摘要：

Spatial-temporal variation of Chlorophyll-a concentration retrieved by Moderate Resolution Imaging Spectroradiometer (MODIS-Auqa, aboard Auqa satellite) was analyzed since the starting MODIS-Auqa mission in July 2002 till July 2009 in Bohai Sea. Statistical methods including anomaly, sliding average, power spectral density were used to analyze the spatial-temporal variation of Chlorophyll-a concentration. The results showed that seasonal variation of Chlorophyll-a concentration represented the maximum values in February-March, the minimum values in July. Monthly anomalies showed about 2-year cycle. Spatial variation showed high concentration in coastal shore and decreased slowly to offshore. The whole Bohai Sea showed high Chlorophyll-a concentration in the year 2006.
