Monitoring and Forecasting the Biogeochemical State of the Indian Ocean
The Indian Ocean is an ideal laboratory to understand physicalbiological coupled processes across water column using the models which integrate ocean simulation, observation, and analysis. Ocean models have a unique ability to integrate our empirical and theoretical understanding of the marine environment and the role ocean physics plays in marine environmental health and ecosystem functioning in the coastal ocean and adjacent deepsea. A high-resolution, coupled ocean-ecosystem modeling system, known as Biogeochemical State of the Indian Ocean (BIO), has been developed to study the evolution of the biogeochemical state of the Indian Ocean at both short and long time scales. The modeling framework involves an online coupling of the Regional Ocean Modeling System (ROMS) physics/dynamics integrated with an ecosystem model. This high-resolution BIO modelling system has not only overcome the operational difficulties in generating Potential Fishing Zone (PFZ) advisories due to the non-availability of remote sensing data but also graduated PFZ advisories into PFZ forecasts.
