1 Fertilization by Dust Promotes Oceanic Biomass Phytoplankton produce most of the oceanic biomass through photosynthesis Iron from atmospheric dust is a key nutrient for phytoplankton and photosynthesis However, sun, wind and other factors influence the production of chlorophyll Bishop et al.(2002), Science Evidence in the N. Pacific DustWindSun Chlorophyll

2 Fertilization by Dust Promotes Oceanic Biomass Phytoplankton produce most of the oceanic biomass through photosynthesis Iron from atmospheric dust is a key nutrient for phytoplankton However, many other factors influence the generation of phytoplankton chlorophyll Dust Bishop et al.(2002), Science Evidence in the N. Pacific

3 Is Dust Enhancing Chlorophyll over the Eastern Med? Chlorophyll surge occurs after dust events… but dust events are also associated with high winds Science Question: What are the relative roles of: Iron-phosphorus fertilization by dust? Enhanced mixing in high winds? François DULAC*, Cyril MOULIN, Hélène PLANQUETTE, Michael SCHULZ, Michael TARTAR Sahara Dust is abundant over the Mediterranean The dust and the chlorophyll can be quantified by satellite data
