Spectral absorbance of particles inside the visible range (350 - 750 nm). Absorbance of suspended particles, including phytoplankton cels and detritus, collected on a glass fiber filter were measured using spectrophotometer. Phytoplankton pigment on filter was extracted using methanol between 24 and 48 hours, and the absorbance of detritus was measured.
