Introduction: The California Coastal Sediment Management Workgroup (CSMW) has requested proposals from the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to evaluate the transport and fate of fine sediments discharged into California coastal waters. The rationale for this proposed work is a need to better understand the environmental consequences of beach nourishme...

The vertical motion of particles, drops and organisms through density stratified fluids is ubiquitously found in oceans and lakes. Settling dynamics of marine snow particles, rising motion of drops during oil spills, formation of phytoplankton blooms, and diel vertical migration of organisms are just a few of these examples. Transport properties in these examples are modified when the density o...

Advances in the visualization and prediction of turbulence are shedding new light on mass transfer in the turbulent boundary layer. These discoveries have important implications for many topics in environmental science and engineering, from the transport of earth-warming CO2 across the sea-air interface, to nutrient processing and sediment erosion in rivers, lakes, and the ocean, to pollutant r...

Marine tar residues originate from natural and anthropogenic oil releases into the ocean environment and are formed after liquid petroleum is transformed by weathering, sedimentation, and other processes. Tar balls, tar mats, and tar patties are common examples of marine tar residues and can range in size from millimeters in diameter (tar balls) to several meters in length and width (tar mats)....

Concern about marine litter has been rising in the last decades, triggered by the discovery of the great mid-ocean garbage patches. The Mediterranean Sea is strongly affected by the presence of floating litter, as it has a very high amount of waste generated annually per person that eventually ends up in its waters, with plastic objects accounting for a large percentage of all manmade debris. I...

Pore-water solute transport processes acting in addition to molecular diffusion affect sediment biogeochemistry and benthic exchange fluxes. Given the relatively few direct measurements of enhanced transport intensities, there is a need for predictive relationships to calculate enhanced transport parameters from more readily available information. Here, enhanced diffusion coefficients and nonlo...

The transport of neutral amino acids in marine pseudomonad B-16 (ATCC 19855) has been investigated. From patterns of competitive inhibition, mutant analysis, and kinetic data, two active transport systems with overlapping substrate specificities were distinguished and characterized. One system (DAG) served glycine, D-alanine, D-serine, and alpha-aminoisobutyric acid (AIB) and, to a lesser exten...

Abstract This paper presents a novel approach for integrating human and organisational factors into risk analysis. This approach has been developed and applied to a case study in the marine industry, but it can be utilised in other industrial sectors. The approach consists of a BBN model of the maritime transport system that has been developed by taking into account the different actors of the ...

Marine birnavirus (MBVs) infect a wide range of fish and shellfish. Yet their mode of transmission is still unclear. To determine marine plankton serve as a vector for MABVs. The marine birnavirus (MABVs) is a member of Aquabirnavirus and an opportunistic pathogenic form among eukaryotic marine organisms and determine the viral presence in zooplankton as a vector, molecular diagnosis can be use...
