Carbon cycle is connected with the most important environmental issue of Global Change.As one of the major carbon reservoirs, oceans play an important part in the carbon cycle. In recentyears, iron seems to give us a good news that oceanic iron fertilization could stimulate biological produc-tivity as CO2 sink of human-produced CO2. Oceanic iron fertilization experiments have verified thatadding iron into high nutrient low chlorophyll (HNLC) seawaters can increase phytoplankton productionand export organic carbon, and hence increase carbon sink of anthropogenic CO2, to reduce globalwarming. In sixty days, the export organic carbon could reach 10 000 times for adding iron by modelprediction and in situ experiment, I.e. The atmospheric CO2 uptake and inorganic carbon drawdown inupper seawaters also have the same magnitude. Therefore, oceanic iron fertilization is one of the strate-gies for increasing carbon sink of anthropogenic CO2. The paper is focused on the iron fertilization, es-pecially in situ ocean iron experiments in order that the future research is more efficient.
