Dissolved Fe(II) was isolated and preconcentrated in situ in the euphotic waters of the equatorial Pacific Ocean, using complexation by Ferrozine previously adsorbed on a C18 hydrocarbon substrate and then determined spectrophotometrically. The distribution of Fe(II) in the surface waters varied temporally and spatially, exhibiting maxima near the surface and often at depths with higher chlorophyll a. Laboratory photochemical experiments with equatorial Pacific seawater demonstrated photochemical reduction of Fe(ill) which may be an important source for Fe(II) in these waters, altering the speciation and bioavailability of iron. A highly sensitive stopped-flow chemiluminescence method was developed for the analysis of Fe(II) and reducible i...
