Four species of copepods differed in their survival, egg production, and egg hatching success when exposed to ocean acidification conditions for 8 days. (Laboratory study)

Eelgrass was able to photosynthesize better under ocean acidification conditions because of increased availability of carbon dioxide. The results suggest that ocean acidification may [...]

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 [...]

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

From 1974 to 1985, atmospheric carbon dioxide concentrations at the Mauna Loa Observatory in Hawaii increased an average of 1.42 parts per million annually.

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. [...]

The world’s oceans contain an enormous reservoir of carbon, greater than either the terrestrial or atmospheric systems. The fluxes between these reservoirs are relatively rapid such that the [...]

Copepods produced more eggs in warmer temperatures, but the increase was smaller when copepods were simultaneously exposed to warmer temperature and ocean acidification conditions (lower pH). [...]

The shell calcification rates of small hard clams in five size classes (0.39, 0.56, 0.78, 0.98, and 2.90 mm shell height) decreased with increasingly severe ocean acidification conditions [...]

Thermal sensitivity of spider crabs, as indicated by heart rate, rose under increasing levels of ocean acidification conditions. The results suggest a narrowing of the spider crab’s thermal [...]
