Calcification

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 [...]

This study investigated changes in mineralization in 18 species of marine calcifiers, which were reared for 60 days in different levels of ocean acidification conditions. The results suggest that [...]

Bryozoan colonies were able to survive short-term exposure to high levels of ocean acidification at normal temperatures. However, its ability to calcify at higher temperatures was compromised.

Estuarine waters are more susceptible to acidification because they are subject to multiple acid sources and are less buffered than marine waters. Consequently, estuarine shell-forming species [...]

The shell calcification rates of small hard clams in five size classes (0.39, 0.56, 0.78, 0.98, and 2.90 mm shell height) decreased with increasingly severe ocean acidification conditions [...]

The shells of eastern oysters from the Chesapeake Bay dissolved at faster rates when exposed to increasingly severe ocean acidification conditions. Oysters with fresh shells dissolved at the [...]

The continental shelf region off the west coast of North America is seasonally exposed to water with a low aragonite saturation state by coastal upwelling of CO2-rich waters. To date, the spatial [...]

Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges [...]
