STUDY ON OCEAN COLOR ENVIRONMENT OF CHINA COAST BY SATELLITE REMOTE SENSING
卫星遥感监测我国沿海水色环境的研究

Studying the variety of features and scales of ocean color distribution, which is basically decided by chlorophyll, suspended material and yellow staff, in Chinesecoast area is very difficult because of complehng temporal and spatial requirements.Measurements from satellite had demonstrated that space sensor can be applied to use satellite to measure the ocean color to understand oceanic, biological and physicalprocess. In 1978, the CZCS mission had provided the first observation of ocean colorfrom space (NASA, 1983; Pan, 1987). Following, the satellites of FY-1A and FY-1B(China in 1987 and 1989 respectively), ADEOS (Japan, in 1996) and SeaWiFS (U.S.A., in 1997) has brought a welcomed and improved renewal to ocean color satellitedata. In 1999, there are three Asian satellites with ocean color sensor which weresuccessfully launched. They are FY-1C (China, in May), ROCSAT-1 (Taiwan of China,in Feb.) and KOMPSAT-1 (Korea). Those satellites have being provided very goodocean color data for the Asian area research. In the coming new century, the veryhigh spectra resolution ocean color sensors are going to be launched and going tobring more advanced data for coast water monitoring. The Chinese ocean color remote sensing applicahon system has been developed bySecond Inshtute of Oceanography, SOA, locuted at Hangzhou, in 1997. The systemincludes the data receiving, processing, distribution, calibration / validation andapplication. The Hangzhou station of SIO, SOA has capability to received the FY-1and AVHRR data since 1989. It is also a SeaWiFS scientific research stationauthorized by NASA U. S. A., to free receive SeaWiFS data since September 16,1997. The ocean color remote sensing data have been applied in monitoring coastalwater color environment such as the spatial distribution of chlorophyll, suspendedmaterial concentration, red tide detection and coastal current study. The results showthat the ocean color remote sensing has the latent capacity in the detection of coastalwater environment.
