ABSTRACT :

The Eastern Indian Ocean Upwelling Research Initiative (EIOURI) is a broad international collaborative program that is developing as part of IIOE2 with a focus on the upwelling region south of Java. EIOURI will include major efforts to understand physical mechanisms that drive the seasonal onset and decline of upwelling in the region, as well as its inter-annual variability, and associated mesoscale dynamics and advective transport. These physical investigations provide, in turn, a context for advancing biogeochemical and ecological understanding of this complex and poorly studied region, including elemental and population exchanges through the ITF, carbon and nutrient cycling, responses of community structure and function to physical forcing, and the production rates and fates of organisms and organic matter in the resulting food webs. In the present talk, we will highlight project planning to investigate end-to-end food-web relationships connecting nutrient sources, primary productivity, trophic fluxes and growth environment for tuna species downstream of the Java upwelling.
