Estimation of chlorophyll-a concentration from optimizing a semi-analytical algorithm in productive inland waters
(2018-02-01)
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due to higher residence time compared to rivers. The monitoring of ...
An assessment of semi-analytical models based on the absorption coefficient in retrieving the chlorophyll-a concentration from a reservoir
(Elsevier B.V., 2019-04-01)
Monitoring chlorophyll-a (Chl-a) concentrations in inland waters is crucial for water quality management, since Chl-a is a proxy for phytoplankton biomass and, thus, for ecological health of a water environment. Chl-a ...
Glint removal assessment to estimate the remote sensing reflectance in inland waters withwidely differing optical Properties
(2018-10-01)
The quality control of remote sensing reflectance (Rrs) is a challenging task in remote sensing applications, mainly in the retrieval of accurate in situ measurements carried out in optically complex aquatic systems. One ...

BRAZILIAN INLAND WATER BIO-OPTICAL DATASET TO SUPPORT CARBON BUDGET STUDIES IN RESERVOIRS AS WELL AS ANTHROPOGENIC IMPACTS IN AMAZON FLOODPLAIN LAKES: PRELIMINARY RESULTS
(Copernicus Gesellschaft Mbh, 2015-01-01)
This work presents ongoing efforts and preliminary results for building a dataset that represents the first and most comprehensive bio-optical information available on Brazilian inland waters to support the development of ...
Performance of existing QAAs in Secchi disk depth retrieval in phytoplankton and dissolved organic matter dominated inland waters
(Spie-soc Photo-optical Instrumentation Engineers, 2018-09-12)
A semianalytical model developed to estimate the Secchi disk depth (Z(SD)) was used in eutrophic-to-hypereutrophic reservoirs (Ibitinga, Ibi, and Barra Bonita, BB) placed in the cascade system of the Tiete River, Brazil. ...
Evaluation of the suitability of MODIS, OLCI and OLI for mapping the distribution of total suspended matter in the Barra Bonita Reservoir (Tietê River, Brazil)
(2016-10-01)
The objective of this work was to evaluate the suitability of three remote sensors, namely, the Moderate Resolution Imaging Spectroradiometer (MODIS), the Operational Land Imager (OLI), and the Ocean Land Color Instrument ...
Nariva Ferry
(Unknown, 2011-03-01)
The postcard shows a wooden punt which served as a ferry bridge over the Nariva and Ortoire rivers (1870s - 1950s) as there was no road to the district of Mayaro. The trip across the river used to cost a penny. People, ...
