Seasonal variability of the primary production of ocean, its perennial trends can be efficiently estimated by satellite measurements of phytopigment dynamics. Complex spatial - temporary characteristics of currents in this area make investigation of biological processes in the Far Eastern Seas most difficult. CZCS data of 7.5 years were used to reveal spatial inhomogeneity in seasonal and perennial course of chlorophyll concentration IN THE Far Eastern Seas. Quasistationary areas with different types of variability and coherent areas of perennial trends of chlorophyll concentration have been found. The revealed zones are proposed for systematic monitoring of phytopigment concentration by space-borne and marine craft. The authors give hydrologic interpretation of the satellite data. Application of SeaWiFS data is discussed. Computer-animated dynamics and color maps are presented. The software available has been developed at the Institute of Biophysics SB RAS.

Note. Abstracts are published in author's edition
