The Pearl River Estuary and its coastal waters, including its hydrodynamic circulations, sediment transport and chemical and biological ecosystem, are very complex dynamic system.  To understand the behavior of such a system, one needs to have a long-term and serial observed data on all the physical, chemical and biological parts of the system.  Such in situ investigations are very costly to carry out.  Available data from previous investigations are sparse, and several data sets were not available to us because of existing restrictions on sharing of information.  Therefore the project has fulfilled its mission using the following approaches:

  1. Remote sensing surveys through satellite receiving stations for studies on surface sea temperature, suspended sediments and chlorophyll 'a'.  This allows low-cost and geographically wide coverage, but its use is limited in this region because of frequent cloud cover.

  2. Numerical modeling for simulation of the behavior of complex systems such as estuaries.  This allows us to fill in data gaps in the observational record of infrequent and geographically limited data.

  3. In situ measurements such as shored base data acquisition and shipboard measurement to obtain ground truth.

  4. A data infrastructure provides an integrated platform for data acquisition, storage and archival so that scientist can analyze and compare data for their research.

The following sections describe the specific activities, instruments, methodologies that the project teams deploy to achieve it objective:
