Abstract This research investigated the spatial and temporal distributions of Trichodesmium spp. and Richelia intracellularis in the South China Sea. The surveys covered the period from July 2000 to July 2002. A total of eight cruises, including spring, summer and fall were conducted. The sampling stations located between 18~22o N and 115~122 o E , over the continental shelf, the slope, and the basin of the northern South China Sea. Trichodesmium biomass was higher in summer and fall than spring. There was no significant difference in biomass among shelf , slope and basin. The averaged biomass was 69
