Description of the workshop

Recent progress on the Indian Ocean Observing System (IndOOS) has significantly promoted the understanding of the monsoon-ocean interaction and the role of the ocean in climate variations over a wide spectrum of time scales from intra-seasonal to inter-decadal, with global relevance and also specific relevance to the constituency of the Indian Ocean Global Ocean Observing System Regional Alliance (IOGOOS). Stimulated by this basin-scale progress, a new endeavour towards developing an interdisciplinary Eastern Indian Ocean Upwelling (EIOU) research initiative, involving its dynamical characterization and related ecosystem impacts, has been identified as an emerging multidisciplinary research priority by the Indian Ocean Panel (IOP) (under CLIVAR, GOOS and IOGOOS) and the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER) program (under IOGOOS and IMBER). It will also be a key component of the planned 50th Anniversary Celebration of the International Indian Ocean Expedition (IIOE-2). Interdisciplinary upwelling research has been identified as a high priority within CLIVAR as well. EIOU, compared with the Western Indian Ocean Upwelling (WIOU), is much less observed and understood. The monsoon-forced essence associated with the EIOU also distinguishes it from upwelling in other basins. Therefore, it deserves urgent scientific attention given the critical role it plays in basin to global scale climate (for example, relating to the Indian Ocean Dipole) and marine ecosystem and fishery dynamics.

This workshop will review the past research relevant to EIOU and EIOU-WIOU contrasts, existing gaps in observational requirements to understand EIOU, summarize the outcomes of intensive discussion from two EIOU-targeted workshops planned respectively in April and November 2013, finalize the EIOU science and observational plan, discuss and refine the EIOU working plan for 2015-2020 time frame and IIOE-2.
