Research Abstract

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.
