This work was to establish an
infrastructure for receiving, storing, processing and sharing
of information produced by the scientific task groups. The
volume of data input was very large. As PREPP is a
multi-disciplinary project, the data inputs varied greatly in
format, frequency and medium, which was a challenge for the
task of data management and ultimately also for other
researchers wishing to access the data sets, and for use by
the wider public.
The following picture provides an overview
of the data system infrastructure developed for PREPP:
The data system stores the data input from various
- Satellite data set from HKUST's Satellite
- Shore-based stations such as CODAR, YSI
and AWS data.
- Ocean optical data from Port Shelter
using PRR 800 Cary 100.
- Cruise data.
- Numerical model data output.
Data acquisition requires various
telecommunication means such dedicated telephone lines, mobile
data transmissions and high speed networks to send data to the
data server (Oracle). The data system is connected to various
communication network and handles the real-time data input
After the data are saved in the Oracle
server, they can then be disseminated in to ways: (1) through
the Intranet to PREPP and other authorized users during the
project period; (2) through the Internet to interested
scientists and the public free of charge. The web site
developed for the public is a gateway for scientists or other
users who are interested in obtaining more information about
the coastal environment of the Pearl River Estuary, including
data resources, enquires and searching capabilities.
