At an oyster hatchery on the Oregon coast, researchers found that production of oyster larvae and growth of young oysters dropped when the aragonite saturation state decreased in seawater. (Laboratory study)
Brittlestar arms regenerated faster in warmer water. However, they did not do so when the temperature increase was accompanied by ocean acidification conditions. This may have occurred because the brittlestars had to devote more of their energy to maintaining calcium carbonate body parts, as calcium carbonate became undersaturated when the ...
The amount of available phosphorus appeared to regulate how much inorganic carbon was used by a red alga grown at different levels of ocean acidification conditions. Growth reflected a balance between carbon and nutrient metabolism. (Laboratory study)
Ten species of zooplankton displayed a range of mortality rates when exposed to ocean acidification conditions. Differences in in swimming behavior, food habits, size, and presence of gills were not significantly related to sensitivity to lowered pH. The results suggest that marine zooplankton are more sensitive than freshwater zooplankton to ...
The combined effect of ocean acidification and rising temperature enhanced the sensitivity of a red alga to ultraviolet (UV) radiation. This was reflected in an increased damage rate, decreased repair rate, and decreased ratio of repair to damage in thalli. The findings suggest that ocean acidification and warming will reduce ...
More than 98% of the carbon of the atmosphere-ocean system is stored in the oceans as dissolved inorganic carbon. This textbook describes equilibrium and nonequilibrium properties and stable isotope fractionation among the elements of the carbonate system.
The egg production rate, hatching success, and respiration of a Mediterranean copepod were not affected by ocean acidification conditions. Warming and food availability did have some effects. (Laboratory study)
Four species of copepods differed in their survival, egg production, and egg hatching success when exposed to ocean acidification conditions for 8 days. (Laboratory study)
Eelgrass was able to photosynthesize better under ocean acidification conditions because of increased availability of carbon dioxide. The results suggest that ocean acidification may enhance seagrass survival.
