Chlorophyll <em>a</em> and phaeopigment concentration varied in the layer studied from 0.1 to 1.8 mg·m<sup>−3</sup>, except for two stations with content reaching 2.2 and 4.4 mg·m<sup>−3</sup>. The relationship was revealed between light absorption coefficient by phytoplankton and chlorophyll <em>a</em> concentration at a wavelength, corresponding to spectrum maxima: a<sub>ph</sub>(438) = 0.044 × C<sub>a</sub><sup>1.2</sup>, <em>r<sup>2</sup></em> = 0.84 (<em>n</em> = 117); a<sub>ph</sub>(678) = 0.021 × C<sub>a</sub><sup>1.1</sup>, <em>r<sup>2</sup></em> = 0.89 (<em>n</em> = 117). Spectral distribution of light absorption coefficient by non-algal particles and colored dissolved organic matter was described by exponential function. Absorption parameterization coefficients were retrieved: (1) light absorption coefficient by non-algal particles (0.001–0.027 m<sup>−1</sup>) and by colored dissolved organic matter (0.016–0.19 m<sup>−1</sup>) at a wavelength of 438 nm; (2) spectral slope coefficients of these components (0.005–0.016 and 0.009–0.022 nm<sup>−1</sup>, respectively).</p>}, number={4}, journal={Marine Biological Journal}, author={Moiseeva, N.
