Satellite-Retrieved Surface Chlorophyll Concentration Variation Based on Statistical Methods in the Bohai Sea
Data of chlorophyll concentration in the Bohai Sea is obtained by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) from 1998 to 2009. Empirical Orthogonal Function (EOF) is used to analyze the spatialtemporal variation of chlorophyll concentration in the Bohai Sea. Discrete power spectral density (PSD) is used to calculate variation periods of the first four modes of EOF. All the processes are used IDL language. The results show that spatial distribution of chlorophyll concentration is characterized by decreasing from coastal shore to off shore. The seasonal variations show lowest concentration is in summer. The first four explain 22%, 11%,4% and 3% variation, respectively.
