             abstract = "The chlorophyll-a specific absorption coefficient (aphy*) is used 
                         to describe phytoplankton light absorption capability per unit of 
                         chlorophyll-a (chl-a). This coefficient has an important role in 
                         remote estimate of chl-a concentration and primary productivity, 
                         because when treated as a constant it can be a significant source 
                         of uncertainty in these models. aphy * (\λ) could vary both 
                         seasonally and spatially, because it is dependent on the 
                         physiology and ecology of phytoplankton communities, which vary 
                         with external factors such as turbulence induced in the water 
                         column by the increase of discharge peaks in reservoirs. The aim 
                         of this study is to analyze the spatial-seasonal variability of 
                         aphy* (\λ) in Ibitinga/SP Reservoir, in order to better 
                         understand the dynamic of light absorption by phytoplankton in 
                         optically complex waters. The methodology is based on laboratory 
                         remote sensing for measuring the phytoplankton absorption 
                         coefficient (aphy (\λ)) by means of a spectrophotometer 
                         according to Tassan and Ferrari (2002) method. The aphy* 
                         (\λ) was obtained dividing aphy (\λ) by chl-a 
                         concentration determined according to Nush (1980). The highest 
                         amplitude chl-a concentration, for the period of field campaigns, 
                         occurred in the months of February and September. Analyzing the 
                         aph* (\λ), it was noted that the spectrum had a higher 
                         variability in magnitude than in shape, especially in the blue and 
                         red region, both spatially as seasonally.",
