内容 研究概要:Over the course of the last ten years, our laboratory has acquired a data base of about 800 absorption spectra of natural phytoplankton samples collected from several oceanic regions. These data have been analysed, along with concurrent information on pigment composition estimated using High Performance Liquid Chromatography (HPLC) techniques. The analysis highlights some general trends in the absorption characteristics and in pigment composition with changes in the phytoplankton biomass, as indexed by the concentration of the main pigment, chlorophyll-a. An empirical, three-parameter model can be used to estimate the absorption coefficient of phytoplankton at a given wavelength as a function of chlorophyll-a concentration. But such models fail to account for deviations in the absorption characteristics from the main trend. The implications for the estimation of both phytoplankton biomass and primary production from remotely-sensed data are examined.
