Ralphs Bay
Ralphs Bay is a body of water in south-east Tasmania, Australia. It is semi-enclosed by the Tranmere / Rokeby peninsula and the South Arm peninsula. Sea access to the bay is from the River Derwent. Ralphs Bay is a shallow, windy bay, situated on the south-east of the Derwent Estuary, about 12 kilometres from the south-east of Hobart in Tasmania, Australia. The bay is sheltered by the low, grassy hills of Droughty Point to the north-west and the spit of South Arm and Opossum Bay to the south-west. Ecology The red-necked stint migrates from Siberia every year and most of the birds, which do that, find themselves in Ralphs Bay. It is also an important area for the spotted handfish. They are critically endangered and, because of the pollution in the River Derwent, live in majority at Ralphs Bay and its surrounding waters. The bay is part of the South Arm Important Bird Area (IBA), identified as such by BirdLife International because of its importance for the conservati ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaches Of Tasmania
A beach is a landform alongside a body of water which consists of loose particles. The particles composing a beach are typically made from rock, such as sand, gravel, shingle, pebbles, etc., or biological sources, such as mollusc shells or coralline algae. Sediments settle in different densities and structures, depending on the local wave action and weather, creating different textures, colors and gradients or layers of material. Though some beaches form on inland freshwater locations such as lakes and rivers, most beaches are in coastal areas where wave or current action deposits and reworks sediments. Erosion and changing of beach geologies happens through natural processes, like wave action and extreme weather events. Where wind conditions are correct, beaches can be backed by coastal dunes which offer protection and regeneration for the beach. However, these natural forces have become more extreme due to climate change, permanently altering beaches at very rap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bays Of Tasmania
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Marina
A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. The word ''marina'' may also refer to an inland wharf on a river or canal that is used exclusively by non-industrial pleasure craft such as canal narrowboats. Emplacement Marinas may be located along the banks of rivers connecting to lakes or seas and may be inland. They are also located on coastal harbors (natural or man made) or coastal lagoons, either as stand alone facilities or within a port complex. History In the 19th century, the few existing pleasure craft shared the same facilities as trading and fishing vessels. The marina appeared in the 20th century with the popularization of yachting. Facilities and services A marina may have refuelling, washing and repair facilities, marine and boat chandlers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Lauderdale, Tasmania
Lauderdale is a town on the outskirts of Hobart, capital of Tasmania, Australia. The population of Lauderdale is approximately 2,592 (2021 census). It is in the local government area of City of Clarence. The town is situated on the eastern side of a thin isthmus that connects the South Arm Peninsula to the mainland. It faces Ralphs Bay, and the majority of Lauderdale's population live along Roches Beach, which faces Frederick Henry Bay. Along with nearby Seven Mile Beach, it is a popular residential area for people working in the Hobart CBD. Lauderdale/Roches Beach is overlooked by Single Hill, which is just to the North. Beyond Single Hill is the town of Seven Mile Beach. The view from Single Hill gives a clear view of the town of Lauderdale. The view also shows the nearby ABC radio transmitter mast. The Ralphs Bay side of Lauderdale reveals a sharp gradient in the bay where the water changes colour. This change can be especially noticeable when driving along the main road fr ...

Colonial Ship King George
Colonial Ship ''King George'' was the first ship, by virtue of having three masts, built in the colony of Sydney, New South Wales. ''King George'' was described variously as a square-rigged ship and a three-masted schooner, known in America during the later 19th century as a "tern". The confusion is due to her being modeled on the Baltimore-built three-masted schooners that had sail plans which resembled the square-rigged ships. These ships came into use in the later half of the 18th century, and would have been known to James Underwood (shipbuilder), James Underwood, the shipyard builder. Their distinctive sail plan feature was in having the extremely large fore and main courses, and only the fore and main topsails, with the mizzen mast rigged with the mainsail and main-topsail in place of the spanker, a plan based on the two-masted Boston pilot schooner that eventually evolved into the famed Baltimore clippers in the 1830s. The fore and staysail booms were omitted to allow stow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Knopwood
Robert Knopwood (2 June 1763 – 18 September 1838) was an early clergyman and diarist in Australia. Knopwood was the third child and only surviving son of Robert Knopwood (from a wealthy Norfolk family) and his wife Elizabeth, ''née'' Barton of Threxton, Norfolk, England. Knopwood was educated at Gonville and Caius College, Cambridge, and graduated B.A. in 1786, M.A. in 1790. Knopwood was ordained deacon in December 1788 and priest a year later. Having inherited a fortune as a young man, he became a member of the gambling set associated with the Prince Regent and quickly lost his money. He obtained a position as chaplain in the navy, and was appointed to Colonel Collins's expedition which, after the failure of the Port Phillip settlement, landed on the site of Hobart on 19 February 1804.

East Asian – Australasian Flyway
East or Orient is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'. ''Ēostre'', a Germanic goddess of dawn, might have been a personificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
