Exempel på hur man kan använda ANOXIC i en mening

• They inhabit sand and mud beneath shallow coastal waters and can survive in relatively anoxic environments.
• These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying the decomposition of both gross and fine biological features until long after a durable impression was created in the surrounding matrix.
• Methanogens are common in various anoxic environments, such as marine and freshwater sediments, wetlands, the digestive tracts of animals, wastewater treatment plants, rice paddy soil, and landfills.
• Purple sulfur bacteria are generally found in illuminated anoxic zones of lakes and other aquatic habitats where hydrogen sulfide accumulates and also in "sulfur springs" where geochemically or biologically produced hydrogen sulfide can trigger the formation of blooms of purple sulfur bacteria.
• In dimictic, eutrophic lakes, the hypolimnion is often anoxic throughout a majority of the stratified period.
• It is not clear whether the magnetite precipitates upon the first contact with oxygen, then oxidizes to ferric compounds, or whether the ferric compounds are reduced when exposed to anoxic conditions upon burial beneath the sediment surface and reoxidized upon exhumation at the surface.
• Greensand forms in anoxic marine environments that are rich in organic detritus and low in sedimentary input.
• Purple bacteria are anoxygenic phototrophs widely spread in nature, but especially in aquatic environments, where there are anoxic conditions that favor the synthesis of their pigments.
• Meromictic lakes are fairly rare; they have been extensively studied, in part because their sediments can preserve a historical record extending back thousands of years, and because of the euxinic (anoxic, sulfidic) conditions which can form in the deep water.
• Notably, Milankovitch cycles have been theorised to be important modulators of biogeochemical cycles during oceanic anoxic events, including the Toarcian Oceanic Anoxic Event, the Mid-Cenomanian Event, and the Cenomanian-Turonian Oceanic Anoxic Event.
• Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, allowing waters to go anoxic, and desiccation used to dry fouling out so that it may slough off or become easier to remove through manual processes.
• The concept of the oceanic anoxic event (OAE) was first proposed in 1976 by Seymour Schlanger (1927–1990) and geologist Hugh Jenkyns and arose from discoveries made by the Deep Sea Drilling Project (DSDP) in the Pacific Ocean.
• pyrophilus thrives where the oxic and anoxic zones meet in these environments because of the high availability of hydrogen and thiosulfate.
• However, this may be an issue if the electrode has to remain immersed on-line for prolonged period of time, or is inaccessible for particular constrains related to the nature of the measurements itself (geochemical measurements under elevated water pressure in harsh environments or under anoxic or reducing conditions easily disturbed by atmospheric oxygen ingress or pressure changes).
• Arsenates occur in oxygenated waters, which have a high pe, while arsenites are the main arsenic species in anoxic waters with a low pe.
• A decrease in the anoxic conditions of the Cambrian, and an increase in euxinic conditions (or an increase in hydrogen sulfide concentrations) of the Early Ordovician are also believed to be an initiator of the Great Ordovician Biodiversification Event.
• In this era of flow regulation and flood curtailment by dams, which control the flood events that remove fine sediment, and chronic siltation from poor agricultural practices, the eggs may now frequently land in anoxic fine sediment and organic matter — including in weir pools — and fail to survive.
• pseudacorus grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH, and anoxic soils.
• Being generally microaerophilic they are adapted to live in transition zones where the oxic and anoxic waters mix.
• While often described as the "only fjord on the East Coast", it lacks the extreme vertical relief and anoxic sediments associated with Norwegian fjords, and is now called a fjard by officials — a smaller drowned glacial embayment.
