Estimation of the spectral absorption coefficients of phytoplankton in the sea
A modified opal-glass technique was developed for the determination of the specific absorption spectrum of natural phytoplankton. Glass fiber filters were used to collect suspended particles. The absorption spectrum was determined before and after the extraction of pigments by methanol. This technique was evaluated using phytoplankton cultures and seawater samples containing various kinds of particles other than phytoplankton cells. Specific absorption coefficients of phytoplankton (kc) were estimated from the spectrum of the modified opal-glass technique where the specific absorption coefficients determined directly in the original suspension were applied for correction. Averaged specific absorption coefficients (kc) were also derived.
