The rock sequence formed by a turbidity current is called a turbidite.

Investigators suggested that a 60-mile-per-hour ( 100 km / h ) submarine landslide or turbidity current of water saturated sediments swept 400 miles ( 600 km ) down the continental slope from the earthquake ’ s epicenter, snapping the cables as it passed.

It contains one of the world's largest turbidity current channel systems, the Northwest Atlantic Mid-Ocean Channel ( NAMOC ), that runs for thousands of kilometers along the sea bottom toward the Atlantic Ocean.

A deep turbidity current channel system, which is about wide and long, runs on the bottom of the sea, near its center from the Hudson Strait into the Atlantic.

Turbidite geological formations have their origins in turbidity current deposits, which are deposits from a form of underwater avalanche that are responsible for distributing vast amounts of clastic sediment into the deep ocean.

Alternatively, the entire sequence may not be present depending on whether the exposed section was at the edge of the turbidity current lobe ( where it may be present as a thin deposit ), or upslope from the deposition centre and manifested as a scour channel filled with fine sands grading up into a pelagic ooze.

Further, situations or conditions that tend to suspend larger particles through water motion ( e. g., increase in a stream current or wave action ) can produce higher values of TSS not necessarily accompanied by a corresponding increase in turbidity.

Supporting the turbidity current origin theory is that deposits of greywacke are found on the edges of the continental shelves, at the bottoms of oceanic trenches, and at the bases of mountain formational areas.

Therefore the conclusion can be drawn that sediment in the canyon head gully failed and flowed down the canyon as a major turbidity current released by this earthquake.

In 1952 American scientists from Columbia University put together the pieces of the sequentially broken cables that led to discovery of the landslide and the first documentation of a turbidity current.

A turbidity current is a current of rapidly moving, sediment-laden water moving down a slope through water, or another fluid.

The current moves because it has a higher density and turbidity than the fluid through which it flows.

The driving force of a turbidity current is obtained from the sediment, which renders the turbid water heavier than the clear water above.

However, the term ' turbidity current ' was adopted to describe a natural phenomenon whose exact nature is often unclear.

The turbulence within a turbidity current isn ’ t always the support mechanism that keeps the sediment in suspension ; however it is probable that turbulence is the primary or sole grain support mechanism in dilute currents (< 3 %).

When the concentration of suspended sediment at the mouth of a river is so large that the density of river water is greater than the density of sea water a particular kind of turbidity current can form called a hyperpycnal plume.

Earthquakes have been linked to turbidity current deposition in many settings, particularly where physiography favors preservation of the deposits and limits the other sources of turbidity current deposition.

Since the famous case of breakage of submarine cables by a turbidity current following the 1929 Grand Banks earthquake, earthquake triggered turbidites have been investigated and verified along the Cascadia subduction Zone, the Northern San Andreas Fault, a number of European, Chilean and North American lakes, Japanese lacustrine and offshore regions and a variety of other settings.

Cloudy amber may be clarified in an oil-bath, as the oil fills the numerous pores to which the turbidity is due.

Water is fresh, with medium turbidity ; the average salinity is 61. 3 mg / L and the calcium bicarbonate content is 7 mg / L.

Though graded bedding can form in many different environments, it is characteristic for turbidity currents.

Eutrophication is apparent as increased turbidity in the northern part of the Caspian Sea, imaged from orbit.

Their productivity is largely dependant upon the turbidity of the water.

Pike are known to prefer water with less turbidity but that is probably related to their dependence on the presence of submersible vegetation and not to their being a sight hunter.

The preserved fauna is primarily benthic and was likely buried by periodic turbidity currents, since most fossils do not show evidence of post mortem transport.

Without vegetation, winds can more easily stir up sediment from the bottom of the lake, which is already a problem due to the lake's shallowness, resulting in greater turbidity and less sunlight reaching the remaining vegetation.

Many WTPs have an initial coagulation / flocculation step that is automatically adjusted to turbidity ( the level of suspended solids, measured in Nephelometric Turbidity Units ) in the incoming water.

As suspended particles ( turbidity ) can provide a growth substrate for microorganisms and can protect them from disinfection treatment, it is extremely important that the water treatment process achieves a good level of removal of suspended particles.

The osphradium is a patch of sensory cells located below the posterior adductor muscle that may serve to taste the water or measure its turbidity, but is probably not homologous with the structure of the same name found in snails and slugs.

Ultraviolet light ( UV ) is very effective at inactivating cysts, in low turbidity water.

Geoduck farming is only conducted in clean, uncontaminated sediments so concern is limited to short-term increases in turbidity and short term effect on benthic organisms.

Average turbidity is 280 g / m < sup > 3 </ sup > at Orenburg and 290 g / m < sup > 3 </ sup > near Kushum 290.

The spartina is generally shorter in the bay than at other sites due to the high tides and the turbidity of the water, reaching around as opposed to elsewhere.

Another method for estimating suspended sediment concentrations is by measuring the turbidity of the water using optical backscatter probes, which can be calibrated against water samples containing a known suspended sediment concentration to establish a regression relationship between the two.

The measurement of turbidity is a key test of water quality.

For many mangrove areas, high turbidity is needed to support certain species, such as to protect juvenile fish from predators.

The most widely used measurement unit for turbidity is the FTU ( Formazin Turbidity Unit ).

A property of the particles — that they will scatter a light beam focused on them — is considered a more meaningful measure of turbidity in water.

This closed anaerobic tank serves as a pre-treatment to allow solids to fall out of suspension and precipitate to the bottom of the reactor to reduce the turbidity of the water.

Ashfalls will be more likely to cause problems for plants that are not designed for high levels of turbidity and which may omit coagulation / flocculation treatment.

Ash will increase water turbidity which can reduce the amount of light reaching lower depths, which can inhibit growth of submerged aquatic plants and consequently affect species which are dependent on them such as fish and shellfish.

In 1998, Bechtel was fined $ 90, 000 for violating water quality laws in New Hampshire for constructing a gas pipeline, which would have leaked sediments into the stream that would increase turbidity and damage wetland habitats.

In water bodies such as lakes, rivers and reservoirs, high turbidity levels can reduce the amount of light reaching lower depths, which can inhibit growth of submerged aquatic plants and consequently affect species which are dependent on them, such as fish and shellfish.

An additional device, which may help measuring turbidity in shallow waters is the Turbidity tube.

The Turbidity tube condenses water in a graded tube which allows determination of turbidity based on a contrast disk in its bottom, being analog to the Secchi disk.

Systems that use filtration other than the conventional or direct filtration must follow state limits, which must include turbidity at no time exceeding 5 NTU.

These criteria are scientific assessments of the effects of turbidity, which are used by states to develop water quality standards for water bodies.

Other natural and anthropogenic substances may cause turbidity ( cloudiness ) which blocks light and disrupts plant growth, and clogs the gills of some fish species.

Mixing the two compounds forms a barium sulfate precipitate, which causes turbidity in the solution.

However, the turbidity, which is caused by wind, prevents photosynthetic stabilisation.

* Short term increases in turbidity, which can affect aquatic species metabolism and interfere with spawning.

Near the continental margins sediment is terrigenous, meaning derived from the land, unlike deep sea sediments which are made of tiny shells of marine organisms, usually calcareous and siliceous, or it can be made of volcanic ash and terrigenous sediments transported by turbidity currents.

These plumes introduce a turbidity which decreases light levels at the bottom and can affect kelp reproduction.

Excess sediment causes high levels of turbidity in water bodies, which can inhibit growth of aquatic plants, clog fish gills and smother animal larvae.
