Pink Lake (Victoria)
Pink Lake (historically known as ''Lake Lochiel'') is a small, circular, salty pink lake on the Western Highway just north of Dimboola in Australia. Granville Stapylton, part of the explorer Thomas Mitchell's 1836 expedition into western Victoria, reconnoitered Pink Lake on 20 July 1836. The lake received its name from its distinctive pink colour. The brightness of the hue varies according to the level of rainfall. Until recently it was assumed that red algae created the pink hue; however, recent research reported by ''Australian Geographic'' describes the colour as result of a pigment produced by the '' Salinibacter ruber bacteria''. A rest-stop overlooks the lake's basin. Salt has been harvested from the lake since the 1860s and on average 20 tonnes a year are harvested by the Mount Zero Olive company working in conjunction with the Barengi Gadjin Land Council. Commercial harvesting stopped in the 1970s but was resumed after negotiations between the Victorian State go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimboola, Victoria
Dimboola is a town in the Shire of Hindmarsh in the Wimmera region of western Victoria, Australia, 334 kilometres north-west of Melbourne. History Situated on the Wimmera River, Dimboola was previously known as 'Nine Creeks'. Following a survey conducted in late 1862 by contractor Frederick Smith of Ararat, a plan for a township in the County of Dimboola was proposed. It was first recognised as being a township when mentioned in the April 1863 edition of the ''Government Gazette''. Before the arrival of white people into the district, the Aborigines called the area Watchegatcheca which had the meaning 'Wattle Tree and White Cockatoos'. The name 'Dimboola' has generally been accepted to have come from the Sinhalese word "dimbula" meaning 'Land of Figs'. The name came from the District Surveyor of the time John George Winchester Wilmot, who had previously lived in Ceylon (now Sri Lanka). The relationship of the name to this area is suggested to have come from 'Upper Regions Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Salt Lake (geography)
A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre). In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lakes, and may also be pink lakes on account of their colour. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake. One saline lake classification differentiates between: *subsaline: 0.5–3‰ (0.05-0.3%) *hyposaline: 3–20‰ (0.3-2%) *mesosaline: 20–50‰ (2-5%) *hypersaline: greater than 50‰ (5%) Properties Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal). The water then evaporates, leaving behind any dissolved salts and thus increasing its salinity, making a salt lake an excellent ...

Pink Lake
A pink lake is a lake that has a red or pink colour. This is often caused by the presence of salt-tolerant algae that produces carotenoids, such as ''Dunaliella salina'', usually in conjunction with specific bacteria, which may vary from lake to lake. Causes Pink lakes arise from a combination of factors, which include climate and hydrology of the continent beneath them, in particular the level of salinity. The orange/pink colour of salt lakes across the world has often been attributed to the green alga ''Dunaliella salina'', but other work has shown that bacteria or archaea are also involved. Alga ''Dunaliella salina'' is the most halophilic (salt-tolerant) alga known and can grow in salinity as high as 35% NaCl (in comparison to seawater, which contains approximately 3% NaCl). The single-celled green alga plays a key role in primary production in hypersaline environments around the world. At high salinity, temperature and light, this alga accumulates the red carotenoid ...

Western Highway (Victoria)
The Western Highway is the Victorian part of the principal route linking the Australian cities of Melbourne and Adelaide, with a length of approximately of single carriageway, then of dual carriageway known as the Western Freeway. It is a part of the National Highway network and designated routes A8 and M8. The western end continues into South Australia as the Dukes Highway, the next section of the Melbourne–Adelaide National Highway. The Western Freeway joins Melbourne's freeway network via the Western Ring Road, in the western suburbs of Melbourne. The Western Highway is the second busiest national highway in Australia, in terms of freight movements, with over five million tonnes annually. It provides the link between the eastern seaboard and South Australia and Western Australia. The towns along the way, including Ballarat, Ararat, Stawell and Horsham, are agricultural and manufacturing centres. Plans are underway for the freeway to be extended west to Ararat, an ...

Thomas Mitchell (explorer)
Sir Thomas Livingstone Mitchell (15 June 1792 – 5 October 1855), surveyor and explorer of Southeastern Australia, was born at Grangemouth in Stirlingshire, Scotland. In 1827 he took up an appointment as Assistant Surveyor General of New South Wales. The following year he became Surveyor General and remained in this position until his death. Mitchell was knighted in 1839 for his contribution to the surveying of Australia. Early life Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire. Peninsular War On the death of his uncle, he joined the British army in Portugal as a volunteer in the Peninsular War, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets).

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around their re ...

Salinibacter Ruber
''Salinibacter ruber'' is an extremely halophilic red bacterium, first found in Spain in 2002. Habitat ''Salinibacter ruber'' was found in saltern crystallizer ponds in Alicante and Mallorca, Spain in 2002 by Antón et al. This environment has very high salt concentrations, and ''Salinibacter ruber'' itself cannot grow at below 15% salt concentration, with an ideal concentration between 20 and 30%. It has also been found in pink lakes in Australia. This bacterium is notable for its halophilic lifestyle, a trait exhibited primarily by members of Archaea. In general, bacteria do not play a large role in microbial communities of hypersaline brines at or approaching NaCl saturation. However, with the discovery of ''S. ruber'', this belief was challenged. It was found that ''S. ruber'' made up from 5% to 25% of the total prokaryotic community of the Spanish saltern ponds. ca: ''Salinibacter ruber'' was found in saltern crystallizer ponds in Alicante and Mallorca, Spain in 20 ...

Barengi Gadjin Land Council Aboriginal Corporation
The Barengi Gadjin Land Council was formed in 2005 to represent the Wotjobaluk, Jardwadjali (also known as Jaadwa), Wergaia and Jupagalk peoples. The Council manages native title rights across Western Victoria in an area "roughly described as the Wimmera River from the head of the Yarriambiack Creek through to Outlet Creek at the northern end of Lake Albacutya". The Council is governed by a board of directors representing various family groups and has offices in Wail and Horsham. The current chairperson is Dylan Clark. The Land Council recently condemned graffiti at Aboriginal sites in the Grampians National Park and lodged a native title claim for permission to hunt inside the Park in 2016.

Lake Hillier
Lake Hillier is a salt lake, saline lake on the edge of Middle Island (Western Australia), Middle Island, the largest of the islands and islets that make up the Recherche Archipelago in the Goldfields-Esperance region, off the south coast of Western Australia. It is particularly notable for its pink colour. A long and thin shore divides the Southern Ocean (by some definitions, the Indian Ocean) from the lake. Description Lake Hillier is about in length by about in width. The lake is surrounded by a rim of sand and a dense woodland of paperbark and eucalyptus trees with a narrow strip of sand dunes covered by vegetation separating its northern edge from the northern coast of Middle Island. The most notable feature of the lake is its pink, vibrant colour. The vibrant colour is permanent, and does not alter when the water is taken in a container. The pink colour is believed to be due to the presence of the organism, ''Dunaliella salina''. The Extreme Microbiome Project, part ...
