These guidelines are written for a variety of audiences ranging from shellfish growers interested in monitoring pH with inexpensive equipment to citizen monitoring groups to advanced chemistry laboratories interested in expanding existing capabilities. The purpose is to give an overview of available sampling, analytical and data reporting approaches that will ...

This four-page brochure provides an introduction to ocean and coastal acidification, its effects on marine life, why the Northeast is especially vulnerable, research priorities for the region, and what people can do to fight coastal acidification. The information in the brochure is adapted from NECAN's 2015 Oceanography article. 

Under extreme ocean acidification conditions (pH 6.8), the egg production rates of copepods decreased significantly. For two species of sea urchins, fertilization rate of eggs decreased with increasing ocean acidification conditions. Furthermore, the size of urchin larvae decreased and deformities increased. These effects on marine life could lead to changes ...

Bacterial infection of blue mussels increased under ocean acidification conditions. (Laboratory study)

Ocean and coastal acidification is occurring due to uptake of atmopsheric CO2, as well as nutrient-fueled respiration in some estuarine and costal environments. Multiple stressors, influenced by human activity, affect the patterns and severity of acidification. Temperature, deoxygenation, and changes in food webs are particualarly important co-stressors. Development of a ...

Through combined physical and chemical surveys of water properties, as well as biological sampling, along the Washington-Oregon-California coast in August 2011, this study showed that large portions of shelf water were corrosive to pteropods. A strong correlation between aragonite saturation state and pteropod shell dissolution is shown. It is estimated that ...

This Oceanography article discusses the effectiveness and limitations of current research approaches used to understand how marine ecosystems and global elemental cycles will respond to changes in seawater carbonate chemistry in combination with other environmental perturbations such as warming, eutrophication, and deoxygenation.
