pH

Blue mussels in pH 7.1 seawater for 44 days had reduced shell growth, and those in pH 6.8 virtually stopped growing. In less acidified water—pH 7.4 or 7.6—shell growth was not [...]

The release of dimethylsulphoniopropionate (DMSP) by marine algae has major impacts on the global sulphur cycle and may influence local climate through the formation of dimethylsulphide (DMS). [...]

Survival of pteropods in Puget Sound, Washington, may not be greatly affected by present ocean pH levels and those projected for the near future, although their shells may be more prone to [...]

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 [...]

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)

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

This study used Earth system models to examine how four of the major stressors of ocean ecosystems—warming, acidification, deoxygenation, and changes in primary productivity—may evolve over the [...]

Normally, common periwinkles produce thicker shells in the presence of crab predators. This study found that they did not do so when living in acidified seawater for 15 days. The snails [...]
