Vertical Distribution of Microplastics in the Water Column and Surficial Sediment from the Milwaukee River Basin to Lake Michigan.

Environmental Science and Technology, 2019
Microplastic contamination was studied along a freshwater continuum from inland streams to the Milwaukee River estuary to Lake Michigan and vertically from the water surface, water subsurface, and sediment.

Investigating uncertainty and parameter sensitivity in bedform analysis by using a Monte Carlo approach [PDF]

Earth Surface Dynamics
Precise and reliable information about bedforms regarding geometry and dynamics is relevant for many applications – such as ensuring safe conditions for navigation along the waterways, parameterizing the roughness of the riverbed in numerical models, or ...

Rethinking Environmental Flows for the Yellow River Estuary by Trading Off Crop Yield and Ecological Benefits

Agriculture, 2021
To solve the water use conflicts between agriculture and ecosystems in arid and semiarid areas, a multi-objective trade-off analysis method was applied to determine the environmental flows (e-flows) for the Yellow River Estuary, by considering the ...

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

GlobSed: Updated Total Sediment Thickness in the World's Oceans

Geochemistry Geophysics Geosystems, 2019
We present GlobSed, a new global 5‐arc‐minute total sediment thickness grid for the world's oceans and marginal seas. GlobSed covers a larger area than previously published global grids and incorporates updates for the NE Atlantic, Arctic, Southern Ocean,

Formation of siliceous sediments in brandy after diatomite filtration [PDF]

, 2015
Brandy is quite a stable spirit but sometimes light sediment appears. This sediment was separated and analysed by IR and SEM-EDX. It was revealed that the sediment is composed mostly of silica and residual organic matter.

Sampling Strategies to Improve Passive Optical Remote Sensing of River Bathymetry

Remote Sensing, 2018
Passive optical remote sensing of river bathymetry involves establishing a relation between depth and reflectance that can be applied throughout an image to produce a depth map. Building upon the Optimal Band Ratio Analysis (OBRA) framework, we introduce

Variable sediment oxygen uptake in response to dynamic forcing [PDF]

, 2010
Seiche-induced turbulence and the vertical distribution of dissolved oxygen above and within the sediment were analyzed to evaluate the sediment oxygen uptake rate (JO2), diffusive boundary layer thickness (δDBL), and sediment oxic zone depth (zmax) in ...

Reduced sediment transport in the Yellow River due to anthropogenic changes

, 2016
The erosion, transport and redeposition of sediments shape the Earth's surface, and affect the structure and function of ecosystems and society(1,2). The Yellow River was once the world's largest carrier of fluvial sediment, but its sediment load has ...

Deficiency and excess of groundwater iodine and their health associations

Nature Communications, 2022
Both iodine deficiency and excess could cause thyroid disorders. By creating a national map of groundwater iodine throughout China, the authors reveal the spatial responses of diverse health risks to iodine in continental groundwater.
