Interannual variation of chlorophyll-a concentration in the exclusive economic zone waters of Peninsular Malaysia

Chlorophyll-a concentration is one of the major indicators of phytoplankton production in the ocean. Identification of chlorophyll-a distribution and productivity is important to understand physical and biological processes in the ocean. The objectives of this study are to determine the spatial an...
