This study is focused on bio-optical data collected from deep parts of the eastern and western Black Sea and the Crimean shelf waters during nineteen cruises of RV “Professor Vodyanitsky” carried out in different seasons in 2015–2022. Based on a long-term data set, a parameterization of light absorption by phytoplankton (aphλ), non-algal particles (aNAPλ), and colored dissolved organic matter aCDOMλ was performed. Parameterization coefficients for phytoplankton absorption were revealed for all seasons. A two-fold difference was observed in the chlorophyll “a” specific light absorption coefficient of phytoplankton in the Black Sea between summer and winter seasons. The difference was related to the “pigment package effect” resulting in the self-shading of pigments caused by changes in intracellular pigment concentration and phytoplankton cell size due to adaptation of phytoplankton to the varying environmental factors. The use of seasonal-specific coefficients of parameterization of phytoplankton light absorption provides more accurate retrievals of aphλ spectra based on the chlorophyll “a” concentration in modelling the light field and primary production using a spectral approach...
