Biological effects of OCA

The common sea star (Asterias rubens) appeared to withstand the effects of reduced seawater pH, at least for short-term exposures of 15 to 27 days, with no significant changes in the strength of [...]

Marine phytoplankton have many characteristics, such as rapid cell division rates and large population sizes, that may enable them to adapt to ocean acidification and other types of global [...]

Calcification rate of pteropods dropped 28 percent at pH levels projected for 2100. This result supports the concern for the future of pteropods in a high-CO2 world, as well as of those species [...]

When larvae of Mediterranean pteropods were cultured in pH 7.82 water, they had malformations and less shell growth. At pH 7.51, the larvae did not make shells but survived and showed normal [...]

Although pteropods are able to build shells at low aragonite saturation state, the production of their shell appears to be very sensitive to decreased pH. (Laboratory study)

Increased CO2 and temperature acted together to increase the growth of algal turfs, which produced twice as much biomass and covered four times as much space. Experimental removal of algal turfs [...]

 Adult copepods living in acidified water had lower egg production and hatching success. (Laboratory study)

Based on experiments with corals collected in Woods Hole, Massachusetts, this paper presents a conceptual model of how changes in nutrients and ocean acidification may interact to produce the [...]

Health of Atlantic halibut may be affected by moderate ocean acidification—by itself and combined with warmer temperatures.

Blue mussels and ocean quahogs from the Baltic Sea appeared to tolerate wide ranges of seawater temperature and ocean acidification over a period of 13 weeks. (Laboratory study)
