Abstract:
The field of remote sensing can be used to determine the distribution of different types
of constituents in seawater such as chlorophyll-a, Coloured Dissolved Organic Matter
(CDOM) and Total Suspended Sediments (TSS). In this research, the measurements of
Apparent Optical Properties (AOP) parameters such as Rrs and Kd have been conducted
and their relationship with TSS were investigated. 22 stations along Kuala Terengganu
coastal waters were chosen as the sites of study. The in-situ observations were carried
out between 14th and 17th of September 2006. The in-situ data of radiometric
measurements (EJ...01 and Lu(Ol) were processed using the Prosoft 7.78 software to
derive AOP parameters (Rrs and Kd. For each station, water samples were collected to
measure the concentration of TSS. The regression analyses were done between the
concentration of TSS and AOP parameters in order to determine the relationship
between them. The regression analysis revealed that the TSS can be best estimated at
675 nm wavelength of Rrs and 532 nm wavelength of Kd. Results obtained suggest that
in-situ measurement of AOP parameters are potentially valuable to develop site-specific
algorithms for estimating TSS concentration through remotely sensed optical data.
