abstract = "Limnological variables along with inherent optical properties
provide substantial information about aquatic systems and are
crucial in development of bio-optical models. In the present work
we measured the inherent optical properties of a tropical
Brazilian reservoir (Tr{\^e}s Marias) simultaneously to the
concentration of optically active constituents such as
chlorophyll-a, total suspended solids and dissolved carbon in
order to characterize its bio-optical behavior. From June 17th to
22th 2013 twenty-two sampling stations were profiled using a 25cm
pathlength AC-S attenuation-absorption meter (WET Labs) and a
Hydroscat-6 backscattering meter (HOBILABS). Data set revealed a
division of reservoirs water body in two main water masses with
distinct biological and optical properties. Optically active
constituent concentration varied irregularly across the reservoir,
reaching 1.69-13.22 µgL^(-1) for chlorophyll-a, 1.6-11.93 mgL^(-1)
for total suspended sediments, 7.35-8.9 mgL^(-1) for dissolved
total carbon and 0.18-0.64\〖 m\〗^(-1) for CDOM
absorption in 443nm. Relationship between chlorophyll-a
concentration and the other constituents were low: 0.001 for total
suspended solids and 0.26 for total dissolved carbon.
Chlorophyll-a concentration showed a strong correlation with total
absorption in visible range with determination coefficient between
0.63 and 0.95. Phytoplankton was the dominant constituent in the
reservoir (followed by CDOM) and controlled the heterogeneity
observed in IOPs during sampling time.",
