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.
The data sampled at each station and each depth is formated to a ASCII file. Measured wavelengths (nm) and absorbance were recorded to a file. The information of filtration and measurement is written in 'fieldnote_particle.xls'.
