Abstract

Abstract

The remote sensing reflectance spectra measured from 17 phytoplankton species belonging to dinophyta and bacillariophyta were studied. The fourth-derivative analysis was performed on the spectra after being smoothed,reversed and normalized. According to clustering analysis, the algae were classified correctly into the two catagories. The derivative spectra of dinophyta and bacillariophyta were separately averaged to obtain their characteristic spectra. And a sensitivity analysis about mineral particles was carried out, and the correct probability could up to 90% when the mineral concentration was less than 50 mg/dm³ .In a word, the derivative method could be a useful tool to differentiate dinophyta and bacillariophyta.
