%X Harmful algal blooms have increased in recent years, and the building of early observing and monitoring system is very difficult. The authors indicated in this paper that, during the experimental time in the Pearl River Estuary, the variations of chlorophyll a and cell density were 0.9-31.1mg m-3 and 1.28×104-1.76×106cell L-1, respectively, and diatom was the dominant algal species. The diffuse attenuation coefficient, remotely sensed reflectance and fluorescence obtained by hyperspectral radiometers can be used to retrieve chlorophyll a and cell density, with relative root mean square error (RRMS) of chlorophyll a of 26.1%, 25.2% and 54.6%, and RRMS of cell density of 64.5%, 65.6% and 60.8%, respectively. Since the hyperspectal radiometers can obtain data at 1 hour interval, the moored optical buoy equipment with hyperspectral radiometers can be used for algal bloom observation and monitoring system.
