Abstract:
The concentration of net primary productivity (NPP) along Kuala Terengganu coastal
water depends on physical parameters, season and satellite images. The concentration
of NPP also plays an important role in represents the total flux of organic carbon that
an ecosystem can utilize for all other metabolic processes. This study aims is to get
the in-situ concentration of NPP, to determine the NPP monthly using satellite
imagery, to determine the correlation between in-situ and satellite imagery value and
to determine the difference ofNPP during different season (South West monsoon and
Inter monsoon). The sampling was conducted on 12 to 15 May, 2010 and 30 to 2
October, 2010. The result shows that the in-situ concentration of net primary
productivity by using light intensity for first sampling was around 283.19 to 521.29
mgC/m
3
/day while for MODIS image value was around 261.26 to 670.12
mgC/m
3
/day. For second sampling, the in-situ concentration ofNPP was range around
34.77 to 457.83 mgC/m
3
/day while for MODIS image value was around 272.07 to
535.11 mgC/m
3
/day. Then, for NPP concentration monthly by using satellite imagery
shows that year 2005 and 2008, month of December shows the highest value ofNJ>P,
while for 2006, 2007, 2009 and 2010 showed that January had the highest value of
NPP among the others month.
