Landsat-based remote sensing of the colored dissolved organic matter absorption coefficient in a tropical oligotrophic reservoir
(2018-01-01)
Colored dissolved organic matter (CDOM) is a photoactive fraction of organic carbon that can be detected via remotely sensed data (proximal and satellite). The retrieval of the absorption coefficient of CDOM (aCDOM) in ...
Diatoms from lentic and lotic systems in Antioquia, Chocó and Santander Departments in Colombia
(Universidad de Costa Rica, 2008)
Brachysira aristidesii sp. nov. (Bacillariophyceae, Brachysiraceae): a new species from oligotrophic and mesotrophic tropical reservoirs in southeastern Brazil
(Magnolia Press, 2020-08-19)
A new diatom species, Brachysira aristidesii sp. nov., is described from three oligotrophic and mesotrophic reservoirs in Piracicaba River basin, State of Sao Paulo, Brazil. Descriptions are based on light and scanning ...
Multisource data for seasonal variability analysis of cyanobacteria in a tropical inland aquatic environment
(Csiro Publishing, 2017-01-01)
Cyanobacterial blooms are related to eutrophic conditions that compromise the many uses of reservoirs. Thus, quick and effective methods for detecting the abundance of cyanobacteria in waterbodies are needed to complement ...
An investigation into the particle volume scattering function variability in a cascading reservoir system
(Springer, 2016-06-01)
This work analyzed the spectral and spatial distribution of the particle volume scattering function, beta(p), in a cascading reservoir system. During fieldworks water quality parameters and scattering data were sampled in ...
Retrieval of Secchi disk depth from a reservoir using a semi-analytical scheme
(2017-09-01)
The mechanistic model reported in Lee et al. (2015) estimating the Secchi disk depth (ZSD) was applied to an oligo- to mesotrophic reservoir in Brazil. The model was originally validated with data covering lake, oceanic, ...
Estimating the CDOM absorption coefficient in tropical inland waters using OLI/Landsat-8 images
(2016-07-02)
Coloured dissolved organic matter (CDOM) is the most abundant dissolved organic matter (DOM) in many natural waters and can affect the water quality, such as the light penetration and the thermal properties of water system. ...
Facies model of a sedimentary record for a Pantanal‐like inland wetland
(Wiley Blackwell Publishing, Inc, 2020-06)
Despite recent advances in wetland studies, ancient wetland deposits are still not well documented, and their facies characteristics are poorly registered. Sedimentary facies and sequence stratigraphic analysis of the ...
Parametrization and calibration of a quasi-analytical algorithm for tropical eutrophic waters
(Elsevier B.V., 2016-11-01)
Quasi-analytical algorithm (QAA) was designed to derive the inherent optical properties (IOPs) of water bodies from above-surface remote sensing reflectance (R-rs). Several variants of QAA have been developed for environments ...
