| Quantitative microphytoplankton samples were collected from shallow-water coastal stations in Channel between 1976 and 1980. The aim of the study is to describe the seasonal succession of the populations with respect to some physico-chemical parameters, i. e. to relatate the distribution of abundance to hydrographic seasons. We build a contigency table (species x environmental variables, both under disjunctive coding), which is described by correspondence analysis (reciprocal averaging). The results show the main features of the annual changes in the community dominated by diatoms |
