This research is focused on quantifying the role of light intensity and organic complexation on rainwater iron speciation. Preliminary data indicate that there is both seasonal and diurnal variability in iron speciation. The results of this research are relevant to atmospheric processes that affect the oxidative capacity of the atmosphere and to the lifetime and bioavailability of iron as a nutrient and its influences on marine primary productivity.

本研究的重点是量化光照强度和有机络合作用对雨水铁形态的影响。初步数据表明，铁的形态既有季节变化，也有日变化。本研究结果与影响大气氧化能力的大气过程有关，也与铁作为营养物的寿命和生物利用度及其对海洋初级生产力的影响有关。
