Reservoirs are artificial environments built by humans, and the impacts of these not completely known. Retention time high nutrient availability in water increases eutrophic level. Eutrophication is directly correlated to primary productivity phytoplankton. These organisms have an important role environment. However, concentrations determined species can lead public health problems. Species cyanobacteria produce toxins that cause serious diseases liver nervous system, which could death....
In this present research, we assessed the performance of band algorithms in estimating chlorophyll-a (Chl-a) concentration based on bands two new sensors: Operational Land Imager onboard Landsat-8 satellite (OLI/Landsat-8), and MultiSpectral Instrument Sentinel-2A (MSI/Sentinel-2A). Band combinations designed for Thematic Mapper Landsat-5 (TM/Landsat-5) MEdium Resolution Imaging Spectrometer Envisat platform (MERIS/Envisat) were adapted OLI/Landsat-8 MSI/Sentinel-2A bands. Algorithms...
The Cerrado domain, one of the richest on Earth, is among most threatened in South America due to human activities, resulting biodiversity loss, altered fire dynamics, water pollution, and other environmental impacts. Monitoring this domain crucial for preserving its ecosystem services. This study aimed apply machine learning techniques classify main vegetation formations within IBGE Ecological Reserve, a protected area Brazil, using high-resolution PlanetScope imagery from 2021 2024. Three...
Coloured dissolved organic matter (CDOM) is the most abundant (DOM) in many natural waters and can affect water quality, such as light penetration thermal properties of system. So objective this letter was to estimate CDOM absorption coefficient at 440 nm, aCDOM(440), Barra Bonita Reservoir (São Paulo State, Brazil) using operational land imager (OLI)/Landsat-8 images. For two field campaigns were conducted May October 2014. During remote sensing reflectance (Rrs) measured a TriOS...
As of 16 May 2020, the number confirmed cases and deaths in Brazil due to COVID-19 hit 233,142 15,633, respectively, making country one most affected by pandemic. The State São Paulo (SSP) hosts largest Brazil, with over 60,000 date. Here we investigate spatial distribution spreading patterns SSP mapping autocorrelation clustering virus relation population density hospital beds. Clustering analysis indicated that City is a significant hotspot for both deaths, whereas other cities across...
In this article, a possible phytoplankton package effect on the chlorophyll-a specific absorption coefficient (a*phy) is investigated. Two fieldworks were conducted in May and October 2014 Barra Bonita (BB) reservoir. During fieldworks, radiometric water samples obtained. From data, remote sensing reflectance (Rrs) calculated from (chl-a) concentration, (aphy) a*phy The results show that for first fieldwork (in May), was less perceived than second October). May, more pronounced highest chl-a...
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due higher residence time compared rivers. monitoring of is important prevent risk contamination by toxins reservoirs used for drinking water supply. In this context, a physical model-based approach was adopted retrieve chlorophyll-a (chl a) concentration, photosynthetic pigment found all phytoplankton species. We assumed that...
O uso do sensoriamento remoto voltado para a determinação de amostras campo é grande valia estudos ambientais, uma vez que as imagens satélite apresentam atributos capazes avaliar variabilidade espectral da superfície água considerando área extensa. Desse modo, abordagem deste trabalho objetiva definir um método seleção estratificada baseada na no espectro visível e infravermelho oriundos sensor Landsat-8/OLI. conta com utilização dados raster representam o desvio padrão série temporal...
In this study, a data set of total suspended matter (TSM), chlorophyll-a (Chl-a), backscattering coefficient (bb) and the remote sensing reflectance (Rrs) were measured in euphotic zone two hydroelectric reservoirs at 71 stations during field surveys wet dry seasons. These are located cascading system Tietê River, São Paulo State, Brazil. The limnological optical interpolated using ordinary kriging technique to map their spatial distribution. differences TSM, Chl-a bb space time...
The quality control of remote sensing reflectance (Rrs) is a challenging task in applications, mainly the retrieval accurate situ measurements carried out optically complex aquatic systems. One main challenges related to glint effect into measurements. Our study evaluates four different methods reduce from Rrs spectra collected cascade reservoirs with widely differing optical properties. first (i) method adopts constant coefficient for skylight correction (ρ) any geometry viewing and wind...
