Calcification

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 [...]

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)

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 [...]

When grown under ocean acidification conditions, a non-calcifying seaweed (Chondrus crispus) grew to cover more area, while a calcifying alga (Corallina officinalis) decreased in the area it [...]

In larval scallops, ocean acidification (pH 7.4–7.6) reduced survivorship by more than 50 percent. Low-oxygen water inhibited growth and metamorphosis. When exposed to both low oxygen and ocean [...]

The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of [...]

Calcification rates of the blue mussel and the Pacific oyster decline with increasing ocean acidification. Mussel and oyster calcification may decrease by 25 percent and 10 percent, respectively, [...]

When a coralline alga was exposed to both ocean acidification and solar UV radiation, its growth, photosynthesis, and calcification rates were greatly reduced, compared to when it was exposed [...]
