| Research Abstract |
Impact of ocean acidification, caused by the anthropogenic increase of atmospheric carbon dioxide, on coastal marine species was examined with state-of-art carbon dioxide manipulation system. The actual variability of partial pressure of carbon dioxide in coastal seawater has been observed with a newly designed instrument with tube equilibrator at Sesoko Observatory of University of Ryukyus for one year. The amplitude was considered for the culture experiment of coastal species. Impact of diurnal variability of seawater partial pressure of carbon dioxide was minor for several species in sea urchins, snails and corals, however, it was detectable at near future level of atmospheric carbon dioxide concentration. Outdoor culture tanks with manipulating partial pressure of carbon dioxide was designed and tested. The large flow rate of seawater and natural light condition enabled good experimental design of ocean acidification impact study.
