Ravine Des Casoars
Ravine des Casoars ( English: Ravine of the Cassowaries) is a gorge and an associated drainage basin in the Australian state of South Australia located on the west coast of Kangaroo Island about west of Kingscote. Description The Ravine des Casoars is a steep sided valley of length with an east–west alignment and with a maximum depth of . The ravine drains a catchment area of approximately within the western end of Kangaroo Island. The ravine meets the sea on the west coast of Kangaroo Island via a gap of about width in the coastline’s continuous cliff line. A beach is located between the two headlands. The beach and an accompanying sand dune extends about back into the south side of the ravine to an elevation of about while a creek and an associated lagoon flows on the north side of the ravine. The base of the cliffs on the northern side of the beach had eroded with the result of caves being formed. As of 1965, two caves were described. The first known as ‘ ...

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers.

South Australian Museum
The South Australian Museum is a natural history museum and research institution in Adelaide, South Australia, founded in 1856 and owned by the Government of South Australia. It occupies a complex of buildings on North Terrace in the cultural precinct of the Adelaide Parklands. Plans are under way to move much of its Australian Aboriginal cultural collection (the largest in the world), into a new National Gallery for Aboriginal Art and Cultures. History 19th century There had been earlier attempts at setting up mechanics' institutes in the colony, but they struggled to find buildings which could hold their library collections and provide spaces for lectures and entertainments. In 1856, the colonial government promised support for all institutes, in the form of provision the first government-funded purpose-built cultural institution building. The South Australian Institute, incorporating a public library and a museum, was established in 1861 in the rented premises of the ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

Cassowary
Cassowaries (; Biak: ''man suar'' ; ; Papuan: ''kasu weri'' ) are flightless birds of the genus ''Casuarius'', in the order Casuariiformes. They are classified as ratites, flightless birds without a keel on their sternum bones. Cassowaries are native to the tropical forests of New Guinea (Western New Guinea and Papua New Guinea), the Moluccas (Seram and Aru Islands), and northeastern Australia.. Three cassowary species are extant. The most common, the southern cassowary, is the third-tallest and second-heaviest living bird, smaller only than the ostrich and emu. The other two species are the northern cassowary and the dwarf cassowary; the northern cassowary is the most recently discovered and the most threatened. A fourth, extinct, species is the pygmy cassowary. Cassowaries are very wary of humans, but if provoked, they are capable of inflicting serious, even fatal, injuries. They are known to attack both dogs and people. The cassowary has often been labelled "the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kangaroo Island Emu
The Kangaroo Island emu or dwarf emu (''Dromaius novaehollandiae baudinianus'') is an extinct subspecies of emu. It was restricted to Kangaroo Island, South Australia, which was known as ''Ile Decrés'' by the members of the Baudin expedition. It differed from the mainland emu mainly in its smaller size. The subspecies became extinct by about 1827. Taxonomy It was first recorded in 1802 by Matthew Flinders and reported to be quite common around Nepean Bay. The first bones of the subspecies were discovered in 1903 at The Brecknells, sandhills on the west side of Cape Gantheaume. Initially, there was confusion regarding the taxonomic status and geographic origin of the Kangaroo Island emu, particularly with respect to their relationship to the King Island emu, which were also transported to France as part of the same expedition. The expeditions logbooks failed to clearly state where and when dwarf emu individuals were collected. This led to both taxa being interpreted as a singl ...

Nicolas Baudin
Nicolas Thomas Baudin (; 17 February 175416 September 1803) was a French explorer, cartographer, naturalist and hydrographer, most notable for his explorations in Australia and the southern Pacific. He carried a few corms of Gros Michel banana from Southeast Asia, depositing them at a botanical garden on the Caribbean island of Martinique. Biography Early career Born a commoner in Saint-Martin-de-Ré on the Île de Ré on 17 February 1754, Nicolas Baudin joined the merchant navy as an apprentice () at the age of 15; he was then "of average height with brown hair". He then joined the French East India Company at the age of 20 on ''Flamand''. He returned from India on ''L'Étoile'' and arrived at Lorient. At the beginning of 1778, he was to set sail from Nantes on ''Lion'' as second lieutenant. It was a ship equipped by his uncle, Jean Peltier Dudoyer, at the request of the Americans, which would become a privateer and be renamed ''Deane''. At first the Minister for the N ...

Baudin Expedition To Australia
The Baudin expedition of 1800 to 1803 was a French expedition to map the coast of New Holland (now Australia). Nicolas Baudin was selected as leader in October 1800. The expedition started with two ships, '' Géographe'', captained by Baudin, and '' Naturaliste'' captained by Jacques Hamelin, and was accompanied by nine zoologists and botanists, including Jean-Baptiste Leschenault de la Tour, François Péron and Charles-Alexandre Lesueur as well as the geographer Pierre Faure. History Expedition Napoléon Bonaparte, as First Consul, formally approved the expedition "to the coasts of New Holland", after receiving a delegation consisting of Baudin and eminent members of the Institut National des Sciences et Arts on 25 March 1800. The explicit purpose of the voyage was to be "observation and research relating to Geography and Natural History." The Baudin expedition departed Le Havre, France, on 19 October 1800.

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Du Couedic
Cape du Couedic is a headland in the Australian state of South Australia located on the southwest tip of Kangaroo Island in the locality of Flinders Chase. It was named after a French naval officer, , by the Baudin expedition to Australia during January 1803. It is the site for the Cape du Couedic Lighthouse. It is currently located within the Flinders Chase National Park. Description Cape du Couedic is located southwest of the municipal seat of Kingscote at the most southwesterly point of the Kangaroo Island coast. It is the termination for a pair of coastlines - the western coastline extending from Cape Borda in the north and the southern coastline extending from Cape Willoughby in the east. It is described as "a narrow promontory about 1 mile long" (i.e. ) and that "its SW face slopes to the sea whereas its N and S sides are steep." Formation, geology & oceanography Cape du Couedic was formed when the sea reached its present level 7,500 years ago after sea levels started ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aboriginal Australians
Aboriginal Australians are the various indigenous peoples of the Mainland Australia, Australian mainland and many of its islands, excluding the ethnically distinct people of the Torres Strait Islands. Humans first migrated to Australia (continent), Australia 50,000 to 65,000 years ago, and over time formed as many as 500 List of Aboriginal Australian group names, language-based groups. In the past, Aboriginal people lived over large sections of the continental shelf. They were isolated on many of the smaller offshore islands and Tasmania when the land was inundated at the start of the Holocene Interglacial, inter-glacial period, about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people, Makassar people of modern-day Indonesia. Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
