) in the Baltic Sea dropped by 60 to 80 percent after the isopods were placed in ocean acidification conditions for 20 days. In addition, [...]

Three direct effects of increasing ocean acidification on marine plankton have been recognized: enhanced phytoplankton growth rate, changing elemental composition of primary produced organic [...]

Appendicularians are free-swimming tunicates that are common in most oceans, coastal waters, and estuaries. They build delicate, gelatinous houses that they use to filter food from the water. [...]

Educational introduction to the chemistry and biological impacts of ocean acidification

Educational website about ocean acidification created by the Channel Islands National Marine Sanctuary Education Team.

This study determined the pH tolerance of the embryonic and larval stages of hard clams and oysters. (Laboratory study)

At an oyster hatchery on the Oregon coast, researchers found that production of oyster larvae and growth of young oysters dropped when the aragonite saturation state decreased in seawater. [...]

Ocean acidification (OA) is increasingly recognized as a major global problem. Despite the scientific evidence, economic assessments of its effects are few. This analysis is an attempt to perform [...]
