Dawesville Channel
Dawesville Channel (also known as Dawesville Cut) is an artificial channel between the Peel-Harvey Estuary and the Indian Ocean at Dawesville, about south of Perth in Western Australia. It is south of the regional city of Mandurah and north of Yalgorup National Park. The channel alleviated a serious environmental problem, by allowing seawater from the Indian Ocean to move in and out of the estuarine system using the daily tidal movements, preventing the build-up of algae. Before the construction of the canal, much of the estuarine system, which is approximately and about deep, had become eutrophic. The ability of the system to support the natural flora and fauna had become seriously degraded, and the smell of rotting algae, particularly during the summer months, had caused increasing complaints from residents. Stocks of normally-abundant fish and crabs had become depleted and recreational use of the estuaries was adversely affected. The deteriorating conditions became a ...

Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wannanup, Western Australia
Wannanup (also known as Port Bouvard, Avalon and Florida) is a residential suburb in Western Australia, located southwest of Mandurah and south-southwest of the state capital, Perth. It is surrounded on three sides by water – the Indian Ocean to the west, the Harvey Estuary to the east and the Dawesville Channel to the south – and is home to the Port Bouvard development. It is one of four suburbs which lie on an island created by the building of the Dawesville Channel. History Wannanup is the original Aboriginal name for the suburb known as Florida. However, upon the development of the Dawesville Channel, the suburb was split in half. The southern section was placed in Dawesville while the northern section was regazetted as Wannanup in 1996. The 21st century has seen the landscape of Wannanup transformed, with the development of Port Bouvard transforming the community from that of a sleepy fishing settlement to a commuter suburb and holiday destination. The Northport esta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forrest Highway
Forrest Highway is a highway in Western Australia's Peel and South West regions, extending Perth's Kwinana Freeway from east of Mandurah down to Bunbury. Old Coast Road was the original Mandurah–Bunbury route, dating back to the 1840s. Part of that road, and the Australind Bypass around Australind and Eaton, were subsumed by Forrest Highway. The highway begins at Kwinana Freeway's southern terminus in Ravenswood, continues around the Peel Inlet to Lake Clifton, and heads south to finish at Bunbury's Eelup Roundabout. There are a number of at-grade intersections with minor roads in the shires of Murray, Waroona, and Harvey including Greenlands Road and Old Bunbury Road, both of which connect to South Western Highway near Pinjarra. The settlement of Australind by the Western Australian Land Company in 1840–41 prompted the first real need for a good quality road to Perth. A coastal Australind–Mandurah route was completed by 2 November 1842. Though the road was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Work For The Dole
Work for the Dole is an Australian Government program that is a form of workfare, or work-based welfare. It was first permanently enacted in 1998, having been trialled in 1997. It is one means by which job seekers can satisfy the "mutual obligation requirements" to receive the Newstart Allowance, now replaced by the JobSeeker Payment. Other "mutual obligation" measures can include: accredited study, part-time work, Australian Army Reserves, and volunteer work. Under the Howard Government, the scheme was compulsory and targeted the long-term unemployed. Shortly after the Rudd Government was formed it became voluntary. From 1 July 2015, Work for the Dole became effectively compulsory for the majority of Newstart Allowance recipients. On 20 March 2020, during the COVID-19 pandemic, Work for the Dole was suspended, alongside all other mutual obligation requirements. Basic Work for the Dole Placements are available in a wide range of areas including heritage, the environment, arts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcoa
Alcoa Corporation (an acronym for Aluminum Company of America) is a Pittsburgh-based industrial corporation. It is the world's eighth-largest producer of aluminum. Alcoa conducts operations in 10 countries. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling. In May 2007, Alcoa Inc. made a US$27 billion hostile takeover bid for Alcan in an attempt to form the world's largest aluminum producer. The bid was withdrawn when Alcan announced a friendly takeover by Rio Tinto in July 2007. On November 1, 2016, Alcoa Inc. split into two entities: a new one called Alcoa Corporation, which is engaged in the mining and manufacture of raw aluminum, and the renaming of Alcoa Inc. to Arconic Inc., which processes aluminum and other metals. After relocating its corporate operations to New York City ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bauxite Tailings
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and ...

Algal Blooms
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other organ ...

Nodularia Spumigena
''Nodularia'' is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae. They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans, the Peel-Harvey Estuary in Western Australia or the Baltic Sea. ''Nodularia'' cells occasionally form heavy algal blooms. Some strains produce a cyanotoxin called nodularin R, which is harmful to humans. The type species for the genus is '' Nodularia spumigena'' Mertens ex Bornet & Flahault, 1886. Morphology ''Nodularia'' may form solitary filaments or groups of filaments. They reproduce by the formation of hormogonia Hormogonia are motile filaments of cells formed by some cyanobacteria in the order Nostocales and Stigonematales. They are formed during vegetative reproduction in unicellular, filamentous cyanobacteria, and some may contain heterocysts and ..., filament breakage, and by akinetes .Martin Dworkin and Stanley Falkow, 2006 See also Kruger, T., Oelmuller, R., and Luckas, B. ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
