Monitoring phytoplankton classes and their abundance is a routine task in marine ecology research. With the frequent occurrences of red tide, there is an urgent need for rapid analysis methods that can provide quatitative informations. Three dimensional fluorescence spectrum, also termed as excitation-emission matrix(EEM) spectrum, gives total fingerprints informations in the whole range of wavelenghths. By using chemomatrics on extracting their pigments spectral features, EEM spectrum is often...
