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