Atmospheric depositions of nutrients (N, P, and Fe) modulate primary ocean productivity and thus indirectly affect the climate. Significant progresses have been made in our understanding of natural and anthropogenic atmospheric inputs of nutrients to the ocean. However, there are still large uncertainties concerning the sources and delivered amounts of bioavailable iron, as well as the effects of air pollution on the solubility, and thus bioavailability. This talk will focus on atmospheric chemistry of bioavailable iron input to the ocean. The atmospheric chemistry transport model is useful to validate the laboratory results for their application to ambient atmospheric conditions.
