For utilising the ocean resources in a sustainable way and making the
benefits cost effetive, it is important to understand oceanic
processes. Knowledge of ocean dynamics is a prerequisite for
prediction of ocean state based on ocean models.
5.4.1 Indian Ocean Modelling and Dynamics (INDOMOD)
The programme is designed to generate a wide range of ocean models.
The institutes associated in this enceavor are Centre for
Mathematical Modelling and Computer Simulation (C-MMACS) , National
Institute of Oceanography (NIO), Indian Institute of Technology,
Delhi (IIT-D) and Cochin University. C-MMACS is the nodal agency for
coordination of this project.
The primary objective of the programme are as follows:
Development of basin scale dynamic model using Ocean General
Circulation Model for short and long term state forecast.
Generation of biological coupled model for prediction of seasonal
and inter-annual variations of marine productivity.
To develop mathematical models for tidal wind driven circulation
for assessing the health of the ocean and the coastal zones of India.
To generate coupled ocean atmosphere models for predicting monthly
and seasonal oceanographic parameters to study the oceanographic
process ; for prediction of storm surge associated with tropical
cyclones along the Indian coast and for studying the inter-annual/
decadal variations in the surface ocean for long term prediction of
Indian monsoon and for developing systems for an experimental Ocean
5.4.2 Joint Global Ocean Flux Study - JGOFS (India)
The JGOFS is a core project of International Biosphere-Geosphere
Programme (IGBP) for understanding the global scale processes
controlling the time varying fluxes of carbon and associated biogenic
elements in the ocean and develop capability to predict the changes
in biogenic chemical processes due to climate change. The Indian
component ofv the JGOFS programme was launched in 1993 to estimate the
During the year, the observation part of the JGOFS programme was
completed and the data collected is being analysed to estimate the
carbon flux in the Arabian sea. Recognising the importance of JGOFS
studies,the Deaprtment is currently formulating a plan for undertaking
a similar study in the Bay of Bengal.
5.4.3 Land Ocean Interaction in the Coastal Zone (LOICZ)
During 9th Plan, the Department is proposing to implement one of the
core programmes of IGBP called Land Ocean Interaction in the Coastal
Zone (LOICZ) for understanding the changes in the coastal zones at
regional and global scale particularly due to global climate change.
The programme will determine carbon associated elemental fluxes which
are potential contributors to land-ocean interaction and improve
predicative capability of variability of the coastal zones of India
due to climate change. The potential coastal areas being considered
for study are Godavari Basin and Eastern Arabian Sea Margin.
The institutes associated with the programme are NIO, PRL, Andhra
University, Jawaharlal Nehru University(JNU), Anna University, etc.
