Spatial and temporal variations of the inherent optical properties in a tropical cascading reservoir system
(Springer, 2016-06-01)
In order to verify the effect of a cascade system in the water quality of two tropical reservoirs in Brazil, this work proposed to make use of the inherent optical properties (IOPs) as well as the specific inherent optical ...
Retrieval of Suspended Particulate Matter in Inland Waters with Widely Differing Optical Properties Using a Semi-Analytical Scheme
(Mdpi, 2019-10-01)
Suspended particulate matter (SPM) directly affects the underwater light field and, as a consequence, changes the water clarity and can reduce the primary production. Remote sensing-based bio-optical modeling can provide ...
Inherent optical properties in the Gulf of California
(Ciencias Marinas, 1999)
In order to be able to invert optical remote sensing data, it is necessary to understand the absorption, scattering and attenuation spectra. In this paper we present a study of the vertical distribution and spectra of the ...
Estimating the optical properties of inorganic matter-dominated oligo-to-mesotrophic inland waters
(2018-04-09)
Many studies over the years have focused on bio-optical modeling of inland waters to monitor water quality. However, those studies have been conducted mainly in eutrophic and hyper-eutrophic environments dominated by ...
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 ...
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 ...
Phytoplankton dynamics based on satellite inherent optical properties and oceanographic conditions in a patagonian gulf frontal system in relation to the adjacent continental shelf waters
(Elsevier, 2021-11)
The dynamics of phytoplankton across a seasonal frontal system formed in San José Gulf (SJG, Patagonia Argentina) and in neighbouring shelf waters was assessed based on bio-optical satellite data (2003–2018) and spring and ...
Re-parameterization of a quasi-analytical algorithm for colored dissolved organic matter dominant inland waters
(Elsevier B.V., 2016-12-01)
Quasi-Analytical Algorithms (QAAs) are based on radiative transfer equations and have been used to derive inherent optical properties (IOPs) from the above surface remote sensing reflectance (R-rs) in aquatic systems in ...
Assessment of quasi-analytical algorithm for estimating the inherent optical properties in a complex cascade system
(Spie-soc Photo-optical Instrumentation Engineers, 2018-09-04)
Several quasi-analytical algorithm (QAA) versions were developed to make it suitable for different inland water systems. QAA(BBHR) and QAA(OMW) were reparameterized based on two reservoirs from the Tiete River cascading ...
Detecção da dinâmica de comunidade fitoplanctônica a partir do coeficiente de absorção específico da clorofila em águas interiores produtivas
(2017-01-01)
Aim: In this research, we investigated the spectral variability of the specific phytoplankton absorption coefficient, a* φ, measured in a tropical meso-to-hypertrophic reservoir, aiming to find spectral features associated ...
