Abstract:

The statistical analysis of data on chlorophylls a, b, c and carotenoids k content in different water layers was carried out in monitoring conditions in a number of points of Lake Teletskoye. The distribution of concentrations within the number of samples has the lognormal character that makes it possible to use the geometrical mean concentrations in models. The surface layer showed the stable decrease of pigments content in k-a-c-b order in all sampling points and the lack of concentration increase in the "south-north" direction. Vertical decrease of pigments from surface to 50 m layer is exponential, and their decrease in deeper layers is insignificant. The approximation formulas of the depth dependence of chlorophylls and carotenoids concentration were derived. These formulas are easy-to-use for further calculation of coefficicents of light absorption by phytoplankton.
