Light absorption and phytoplankton biomass in the Black Sea in spring 1995, supplement to: Churilova, T Ya (2001): Light absorption by phytoplankton and detritus in the Black Sea in spring. Translated from Okeanologiya, 2001, 41(5), 719-727, Oceanology, 41(5), 687-695


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.
