Impacts of elevated CO2 on phytoplankton growth and organic matter production were examined using isolates and in situ plankton communities. Responses to the CO2 increase were species-specific and were altered in different temperature and light conditions. Although in situ plankton communities did not show major responses to the CO2 increase, clear trends to the CO2 increase were observed in some experiments. Future CO2 increase in seawater can play a significant role on altering the dynamics of in situ phytoplankton communities and organic matters.

利用分离物和原位浮游生物群落研究了CO2升高对浮游植物生长和有机物生产的影响。对CO2增加的响应具有物种特异性，并且在不同的温度和光照条件下发生变化。虽然原位浮游生物群落对CO2增加没有表现出主要的响应，但在一些实验中观察到CO2增加的明显趋势。未来海水中CO2的增加对改变原位浮游植物群落和有机质的动态具有重要作用。
