Monitoring water quality parameters and their ecological effects in transitional waters is usually performed through situ sampling programs. These are expensive time-consuming, often do not represent the total area of interest. Remote sensing techniques offer enormous advantages by providing cost-effective systematic observations a large system. This study evaluates potential monitoring using S...

Aquaculture of the eastern oyster, Crassostrea virginica , is an expanding industry in US, particularly Gulf Maine. High resolution ocean color satellites launched last decade potentially provide aquaculture-relevant water-quality parameters at farm scales. However, these parameters, such as temperature, suspended particulate matter (SPM), and Chlorophyll a (Chl a), need to be derived by intere...

In San Francisco Bay (SFB), light availability is largely determined by the concentration of suspended particulate matter (SPM) in water column. SPM exhibits substantial variation with time, depth, and location. To study how influences phytoplankton growth, we coupled a sediment transport model hydrodynamic biogeochemical model. The models were used to simulate conditions for year 2011 focus on...

Fluvial suspended particulate matter (SPM) fluxes transport large amounts of contaminants that can affect water quality and river ecosystems. To better manage these inputs in systems, it is essential to identify SPM sediment sources. Many studies have applied a fingerprinting method based on using metals integrated into numerical mixing model estimate source contributions watershed. Most use co...

In most coastal waters, riverine inputs of suspended particulate matter (SPM) and colored dissolved organic (CDOM) are the primary optically active constituents. Moderate- high-resolution satellite optical sensors, such as Operational Land Imager (OLI) on Landsat-8 MultiSpectral Instrument (MSI) Sentinel-2, offer a synoptic view at high spatial resolution (10–30 m) with weekly revisits allowing...

High-frequency monitoring of suspended particulate matter (SPM) concentration can improve water resource management. Missing high-resolution satellite images could hamper remote-sensing SPM monitoring. This study resolved the problem by applying spatiotemporal fusion technology to obtain high spatial resolution and dense time-series data fill image-data gaps. Three sources (MODIS, Landsat 8, Se...

The Paraiba do Sul (PSR) and Guandu Rivers (GR) water diversion system (120 km long) is located in the main industrial pole of Brazil supplies drinking for 9.4 million people metropolitan region Rio de Janeiro. This study aims to discern trace metals dynamics this complex aquatic system. We used a combined approach geochemical tools such as partitioning, Zn isotopes signatures, multivariate sta...

Continental freshwater contributions are the main long-term control on variability of suspended particulate matter (SPM) concentrations in choked lagoons. The current work aims to assess seasonal interdecadal SPM from Patos Lagoon tributaries, as a case study towards understanding tributaries coastal Thus, an dataset (1984–2020) was collected region (southern Brazil), integrating Landsat series...

OBJECTIVE We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary clearance. METHOD Mucociliary function was quantified by mucociliary transport, ciliary beating frequency and the amount of acid and neutral...

Energetic meteorological events such as frontal passages and hurricanes often impact coastal regions in the northern Gulf of Mexico that influence geochemical processes in the region. Satellite remote sensing data such as winds from QuikSCAT, suspended particulate matter (SPM) concentrations derived from SeaWiFS and the outputs (sea level and surface ocean currents) of a nested navy coastal oce...
