Variability of light absorption coefficients by different size fractions of suspensions in the southern Baltic Sea
The average chlorophyll-specific and mass-specific light absorption coefficients, i.e., light absorption coefficients normalized to Chl a or SPM, were determined for all size fractions. The chlorophyll-specific coefficients ap(Chla)(λ), ad(Chla)(λ) and aph(Chla)(λ), ± standard deviations, do not...

Zusammenfassung: | The average chlorophyll-specific and mass-specific light absorption coefficients, i.e., light absorption coefficients normalized to Chl a or SPM, were determined for all size fractions. The chlorophyll-specific coefficients ap(Chla)(λ), ad(Chla)(λ) and aph(Chla)(λ), ± standard deviations, do not allow clear separation of the individual fractions. For mass-specific coefficients, ap(SPM)(λ), ad(SPM)(λ) and aph(SPM)(λ), it is possible to distinguish between large particles (20-200 µm) and small and medium particles (0.2-20 µm). These results will allow monitoring of suspended matter in size classes in optically complex waters of southern Baltic Sea. |
