%X Based on the samples collected from Dongshan Bay during in August and November 2008 for the field observation, the concentrations of total dissolved iron, Fe(II), Fe(III), chlorophyll a, nutrients, and other parameters were determined and discussed in this paper. Both of the concentration of Fe (II) and the percentage of Fe (II) of total dissolved iron were positive correlation with chlorophyll a and the correlation coefficients were 0.7959 and 0.9219, respectively. According to the results from the mesocosm experiments, total dissolved iron was depressed 17.4% during 24 hours, while the concentration of Fe(II) and the percentage of Fe(II) of total dissolved iron were increased. The concentration of Fe (II) in seawater from DS2 where marine phytoplankton was abundant was more than that from DS5 which was lacking of phytoplankton. Enrichment experiments of Fe(II) and Fe(III) were set up to study the transformation between Fe(II) and Fe(III). The results showed that Fe(II) was oxidized rapidly in seawater, and Fe(III) was reduced to Fe(II) by the light-induced photochemical activity of marine phytoplankton.
