The purpose of this paper is to investigate the spectral responses of algal chlorophyll and water, under natural sunlight with varying suspended sediment concentrations (SSC). Twenty levels of SSC with each of two sediment types were generated, ranging from 50 to lOOOmgl-1, in 75101 of water containing chlorophyll-a concentrations of 718μgl-1 and 295 μl-1. Results indicate that suspended sediments do not eliminate the prominent spectral patterns of algal chlorophyll, even as SSC reached 1000mgl-1. Between 400 and 900 nm, the relation between reflectance and SSC satisfies the expression: d2R(λ)/dS2
