Abstract
The 500–800 nm spectra of replicata phytoplankton cultures freeze-dried upon glass fiber filters were determined both by photoacoustic spectroscopy (PAS) and by photoelectric absorption spectrophotometry. A number of the features of biological interest are better resolved in the PAS spectra. Further, PAS is sufficiently sensitive that it could be applied in the analysis of readily obtainable field samples.
