Abstract—This paper demonstrates the effectiveness of the use of the cross-correlation Shannon entropy; the cross-correlation Shannon entropy is a generalization of spectral entropy, which is widely used in scientific research, as a method of analysis of mutual correlations between plankton abundance fluctuations and temperature variations. In particular, analysis of time series that characterize the dynamics of zooplankton, phytoplankton, and bacterioplankton and water temperature variations shows that mutual correlations are most significant between temperature and bacterioplankton.
