When quahogs and eastern oysters were exposed to a combination of warmer temperatures and ocean acidification for 15 weeks, shell hardness decreased in both species. By itself, ocean acidification had a small effect on the physiology and metabolism of both species, but it improved survival in oysters. (Laboratory study)
Experiments with quahogs exposed to trace metal pollutants under ocean acidification conditions revealed complex interactions and indicated that variations in environmental CO2 may modulate the biological effects of trace metals. (Laboratory study)
Intracellular concentration of DMSP remained unaffected in two macroalgae species (Ulva lactuca and U. clathrata) under ocean acidification conditions, but significant differences in extracellular production of DMSP and DMS occurred in U. lactuca. (Laboratory study)
Carbon dioxide partial pressure and vitamin B12 interactively influenced growth, carbon fixation, trace metal requirements, and trace metal net use efficiencies of the subarctic diatom Attheya sp. (Laboratory study)
A non-bicarbonate using red seaweed grew more rapidly with increasing carbon dioxide. (Laboratory study)
Ocean acidification conditions did not affect survival, body size, or developmental speed of a copepod species during any of its life stages. Egg production and hatching rates also did not change among generations of females exposed to ocean acidification conditions. Thus, this copepod appears more tolerant to ocean acidification than ...
Reproduction and larval development of two copepod species were sensitive to extreme ocean acidification conditions. The hatching rate tended to decrease, and mortality rate of young copepods tended to increase. (Laboratory study)
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 ...
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 acidification. Predation by green crabs on periwinkles did not appear to change under ocean acidification conditions. (Laboratory study) ...
Between 1959 and 2008, 43 percent of each year's carbon dioxide emissions remained in the atmosphere on average. The rest was absorbed by carbon sinks on land and in the ocean.
