Background and Introduction:

The Ocean State Forecast (OSF) Service, which is one of the flagship services of ESSO-INCOIS, uses a suit of state-of-the art numerical ocean circulation and wind-wave models to generate necessary forecasts and advisories on the state of the oceans for the benefit of a large spectrum of users. During the 12th five year plan, ESSO-INCOIS has setup a series of very high-resolution (varying from 250m to 2.25 km) ocean circulation and wind-wave models for the coastal waters around the country as well as models for the Indian Ocean basin and the global oceans. In addition, there has been significant progress in implementing data assimilation schemes (which are necessary to initialize the ocean models for generating forecasts) and biogeochemical modules (that can simulate the marine ecosystem parameters) in the ocean circulation models. Since the accuracy of the ocean state forecasts depends largely on the quality of these numerical models, it is important to improve the skills of these models. With this aim, ESSO-INCOIS would like to continue the efforts in numerical ocean modeling, data assimilation and ecosystem modeling. It is found that in order to improve the quality of the simulations/forecasts of ocean models, it is important to improve the representation of physical processes such as vertical and horizontal mixing/advection, dynamics of the formation and evolution of eddies/fronts, swells and wind-sea, etc in these models. This requires systematic and targeted observations of these processes using state-of the art ocean observation techniques. Hence, it is proposed to carry out observational campaigns necessary for measuring the physical/biogeochemical parameters of specific processes/features and setup ocean observation systems to continuously monitor these processes in this project. Data from the campaigns and observational platforms will be used to improve the representation of these processes in the numerical ocean models. In addition to this, it is also proposed to developed user-specific (such as Indian Navy) ocean forecast and information systems and coupled ocean-atmosphere regional ocean forecast system for the Indian coastal waters through this project. It is also envisaged in this project that the sea level changes, particularly in the Indian coastal regions, as a response of global warming will also be studied and projections of these changes will be generated.
