摘要

In-situ spectral reflectance of sea waters were acquired using a hand-held spectroradiometer during a series of sea-truth water sampling campaigns carried out in the Johore Strait, Singapore from Dec 1996 to Dec 1998. One field trip has also been carried out in Manila Bay, Philippines during an episode of harmful algal bloom in September 1998. The reflectance spectra were collected together with coincidental measurements of water quality parameters, such as the total suspended solid (TSS) and the chlorophyl-a (Chl-a) loadings. Phytoplankton cell counts and species identification were performed. Results of spectral analysis using the singular value decomposition technique show that, it is possible to distinguish different phytoplankton bloom types using the reflectance spectra.
