Abstract
Ocean uptake of CO2 will help moderate future climate change, but the subsequent hydrolysis of CO2 in seawater increases the hydrogen ion concentration. The increase of dissolved [CO2] itself can influence the physiology and biochemistry of marine organisms by changing the aragonite/calcite ratio and also decreasing the pH of body fluid in addition to the seawater acidification. To evaluate the increase of dissolved [CO2] on the various marine organisms, we exposed bioluminescent bacteria, amphipods, copepods and fishes under different [CO2] in air and water. Slight increase of [CO2] from background level could adversely affect the growth and bioluminescence of microbes when exposed for less than 12 h, however, they could recover after 18 hr of exposure. Amphipods and fishes could tolerate the unrealistically high level of [CO2], but the population growth of copepods was significantly influenced by dissolved [CO2] in seawater. To mitigate the impact of the future atmospheric CO2 increase, the ocean CO2 sequestration has been proposed recently. The results of this study will be useful to predict the risks of the increase of CO2 concentrations in seawater due to the increase of atmospheric CO2 emission and also predict the potential risks due to the release from stored CO2 in seabed or deep ocean
