The four seasonal marine microbial association communities are detected by s-NMF. The results show that the association community pattern diversity of winter is more than that of spring, summer and fall, which indicates that the seasonal variability might have the greatest influence on the marine microbe diversity. We also find that some environmental factors are strongly associated with some microbes, and there are different association structures in four seasons. Some typical communities are discussed in this paper, and the analysis results of other communities in four season microbial networks are shown with the Supplementary Material.
