Última Partitioning of the diffuse attenuation coefficient for photosynthetically available irradiance in a deep dendritic tropical lake Anais da ABC (AABC) BRANDÃO,LUCIANA P.M.; BRIGHENTI,LUDMILA S.; STAEHR,PETER A.; BARBOSA,FRANCISCO A.R.; BEZERRA-NETO,JOSÉ F.. ABSTRACT We studied the effects of particulate and dissolved optically active components on the attenuation of photosynthetic active radiation (PAR) in a tropical lake. The temporal and spatial distribution of tripton, Chl-a and aCDOM(440) and their relative contribution to the diffuse PAR attenuation coefficient (Kd) was investigated at 21 sites (dry and wet seasons and two intermediate periods) and at monthly interval at 1 pelagic site. Higher values of ​​ Kd were observed during the mixing period, characterized by a higher concentration of tripton and Chl-a compared to the stratified rainy season. In the spatial sampling PAR attenuation was dominated by tripton absorption/scattering (average relative contribution of 79%), followed by Chl-a (average...
