FACTORS INFLUENCING ESTUARY SEDIMENT DISTRIBUTION

Microplastic Distribution at Different Sediment Depths in an Urban Estuary

As plastic production increases, so to do the threats from plastic pollution. Microplastics (defined as plastics <5mm) are a subset of marine debris about which we know less than we do of larger debris items, though they are potentially ubiquitous in the marine environment. To quantify the distribution and change in microplastic densities through time, we sampled sediment cores from an estuary ...

Distribution of organochlorine pesticides in a sediment profile of the Pearl River estuary.

Geostatistical Modeling of Intertidal Sediment Distribution in the Ba Lat Estuary, Vietnam

Intertidal sediment grain size is one of the environmental parameters that can explain the interaction between the marine and terrestrial environments. Geostatistics has been widely used to model spatial distribution of many geological objects. However, there have been a few researches concerning application to grain size distribution. The aim of this study is to clarify surface sediment distri...

An analytical model of the equilibrium distribution of suspended sediment in an estuary

An analytical solution of the equilibrium distribution of suspended sediment concentrations (SSC) in an estuary along the longitudinal axis is extended to include variable width. A turbidity maximum is formed at the convergence of fluxes from freshwater discharge and (vertically well mixed) salinity gradients. Simple scaling relationships control the longitudinal distribution of SSC and depend ...

Regional patterns and local variations of sediment distribution in the Hudson River Estuary

The Hudson River Benthic Mapping Project, funded by the New York State Department of Environmental Conservation, resulted in a comprehensive data set consisting of high-resolution multibeam bathymetry, sidescan sonar, and sub-bottom data, as well as over 400 sediment cores and 600 grab samples. This detailed data set made it possible to study the regional pattern and the local variations of the...
