Since the launch of CZCS in the late seventies, satellite-derived Chlorophyll (Chl) has been used for several decades as the primary proxy for phytoplankton biomass. Due to the limited number of spectral bands, satellite products were derived from empirical spectral band ratios. The reliability of the satellite retrievals is questionable when dealing with coastal waters where other optically active substances, such as suspended sediment and organic matter, affect the reflectance spectrum [ 15 ]. The MEdium Resolution Imaging Spectrometer (MERIS), from the second generation of ocean color sensors, offers a much larger number of spectral bands, thus allowing various water quality products to be derived for both coastal and open ocean waters [ 16 – 22 ]. The combined analysis of multiple satellite products for the study of phytoplankton blooms allows for a more accurate description of the event and its causative environmental factors [ 23 – 26 ]. MERIS has provided satellite ocean color imagery between April 2002 and April 2012, and with 15 spectral bands this sensor is well suited for water quality monitoring in coastal waters [ 27 ]. For this study, four MERIS products, namely Chlorophyll (Chl) and Fluorescence Line Height (FLH), Maximum Chlorophyll Index (MCI) and Total Suspended Matter (TSM), were chosen as indicators of phytoplankton biomass, phytoplankton surface expressions and river discharges (or bottom resuspension) to assess phytoplankton bloom dynamics in the waters of the GBRW and the VDG ( Figures 1 and 2 ). This study aims at demonstrating that the combined analysis of four ocean color products over the full mission of a single sensor can be used to unravel the dynamics of phytoplankton in a coastal region. Specifically, the objectives of this research are to qualitatively analyze the temporal and spatial patterns of phytoplankton blooms in selected clusters of the GBRW and the VDG.
