Introduction 



In the ocean ecological researches of today, the optical 

 methods find practical application alongside of traditional 

 biochemical methods. These new methods have undoubtedly 

 some advantages over the conventional ones. It is possible to 

 make measurements without disturbing the environment; there 

 is high spatial and time resolution and wide diversification of 

 the information received. The interaction of biological and 

 hy drophy sical factors gives rise to the formation of conservative 

 optical structures, dependent primarily on phytoplankton and 



their metabolites. As waters are carried by currents from 

 regions of formation, the biocenoses living therein undergo 

 gradual transformation, which is reflected in the optical 

 properties. Thus, if we identify those optical features that are 

 typical of water masses of different origin (or characteristic of 

 water mass in one or another stage of transformation), we shall 

 be able to identify ocean waters in terms of productivity and 

 other biological properties. The properties of light scattering 

 are dependent upon phytoplankton, which are extremely 

 susceptible to pollution. By determining the deviation of water 

 optical properties from natural level (in the regions that
