Abstract:
This study was conducted in order to estimate and characterize the CDOM in the coastal
water of Kuala Terengganu based on the understanding of light properties. This study
dealth with the basic concept of remote sensing that can help in developing the remote
sensing algorithms for seawater constituent estimation. Sampling was carried out at 24
rd
stations on 23
th
October 2007 to 27
October 2007. In this study, AOP radiometric
parameters such as upwelling i1rndiance and diffuse attenuation coefficient (Kd) were
measured during field measurements. The highest CDOM absorption was found at
nearshore stations and the lowest CDOM absorption at offshore station is ranged between
1
0.00 I 6m-
to 0.64m-
1
• Results demonstrated that CDOM cannot be estimated accurately
using the Kd. All wavelengths were found to have poor relationship with CDOM. The
highest polynomial regression coefficient (R
2
) was only 0.65 at wavelength 650nm. The
results demonstrated the difficulty in estimating the CDOM concentration using the
optical properties at the coastal water of Kuala Terengganu.
