Biological effects of OCA

When eelgrass was grown for a year under ocean acidification conditions in outdoor aquaria, they had greater reproductive output, below-ground biomass, and proliferation of new shoots. The [...]

The Kiel Fjord (Baltic Sea) has large natural variations in carbon dioxide levels. When barnacles from the fjord were raised for 8-12 weeks in warmer seawater under ocean [...]

Experiments with deep-sea and shallow-water crab species from the U.S. west coast indicated that deep-sea animals, which are adapted to a stable environment and have reduced metabolic rates, lack [...]

The copepod Calanus finmarchicus had reduced growth, development, and fecundity when exposed to ocean acidification conditions. However, offspring in the next generation did not have delayed [...]

The heat tolerance of a crab species was affected higher concentrations of carbon dioxide. (Laboratory study)

This study investigated how 16 intertidal seaweed species from southern Spain used inorganic carbon under different levels of ocean acidification conditions. (Laboratory study)

After six months exposure, warmer temperatures, but not ocean acidification, significantly reduced the shell strength of blue mussels, which were fed for a limited period of only 4-6 hours per [...]

Hard shell clams and eastern oysters exposed to moderate warming and ocean acidification conditions showed no sign of persistent oxidative stress. This indicates that long-term exposure to [...]

Exposure to extreme ocean acidification conditions (pH 6.95) did not affect growth of adult female copepods. However, only 4 percent of their eggs successfully yielded larvae.

Through combined physical and chemical surveys of water properties, as well as biological sampling, along the Washington-Oregon-California coast in August 2011, this study showed that large [...]
