Boat Harbour (Kurnell)
Boat Harbour is a small beach located on the southern side of the Botany Bay National Park in Kurnell, Sydney, New South Wales, Australia. History The original inhabitants of the land were the Gweagal Aborigines who were a clan of the Tharawal (or Dharawal) tribe of Indigenous Australians. They are the traditional custodians of the southern geographic areas of Sydney. The first land grant was issued in 1815. of land on the Kurnell Peninsula which also included Boat Harbour was issued to James Birnie, a whaler and merchant. He named his land ‘Alpha Farm’ and built himself a cottage. When James Birnie was declared insane in 1828, John Connell gained possession of his property. John Connell died in 1848 leaving his estate to his grandsons. In 1861 the property was sold to Thomas Holt who purchased the land for £3275. Holt, originally from Yorkshire, sailed into Sydney sometime in 1842. He made his fortune during the gold rushes of the early 1850s. Holt moved to Sutherland, a ...

Kurnell
Kurnell is a suburb in Sydney, in the state of New South Wales, Australia. It is south of the Sydney central business district, in the local government area of the Sutherland Shire along the east coast. Cronulla and Woolooware are the only adjacent suburbs. La Perouse is located opposite, on the northern headland of Botany Bay. The Cronulla sand dunes are on the south eastern headland of Botany Bay. The eastern side of the peninsula is part of Botany Bay National Park, and Towra Point Nature Reserve is located on the western side of the suburb. History Kurnell is the place where Captain James Cook landed on 29 April 1770, making first contact with the original inhabitants of the area, the Gweagal people whilst navigating his way up the East Coast of Australia on Endeavour. Captain Cook along with his crew stayed at Kurnell for a period of eight days. During their visit they collected botanical specimens, mapped the area and tried to make contact (unsuccessfully) with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbonate Platform
A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits. Platform growth is mediated by sessile organisms whose skeletons build up the reef or by organisms (usually microbes) which induce carbonate precipitation through their metabolism. Therefore, carbonate platforms can not grow up everywhere: they are not present in places where limiting factors to the life of reef-building organisms exist. Such limiting factors are, among others: light, water temperature, transparency and pH-Value. For example, carbonate sedimentation along the Atlantic South American coasts takes place everywhere but at the mouth of the Amazon River, because of the intense turbidity of the water there. Spectacular examples of present-day carbonate platforms are the Bahama Banks under which the platform is roughly 8 km thick, the Yucatan Peninsula which is up to 2 km thick, the Florida platform, the platform on which the ...

Shack
A shack (or, in some areas, shanty) is a type of small shelter or dwelling, often primitive or rudimentary in design and construction. Unlike huts, shacks are constructed by hand using available materials; however, whereas huts are usually rural and made of natural materials (mud, rocks, sticks, etc.) shacks are generally composed of scavenged man-made materials like abandoned construction debris, repurposed consumer waste and other useful discarded objects that can be quickly acquired at little or no cost and fashioned into a small dwelling. Background In areas of high population density and high poverty, shacks are often the most prevalent form of housing; it is possible that up to a billion people worldwide live in shacks. Fire is a significant hazard in tight-knit shack settlements. Settlements composed mostly or entirely of shacks are known as slums or shanty towns. In Australian English ''shack'' can also refer to a small holiday house with limited conveniences, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Golden Plover
The American golden plover (''Pluvialis dominica''), is a medium-sized plover. The genus name is Latin and means relating to rain, from ''pluvia'', "rain". It was believed that golden plovers flocked when rain was imminent. The species name ''dominica'' refers to Santo Domingo, now Hispaniola, in the West Indies. American golden plover and picked up the spores while lining their nests. Then when the birds arrive in new places they molt, leaving behind the feathers and their precious cargo to start growing again at the other end of the world. Description Measurements: * Length: * Weight: * Wingspan: The breeding adult American golden plover has a black face, neck, breast, and belly, with a white crown and nape that extends to the side of the breast. The back is mottled black and white with pale, gold spots. The breeding female is similar, but with less black. When in , both sexes have grey-brown upperparts, pale grey-brown underparts, and a whitish eyebrow. The head is sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-necked Stint
The red-necked stint (''Calidris ruficollis'') is a small migratory wader. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ruficollis'' is from Latin ''rufus'', "red" and ''collum'', "neck". Description These birds are among the smallest of waders, very similar to the little stint, ''Calidris minuta'', with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It measures in length, in wingspan and in body mass. It can be distinguished from the western sandpiper and the semipalmated sandpiper in all plumages by its combination of a fine bill tip, unwebbed toes, and longer primary projection. The breeding adult has an unstreaked orange breast, bordered with dark markings below, and a white V on its back. In winter plumage identi ...

Ruddy Turnstone
The ruddy turnstone (''Arenaria interpres'') is a small cosmopolitan wading bird, one of two species of turnstone in the genus ''Arenaria''. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and is often known simply as turnstone. Taxonomy The ruddy turnstone was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa interpres''. The species is now placed together with the black turnstone in the genus '' Arenaria'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the ruddy turnstone as the type species. The genus name ''arenaria'' is from Latin ''arenarius'', "inhabiting s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plovers
Plovers ( , ) are a widely distributed group of wading birds belonging to the subfamily Charadriinae. Description There are about 66 species in the subfamily, most of them called "plover" or " dotterel". The closely related lapwing subfamily, Vanellinae, comprises about 20 species. Plovers are found throughout the world, with the exception of the Sahara and the polar regions, and are characterised by relatively short bills. They hunt by sight, rather than by feel as longer-billed waders like snipes do. They feed mainly on insects, worms or other invertebrates, depending on the habitat, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. Plovers engage in false brooding, a type of distraction display. Examples include pretending to change position or to sit on an imaginary nest site. Species list in taxonomic sequence The International Ornithological Committee (IOC) recognizes these 45 species of plovers and do ...

Cobbles
Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. Setts, also called Belgian blocks, are often casually referred to as "cobbles", although a sett is distinct from a cobblestone by being quarried or shaped to a regular form, whereas cobblestone is generally of a naturally occurring form and is less uniform in size. Use in roading Cobblestones are typically either set in sand or similar material, or are bound together with mortar. Paving with cobblestones allows a road to be heavily used all year long. It prevents the build-up of ruts often found in dirt roads. It has the additional advantage of immediately draining water, and not getting muddy in wet weather or dusty in dry weather. Shod horses are also able to get better traction on stone cobbles, pitches or setts than tarmac or asphalt. The fact that carriage wheels, horse hooves and even modern automobiles make a lot of noise when rolli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boulders
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

Tide Pool
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. Many of these pools exist as separate bodies of water only at low tide. Many tide pool habitats are home to especially adaptable animals that have engaged the attention of naturalists and marine biologists, as well as philosophical essayists: John Steinbeck wrote in '' The Log from the Sea of Cortez'', "It is advisable to look from the tide pool to the stars and then back to the tide pool." Zones from shallow to deep The rocky shoreline exhibits zonation as a feature of the shoreline. Tidal movements of water creates zonation patterns along rocky shores from high to low-tide. The area above the high-tide mark is the supralittoral zone which is virtually a terrestrial environment. The area around the high-tide mark is known as the intertidal fringe. Between the high and low-tide marks is the intertidal or littoral zone. Below the low-tide mark is the sublittoral or subt ...

Fracture (geology)
A fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces. A fracture will sometimes form a deep fissure or crevice in the rock. Fractures are commonly caused by stress exceeding the rock strength, causing the rock to lose cohesion along its weakest plane. Fractures can provide permeability for fluid movement, such as water or hydrocarbons. Highly fractured rocks can make good aquifers or hydrocarbon reservoirs, since they may possess both significant permeability and fracture porosity. Brittle deformation Fractures are forms of brittle deformation. There are two types of primary brittle deformation processes. Tensile fracturing results in ''joints''. ''Shear fractures'' are the first initial breaks resulting from shear forces exceeding the cohesive strength in that plane. After those two initial deformations, several other types of secondary brittle deformation can be observed, such as ''frictional slidi ...
