Light absorption and phytoplankton biomass in the Black Sea in spring 1995

DOI

Spectra of light absorption by suspended matter, phytoplankton, and detritus in the central and coastal parts of the Black Sea over the spring period (March-April 1995) were determined. Vertical homogeneity of the upper 40 m layer with respect to parameters in study was noted. Value of light absorption by phytoplankton normalized with respect to chlorophyll a was virtually independent of chlorophyll a concentration. A linear relationship between light absorption by phytoplankton and chlorophyll a concentration was established at the red spectral maximum. It is described by the equation y = 0.0153x; R**2 = 0.61. The average ratio of absorption values in the peaks was 2.29. Contribution of detritus to total light absorption at wavelength 440 nm was 23-62% regardless of depth and chlorophyll a concentration.
