During the past 50 years, the turbidite paradigm has promoted many myths related to deep-water turbidite deposition. John E. Sanders (1926–1999), a pioneering process sedimentologist, first uncovered many of these turbidite myths. This paper provides a reality check by undoing 10 of these turbidite myths. Myth No. 1: turbidity currents are non-turbulent flows with multiple sediment-support mech...

BACKGROUND Studies suggest that routine variations in public drinking water turbidity may be associated with endemic gastrointestinal illness. We systematically reviewed the literature on this topic. METHODS We searched databases and websites for relevant studies in industrialized countries. Studies investigating the association between temporal variations in drinking water turbidity and inci...

Penaeus japonicus juveniles were exposed for 3 wk to different turbidities of suspended sediments: control [2 + 2 nephelometric turbidity units (NTU)], medium turbidity (35 f 15 NTU) and high turbidity (65 f 15 NTU). The mortality rate increased after exposure to high turbidity Exposed late luveniles became less tolerant to changes in ambient salinity and showed hlgher mortalities at low salini...

Coagulation-flocculation followed by sedimentation and filtration is the most commonly used water treatment process , in which turbidity or particles removal is strongly dependent on proper coagulant dosage, effect of pH ,effect of time, jar test and settling column tests were perform. In the method the seeds were treated with different solvents of NaCl and NaOH to extract the active coagulant ...

—Turbidity in aquatic systems can change rapidly, affecting the visual ability of predators. Increased turbidity is known to reduce the reactive distance and foraging success of some planktivores and insectivores, leading to decreased growth rates. However, little is known about the effects of turbidity on prey selection by piscivores. We examined the interactions between largemouth bass Microp...

Turbidity sensors can be used to continuously monitor the evolution of pollutant mass discharge. For two sites within the Paris combined sewer system, continuous turbidity, conductivity and flow data were recorded at one-minute time intervals over a one-year period. This paper is intended to highlight the variability in turbidity dynamics during wet weather. For each storm event, turbidity resp...

Seasonal turbidity patterns and event-level hysteresis analysis of turbidity verses discharge in four 1 km headwater catchments in California’s Sierra Nevada indicate localized in-channel sediment sources and seasonal accumulation-depletion patterns of stream sediments. Turbidity signals were analyzed for three years in order to look at the relationships between seasonal turbidity trends, event...

Coastal water-quality is both a primary driver and also a consequence of coastal ecosystem health. Turbidity, a measure of dissolved and particulate water-quality matter, is a proxy for water quality, and varies on daily to interannual periods. Turbidity is influenced by a variety of factors, including algal particles, colored dissolved organic matter, and suspended sediments. Identifying which...

Increasing turbidity in coastal waters in the North Atlantic and adjacent seas has raised concerns about impacts on Atlantic cod (Gadus morhua) using these areas as nurseries. A previous experiment (Meager et al. 2005 Can. J. Fish. Aquat. Sci. 62, 1978-1984) has shown that turbidity (up to 28 beam attenuation m-1) had little effect on the foraging rate of juvenile cod. Although this was attribu...

OBJECTIVE Abdominal aortic aneurysm (AAA) is characterized by widening of the aorta. Once the aneurysm exceeds 5.5 cm, there is a 10% risk of death due to rupture. AAA is also associated with mortality due to other cardiovascular disease. Our aim was to investigate clot structure in AAA and its relationship to aneurysm size. METHODS AND RESULTS Plasma was obtained from 49 controls, 40 patient...
