Based on the data measured during an algal culture experiment in July 2011, this paper analyzed absorption characteristics of alga Amphidinium careraeHulburt in growth and decay periods. The results showed that in 21 days of the algal culture the growth period started from the 1st to the 15th day, and then the alga entered into the decay period. Meanwhile, the total absorption spectra varied notably: the absorption peak of phytoplankton was not found in the blue band (440nm), but was obvious in the red band (675nm). Diurnal variation of absorption coefficient in the decay period was more significant than that in the growth period. Besides, the total absorption coefficient and the chlorophyll concentration displayed a consistent tendency. Moreover, the inter-band relationship of the total absorption coefficient at 675 nm with other bands was quite remarkable; but in different periods, the fitted curves showed significant differences for the same band; and the curves in the decay period were above those in the growth period. Overall, both curves became closer and closer with increasing wavelength, and were almost overlapped at 667 and 678nm. For some specific bands (440 and 675nm), high correlations of power function between total absorption coefficient and chlorophyll concentration were found (the coefficients of determination surpassed 0.98), and the fitted curves were related to algal growth stage.
