1. Dust and Chlorophyll over the Mediterranean GEOSS Web Services (GWS) Interoperability Demostration Presented at the workshop The User and the GEOSS Architecture July 22, 2007, Barcelona, Spain

2. Ocean Fertilization by Atmospheric Dust Phytoplankton produce most of the oceanic biomass through photosynthesis Photosynthesis by chlorophyll has been shown to increase with atmospheric dust fertilization Bishop et al.(2002), Science Evidence of Chlorophyll Enhancement by Dust DustWindRain Chlorophyll However, precipitation, the wind and many other factors also influence the production of chlorophyll A scientific challenge is to quantify the chlorophyll-dust relationship E. Mediterranean N. Pacific Ocean Oceanic Biomass by Phytoplankton

10. Summary GEOSS System of Systems architecture is suitable for integrating data across geographical, disciplinary and organizational boundaries. The current data access standardization is very spotty and fragile but non-intrusive mediator services can bridge the interoperability gaps. Interoperability demonstrations are key steps toward configurable, robust data flow and processing networks.

11. How is Dust Influencing 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 as shown in historical records, surface observations and satellite sensors Oceanic chlorophyll is also measurable through satellite and in situ sensors Tag with Barcelona + GEOSSDe mo
