摘要
The problem of recognition of algal genera based on the remote sensing data requires the analysis of the algae biomass's distribution. This study provides the analysis of the algae spatial and temporal variations in the Peter the Great Bay. While 116 algal genera were observed, only a few genera have dominated. Usually, the dominant genus contributed about 60% of the sample's biomass (the minimal value is 20% usually) and 4 dominant genera contributed about 90% of the total phytoplankton biomass. The effective scattering crosssection of the algae in the samples is very changeable and this feature looks promising for the recognition problem. It was found that the spatial and temporal variations of the algal biomass are significant, but the percentage characteristics of a few dominant genera are relatively stable with no significant dependence on a region and a biomass value. The algae's composition analysis has demonstrated that the same algal genera are propagated in different parts of the Bay. For a given region and month, the set of algae dominated that constitutes about 90% of the monthly biomass is rather small (not more than 10 genera usually). Most of the alga genera similar to 75%) do not ever reach a mono domination state (more than 50% of the sample's biomass).
