Ecosystem

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean [...]

This study used two methods to estimate the exchange of carbon dioxide between the atmosphere and ocean.

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 [...]

Common periwinkles consumed less food when living under ocean acidification conditions for five weeks, after having been exposed to those conditions for two weeks prior to the experiment. Their [...]

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.

Ocean acidification conditions suppressed the metabolism of an Antarctic pteropod by approximately 20 percent in some instances. However, the effect on metabolism depended on abundance [...]

Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to [...]

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 [...]

Three direct effects of increasing ocean acidification on marine plankton have been recognized: enhanced phytoplankton growth rate, changing elemental composition of primary produced organic [...]

Appendicularians are free-swimming tunicates that are common in most oceans, coastal waters, and estuaries. They build delicate, gelatinous houses that they use to filter food from the water. [...]
