Modelling the influence of acclimation on the absorption properties of marine phytoplankton

An algorithm for calculating the marine phytoplankton total spectral absorption coefficient and its components for particular groups of photosynthetic and photoprotecting pigments has been developed. The input data for the calculations are the concentrations of these groups of pigments and depth in the sea. Over 1400 sets of simultaneously measured phytoplankton absorption properties and pigment contents at different depths in various water types were applied in the modelling. Photo- and chromatic acclimation as well as the package effect of pigments in cells and its variation in different waters have been considered. The vertical profiles of the product CI d are also described.
