Upwelling systems and associated ocean variability in the eastern Indian Ocean play an important role in biophysical interactions in marine ecosystems as well as in regional and basin scale climate variations. Due to sparseness of in situ observations, however, much of details on variability in the upwelling systems are still unveiled. To enhance our understanding on physical and biogeochemical/ecosystem variability associated with the upwelling systems in the eastern Indian Ocean, an international research initiative, named Eastern Indian Ocean Upwelling Research Initiative (EIOURI), is proposed as a part of IIOE-2 during 2015-2020. EIOURI includes an intensive observation campaign together with modeling and analyses of data from various sources. This research initiative mainly focuses on the coastal upwelling system off Sumatra-Java, but also includes open ocean and coastal upwelling systems in the Bay of Bengal, equatorial region, and area off northwestern coast of Australia as its target areas. Main topics of the initiative include; local and remote influences of oceanic processes on the upwelling systems, coastal and off-shore interactions, biogeochemical variability and their interactions with physical conditions, ecosystem variability associated with the upwelling variations. This presentation introduces science plan of EIOURI and discuss several specific key issues to be investigated during the initiative.
