A method for detection of red tide by means of remote sensing reflectance peak shift is proposed together with suspended solid influence eliminations. Although remote sensing reflectance peak is situated at around 550nm for sea water without suffered from red tide, the peak is shifted to the longer wavelength when sea water is suffered from red tide. Based on this fact, it is capable to detect red tide using high wavelength resolution of spectroradiometers. The proposed system uses green color filtered cameras. Acquired imagery data can be transmitted through wireless LAN to Internet terminal and can be archived in server through Internet. This is the proposed ground based red tide monitoring system. The paper also proposes a method for removing suspended solid influence on red tide suffered area estimations. The proposed method and system is validated in laboratory and field experiments. The system is deployed at coastal areas of Ariake Sea in Kyushu, Japan.
