  abstract = {{T}he composition of phytoplankton and the concentration of pigments in their cells make their absorption and specific absorption coefficients key parameters for bio-optical modeling. {T}his study investigated whether the multispectral vertical diffuse attenuation coefficient of downward irradiance ({K}-d) gradients could be a good framework for accessing phytoplankton genera. {I}n situ measurements of remote sensing reflectance ({R}-rs), obtained in an {A}mazon {F}loodplain {L}ake ({L}ago {G}rande do {C}uruai), were used to invert {K}-d, focusing on {S}entinel-3/{O}cean and {L}and {C}olor {I}nstrument ({OLCI}) sensor bands. {A}fter that, an analysis based on the organization of three-way tables ({STATICO}) was applied to evaluate the relationships between phytoplankton genera and {K}-d at different {OLCI} bands. {O}ur results indicate that phytoplankton genera are organized according to their ability to use light intensity and different spectral ranges of visible light (400 to 700 nm). {A}s the light availability changes seasonally, the structure of phytoplankton changes as well. {S}ome genera, such as {M}icrocystis, are adapted to low light intensity at 550-650 nm, therefore high values of {K}-d in this range would indicate the dominance of {M}icrocysts. {O}ther genera, such as {A}ulacoseira, are highly adapted to harvesting blue-green light with higher intensity and probably grow in lakes with lower concentrations of colored dissolved organic matter that highly absorbs blue light (405-498). {T}hese findings are an important step to describing phytoplankton communities using orbital data in tropical freshwater floodplains. {F}urthermore, this approach can be used with biodiversity indexes to access phytoplankton diversity in these environments.},
