Abstract

We present some results of our investigations of the concentrations of pigments and the biooptical characteristics of suspended and dissolved organic substances in the coastal region of the sea near the coast of the Crimea. Under the conditions of variable meteorological situation, we observe well-pronounced variations of the concentrations of pigments in the surface layer and their different vertical profiles. The inhomogeneity of the distribution of pigments in depth is accompanied by a decrease in the specific coefficients of absorption of light by phytoplankton. In the analyzed case, the contribution of “detritus” to absorption does not vary with depth and its maximum values are observed under the storm conditions. The dependences of the absorption of light by phytoplankton and suspended substances on the content of pigments and of the absorption of light by dissolved organic substances on the wavelength are established. These dependences are well described by power and exponential functions.
