Abstract:
The study of the apparent optical properties and its relationship with chlorophyll-a were
conducted in coastal water of Kuala Terengganu. This study was carried-out in order to
estimate the the chlorophyll concentration from in situ spectral signature (Rrs and water
leaving radiance, Lwn) around Kuala Terengganu coastal waters. Twenty eight stations are
visited. The ground sampling was conducted from 23 October 2007 until 27 October
2007. In this study, AOP radiometric parameter such as upwelling radiance, remote
sensing reflectance and water leaving radiance have been measured during in situ.
Highest concentration of chlorophyll-a was observed in the study area was 0.4741 mg/m
3
at station 28. The study found that chlorophyll-a can be estimated using the Rrs at 673nm
wavelength through polynomial relationship with regression 0.7333 while study also
revealed that chlorophyll-a can be estimated using the Lwn at 656nm wavelength
through polynomial relationship with regression 0.6264.
