This report describes climatological mean monthly distributions of pH, total carbon dioxide concentration, and the degree of CaCO3 saturation for the global surface ocean waters (excluding coastal areas) to depths of approximately 160 feet (50 meters).
The carbonate system of the Baltic Sea is strongly influenced by the input of low salinity waters during spring and summer originating from the Bothnian Sea, the Gulf of Finland and the Gulf of Riga as well as by the input of high salinity waters during autumn and winter originating ...
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
Video analysis of Atlantic cod larvae (12 and 27 days post-hatch) showed no significant differences in most aspects of their swimming kinematics when they had been cultured under ocean acidification conditions. (Laboratory study)
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 moderately elevated CO2 and temperature minimally affects the cellular redox status in these bivalve species and that the earlier observed negative physiological effects ...
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.
Viability of copepod eggs and larvae was not affected by exposure to ocean acidification conditions. In contrast, warming by 2 or 4°C increased the viability of some eggs. (Laboratory study)
Egg production and hatching success of two copepod species was not affected by ocean acidification conditions during short-term incubations. (Laboratory study)
Common periwinkles had lower shell growth rates and less increase in shell thickness when grown in ocean acidification conditions, warmer temperatures, or both. Shells were also less pointed and more rounded. Those changes in shell growth appeared to result from disruption of the periwinkle's metabolism. (Laboratory studied)
