Paper Abstract

THe seawater flurescence spectra were measured by laser induced fluorescence (LIF) method. ND:YAG laser with frquency-doubled output at 532 nm was used to induce the fluorescence. The laser fluorometer measured the fluorescence spectral distribution in the band from 540 nm to 740 nm. Chlorophyll-a concentration and conventional concentration of dissolved organic matter fluorescence (FDOM) in wavelength range from 560nm to 740nm wer calulated from LIF spectra. The correlation coefficient between chlorophyll-a and FDOM concentrations was calculated in the floating window along ship track. High value coefficient means that FDOM produced by phhytoplankton living on the investigation sea area at the given time interval. Chlorophyll-a-FDOM relationships were described by linear regression. Intercept coefficient is a background FDOM (or FDOM do not produced by phytoplankton living on the investigation sea area in given time interval) and the slope coefficient is FDOM productivity by one μg/l of chlorophyll-a of phytoplankton. The clusters were determined from calculated slope, intercept and correlation coefficients. The clusters correspond to phytoplankton communities and calculating coefficients characterize condition and the evloution stage of these phytoplakton communities.
