Climatological Distributions of pH, pCO2, Total CO2, Alkalinity, and CaCO3 Saturation in the Global Surface Ocean
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 seasonal cycle of carbon dioxide in Baltic Sea surface waters
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 ...
Coastal Acidification to Rivers: A Threat to Shellfish?
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.
The swimming kinematics of larval Atlantic cod, Gadus morhua L., are resilient to elevated seawater pCO2
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)
Interactive effects of elevated temperature and CO2 levels on metabolism and oxidative stress in two common marine bivalves (Crassostrea virginica and Mercenaria mercenaria)
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 ...
CO2-induced acidification affects hatching success in Calanus finmarchicus
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.
End of century ocean warming and acidification effects on reproductive success in a temperate marine copepod
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)
Effects of elevated CO2 on the reproduction of two calanoid copepods
Egg production and hatching success of two copepod species was not affected by ocean acidification conditions during short-term incubations. (Laboratory study)
Effects of ocean acidification and elevated temperature on shell plasticity and its energetic basis in an intertidal gastropod.
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)
