Abstract:: Annual dust inputs to the oceans are a major source of iron, providing an essential trace nutrient for productivity and, thus, indirectly modulating the atmospheric levels of climatically important gases such as CO2 and DMS. The novel in situ iron-enrichment studies (IRONEX and SOIREE) used FeSO4, to dramatic effect, and a major advance would be to investigate the effects of dust, not only as a more natural source of iron but also as a supply of other chemical species and particles, which alter the physico-chemical properties of seawater. Preparation for such an experiment requires an investigation of the best options for collection of suitable dust and its deployment from a ship. The results of this study will enable future experiments, designed to further our understanding of coupled ocean-atmosphere biogeochemistry.
