Ocean acidification levels predicted for 2100 (seawater pH 7.8) did not significantly affect growth, arm regeneration, biochemical composition, or righting behavior of a sea star. (Laboratory study)

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 [...]

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

Exposure of early life stages of a common estuarine fish (inland silverside) to ocean acidification conditions expected in the world’s oceans later this century reduced survival by 74 percent and [...]

Blue mussels from the Kiel Fjord (Baltic Sea), where seawater pH tends to be low, were able to maintain growth rates when exposed to ocean acidification conditions (pH 7.7). in addition, juvenile [...]

Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In [...]

Brittlestar arms regenerated faster in warmer water. However, they did not do so when the temperature increase was accompanied by ocean acidification conditions. This may have occurred because [...]

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

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

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