摘要：Hyperspectral remote sensing reflectance was measured for a series of phytoplankton cultures as the first step in determining major taxon in an algal bloom by remote sensing.Two common bloom-forming species: Dinophyta, the dinoflagellate Prorocentrum minimum, and Cyanophyta, the cyanobacteria Synechococcus sp.were grown as mono cell cultures.Optical spectral measurements were taken from the cultures during logarithmic growth phases with progressive dilutions and culture mixtures.The primary objective of this study was to obtain base line reflectance spectra which can be used as references for remote sensing of algal blooms.Furthermore, the derivative analysis was applied to the reflectance spectra to explore the spectral features that can be used to identify phytoplankton taxon.Results showed that spectral reflectance correlated with phytoplankton biomass.Applying mathematical operators to the spectra of mono cell cultures corresponded to observed spectra of culture mixtures.Our results further corroborate previous findings that for some cases, remote sensing reflectance (Rrs) can be used to identify the primary taxon in algal blooms.
