Little Blue Lake
Little Blue Lake is a water-filled doline in the Australian state of South Australia located in the state's south-east in the locality of Mount Schank about south of the municipal seat of Mount Gambier. It is notable locally as a swimming hole and nationally as a cave diving site. It is managed by the District Council of Grant and has been developed as a recreational and tourism venue. Naming The sinkhole's name is attributed to the property of its water to turn blue in colour on an annual basis in a similar manner to the Blue Lake. However in more recent times the sinkhole generally remains green in colour throughout most of the year. This is believed by some to be due to groundwater pollution from agricultural fertilizers increasing the nutrient levels. The lake is also known as Baby Blue and is referenced in caving literature by its Cave Exploration Group of South Australia (CEGSA) Inc. identification number, 5L9.

Mount Schank, South Australia
__NOTOC__ Mount Schank is a locality in the Australian state of South Australia located about south-east of the state capital of Adelaide and south of the municipal seat of Mount Gambier in the south-east of the state. British colonisation of the area began in 1842 when brothers Edward and Fortescue Arthur (sons of Sir George Arthur) established the Mount Schank Station. The Arthur brothers were in continuous conflict with the local Bungandidj people from the time of their arrival. Many of their shepherds absconded, horses were speared and hundreds of their sheep were taken. The brothers had to do much of the shepherding work themselves and often engaged in close combat with "the Blacks". On one occasion Fortescue was slightly wounded after being speared. After capturing and chaining up a Bungandidj man, Edward forced him to reveal the location of their camp. An armed group of settlers was then organised by Edward and the Aboriginal camp was raided and destroyed, with six or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port MacDonnell, South Australia
Port MacDonnell, originally known as ''Ngaranga''Christina Smith, The Booandik Tribe of South Australian Aborigines: A Sketch of Their Habits, Customs, Legends, and Language', Spiller, 1880 is the southernmost town in South Australia. The small port located in the Limestone Coast region about southeast of Adelaide and south of Mount Gambier in the District Council of Grant local government area. The 2016 Australian census which was conducted in August 2016 reports that the locality of Port MacDonnell had a population of 847 of which 671 lived in its town centre. Once a busy shipping port, the town now relies heavily on its fishing and summer tourism industries, particularly rock lobster harvest industry, proclaiming itself "Australia's Southern Rock Lobster Capital". History The area was originally inhabited by the Bungandidj Aboriginal people, who referred to it as ''Ngaranga'', possibly meaning "noisy" or "caves". Their oral history recorded that the dry land previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stromatolites
Stromatolites () or stromatoliths () are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, and Pseudomonadota (formerly proteobacteria). These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral "microbial mats". In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth. Morphology Stromatolites are layered, biochemical, accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), through the action of certain microbial lifeforms, especially cyanobacteria. They exhibit a variety of forms and structures, or morphologies, including conical, stratiform, domal, columnar, and branching ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Phreatic
''Phreatic'' is a term used in hydrology to refer to aquifers, in speleology to refer to cave passages, and in volcanology to refer to a type of volcanic eruption. Hydrology The term phreatic (the word originates from the Greek , meaning "well" or "spring") is used in hydrology and the earth sciences to refer to matters relating to ground water (an aquifer) below the water table. The term 'phreatic surface' indicates the location where the pore water pressure is under atmospheric conditions (i.e. the pressure head is zero). This surface normally coincides with the water table. The slope of the phreatic surface is assumed to indicate the direction of ground water movement in an unconfined aquifer. The phreatic zone, below the phreatic surface where rock and soil is saturated with water, is the counterpart of the vadose zone, or unsaturated zone, above. Unconfined aquifers are also referred to as phreatic aquifers because their upper boundary is provided by the phreatic surface ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Traffic Cone
Traffic cones, also called pylons, witches' hats, road cones, highway cones, safety cones, channelizing devices, construction cones, or just cones, are usually cone-shaped markers that are placed on roads or footpaths to temporarily redirect traffic in a safe manner. They are often used to create separation or merge lanes during road construction projects or automobile accidents, although heavier, more permanent markers or signs are used if the diversion is to stay in place for a long period of time. History Traffic cones were invented by Charles D. Scanlon, an American who, while working as a painter for the Street Painting Department of the City of Los Angeles, was unimpressed with the traditional wooden tripods and barriers used to mark roads which were damaged or undergoing repainting. Scanlon regarded these wooden structures as easily broken, hard to see, and a hazard to passing traffic. Scanlon's rubber cone was designed to return to an upright position when struck by a gl ...

Traffic Sign
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, for example the fingerposts in the United Kingdom and their wooden counterparts in Saxony. With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees. International conventions Various international conventions have helped to achieve a degree of uniformity in Traffic Signing in various countries. Categories Traffic signs can be grouped into several types. For example, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Dispenser
A gasoline pump is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia), petrol pumps (in Commonwealth countries), or gas pumps (in North America). History The first gasoline pump was invented and sold by Sylvanus Bowser in Fort Wayne, Indiana on September 5, 1885, pre-dating the automobile industry- It was commonly used to dispense the kerosene used in lamps and stoves. He later improved upon the pump by adding safety measures, and by adding a hose to directly dispense fuel into automobiles. For a while, the term ''bowser'' was used to refer to a vertical gasoline pump. In the United States this term is now only used for trucks that carry and dispense fuel to large aircraft at airports, but it is still used sometimes in Australia and New Zealand. The first gasoline pump was patented by Norwegian John J. Tokheim in 1901. The Tokh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMC ADO16
The BMC ADO16 is a range of small family cars built by the British Motor Corporation (BMC) and, later, British Leyland. Launched in 1962, it was Britain's best-selling car from 1963 to 1966 and from 1968 to 1971. The ADO16 was marketed under various make and model names; however, the Austin 1100 and Morris 1100 were the most prolific of all the ADO16 variants. The car's ubiquity at the height of its popularity led to it simply being known as the 1100 (eleven-hundred) in its home market. In production for 12 years, the ADO16 range sold 2.1 million units between 1962 and 1974, more than half of those being sold on the UK home market. British Leyland phased out the 1100/1300 between 1971 and 1974 in favour of the Morris Marina and the Austin Allegro. Naming The ADO16 was marketed under the following make and model names: * Austin: 1100, 1300 and 1300GT * Austin: 11/55, America, Apache, De Luxe, Glider and Victoria * Innocenti: Austin I4 and Austin I4S [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
