Leanne Armand
Leanne Armand (20 February 1968 – 4 January 2022) was an Australian professor of marine science. She was an expert in the identification of diatoms in the Southern Ocean. She was known for her contributions to the understanding of past Southern Ocean dynamics and sea ice as a result of her knowledge of diatom distributions and ecology. Her research focused on the distribution of diatoms, a single-cell microscopic phytoplankton, within the Southern Ocean. Different species of diatoms inhabit different regions of the ocean, depending on the physical characteristics (e.g. temperature, salinity and nutrients) of the water mass. Understanding diatom distributions and how their skeletons are preserved in the fossil record contained within sediment cores taken from the ocean floor can provide information about past climate regimes, including ocean temperatures and sea ice extent. Armand also studied diatoms in the Southern Ocean near Kerguelen and Heard Islands to examine their rol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George V Coast
George V Coast () is that portion of the coast of Antarctica lying between Point Alden, at 148°2′E, and Cape Hudson, at 153°45′E. Portions of this coast were sighted by the US Exploring Expedition in 1840. It was explored by members of the Main Base party of the Australasian Antarctic Expedition (1911–14) under Douglas Mawson who named this feature for King George V of the United Kingdom. The segment of land between these lines of longitude is referred to as George V Land. Mertz Glacier is located in this area.

Kerguelen Islands
The Kerguelen Islands ( or ; in French commonly ' but officially ', ), also known as the Desolation Islands (' in French), are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than from Madagascar. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district. The main island, Grande Terre, is in area, about three quarters of the size of Corsica, and is surrounded by a further 300 smaller islands and islets, forming an archipelago of . The climate is harsh and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indig ...

Hobart
Hobart ( ; Nuennonne/Palawa kani: ''nipaluna'') is the capital and most populous city of the Australian island state of Tasmania. Home to almost half of all Tasmanians, it is the least-populated Australian state capital city, and second-smallest if territories are taken into account, before Darwin, Northern Territory. Hobart is located in Tasmania's south-east on the estuary of the River Derwent, making it the most southern of Australia's capital cities. Its skyline is dominated by the kunanyi/Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the five local government areas that cover the city. It has a mild maritime climate. The city lies on country which was known by the local Mouheneener people as nipaluna, a name which includes surrounding features such as ...

Diatoms
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...

Micropaleontology
Micropaleontology (American spelling; spelled micropalaeontology in European usage) is the branch of paleontology (palaeontology) that studies microfossils, or fossils that require the use of a microscope to see the organism, its morphology and its characteristic details. Microfossils Microfossils are fossils that are generally between 0.001mm and 1 mm in size, the study of which requires the use of light or electron microscopy. Fossils which can be studied by the naked eye or low-powered magnification, such as a hand lens, are referred to as macrofossils. For example, some colonial organisms, such as Bryozoa (especially the Cheilostomata) have relatively large colonies, but are classified by fine skeletal details of the small individuals of the colony. In another example, many fossil genera of Foraminifera, which are protists are known from shells (called "tests") that were as big as coins, such as the genus '' Nummulites''. Microfossils are a common feature of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monaro (New South Wales)
Monaro ( ), once frequently spelled "Manaro", or in early years of settlement "Maneroo" is a region in the south of New South Wales, Australia. A small area of Victoria near Snowy River National Park is geographically part of the Monaro. While the Australian Capital Territory is not considered part of the region, some towns in the Monaro have close links with Canberra. The Snowy Monaro Regional Council was established in 2016 which comprises the former Bombala, Cooma-Monaro and Snowy River Local Government Areas. The area was traditionally inhabited by Ngarigo, Walgalu, Bidawal and Southern Ngunnawal people. It boasts of snowfields, expansive timber forests and the Snowy River. Holden's 'Monaro' Coupe (and later sedan) models ( 1967-1977, 2001-2006, 1973-1974 (Sedan)) were named after the area. Geography The Monaro region is a plateau area lying about 1000 metres above sea level, extending from the valley of the Murrumbidgee River in the north to the Errinundra Plateau in t ...

Alice Springs
Alice Springs ( aer, Mparntwe) is the third-largest town in the Northern Territory of Australia. Known as Stuart until 31 August 1933, the name Alice Springs was given by surveyor William Whitfield Mills after Alice, Lady Todd (''née'' Alice Gillam Bell), wife of the telegraph pioneer Sir Charles Todd. Known colloquially as 'The Alice' or simply 'Alice', the town is situated roughly in Australia's geographic centre. It is nearly equidistant from Adelaide and Darwin. The area is also known locally as Mparntwe to its original inhabitants, the Arrernte, who have lived in the Central Australian desert in and around what is now Alice Springs for tens of thousands of years. Alice Springs had an urban population of 26,534 Estimated resident population, 30 June 2018. in June 2018, having declined an average of 1.16% per year the preceding five years. The town's population accounts for approximately 10 per cent of the population of the Northern Territory. The town straddles th ...

Rotary Youth Exchange
Rotary Youth Exchange (RYE) is a Rotary International student exchange program for students in secondary school. Since 1929, Rotary International has sent young people around the globe to experience new cultures. Currently, about 9,000 students are sponsored by Rotary Clubs every year. Typically, students are sent to another country for a year-long stay, generally living with multiple host families during the year and being expected to perform daily tasks within the household as well as attend school in the host country. Short term exchange programs are also quite common. These typically involve direct student exchanges between two families arranged through Rotary to coincide with major school holiday periods. History The Rotary Club of Copenhagen, Denmark initiated the first Rotary exchange in 1927, and the Rotary Club of Nice, France followed suit soon after in 1929. Although exchanges today usually last ten months, the first exchanges took place during school vacations for o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
