In the estuary and nearshore environments, suspended particulate matter (SPM) plays a particularly important role. This article presents study on microbial communities in euphotic zone of China’s estuarine regions. The used various analytical techniques, including ICP-OES, SR-XRD, confocal Raman microscopy, ESEM, EDX, to investigate spatial distribution elemental mineral compositions matters. f...

Color of seawater has become an integral tool in understanding surface marine ecosystems and processes. In this paper we seek to assess the correlations and consequently the potential of using shipborne remote sensing products to infer marine environmental parameters. Typical seawater parameters are chlorophyll–a (chl–a), colored dissolved organic material (CDOM), suspended particulate material...

A process-based sediment transport model is presented that combines the knowledge of sediment transport in rivers and estuaries with the understanding of physical processes specific for the shelf seas. Due to formation of bottom Ekman spiral, the near-bottom current and hence the sediment transport deviate from the direction of surface current. The model takes into account velocity veering indu...

Triclosan (TCS) and triclocarban (TCC) are two active ingredients widely used in many home and personal care products. Multimedia fate of TCS and TCC in the Dongjiang River basin, South China were addressed by the developed level III fugacity model based on their usage. Under the assumption of steady state, the concentrations in air, water, soil, sediment, suspended particulate matter (SPM) and...

The implementation of accurate atmospheric correction is a prerequisite for satellite observation and water quality monitoring in coastal areas. The potential of the fast-line-of-sight atmospheric analysis of spectral hypercubes (FLAASH) was investigated here for the medium resolution imaging spectrometer (MERIS). As the comparison between discrete field sampling points and macro-scale satellit...

A large number of sediment samples representing most of the active mud accumulation areas of the Gulf of Finland were studied for total cadmium, chromium, lead, mercury, arsenic, copper and zinc. The highest concentrations of metals were found in sediment surfaces in the easternmost part of the Gulf, which is influenced by the inflow of the Neva river and the loads of the city of St. Petersburg...

The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study. The experimental design was completely randomized and was performed in 9 rectangular tanks (1.6 m3) with three treatments (constructed wetlands) and three replicates. The treatment typ...

The paper presents the results of a comparison water turbidity and suspended particulate matter concentration (SPM) obtained from quasi-synchronous in situ satellite remote-sensing data. Field measurements small boat were performed April May 2019, northeastern part Black Sea, mouth area Mzymta River. measuring instruments methods included sensor mounted on CTD (Conductivity, Temperature, Depth)...

Missing data is a common issue in remote sensing. Data reconstruction through multiple satellite sources has become one of the most powerful ways to solve this issue. Continuous monitoring suspended particulate matter (SPM) arid lakes vital for water quality solutions. Therefore, research aimed develop and evaluate performance two image strategies, spatio-temporal fusion reflectance inversion S...

This study aims to examine the physicochemical parameters of seawater (temperature, pH, salinity, dissolved oxygen, suspended particulate matter, ammoniumnitrogen, nitrite-nitrogen, nitrate-nitrogen, and phosphatephosphorus, burnable organic matter in sediment), possible effects pollution Sığacık Bay where different anthropogenic activities are carried out. Samples surface (0 m), bottom (2 sedi...
