Breaksea Island (Western Australia)
Breaksea Island in King George Sound in the Great Southern region of Western Australia is south-east of Albany. Description The island was declared a nature reserve in 1969) managed by the Department of Environment and Conservation; its reserve number is 27614. The island is also registered as a national estate. The island is in area, in length, and at its widest part. The closest island is Michaelmas Island, located north of Breaksea Island. History The island was named by George Vancouver during his expedition in 1791. While in the area he also took possession of the lands for England. He named the island after its beaten appearance and the protection it offered to the landward side from the south-westerly winds. In early April 1827, the island was visited by Major Edmund Lockyer, who found that the island, which had been previously assumed to be bare rock, actually featured between eight and ten acres of soil. He also noted the presence of seals, little penguins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for " Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing br ...

Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel ...

HMAS Perth (D38)
HMAS ''Perth'' (D 38) was the lead ship of the guided missile destroyers operated by the Royal Australian Navy (RAN). Built in the United States to a modified version of the ''Charles F. Adams'' design, ''Perth'' entered service with the RAN in 1965. The destroyer made three deployments to the Vietnam War, earning a RAN battle honour and two United States Navy commendations for her service. The majority of the ship's career was spent on training exercises and goodwill visits to other nations, with one deployment as far as the Mediterranean. ''Perth'' was decommissioned in 1999, and sunk as a dive wreck off the coast of Western Australia in 2001. Design and construction ''Perth'' was the lead ship of three guided missile destroyers built for the RAN.Cassells, ''The Destroyers'', p. 81 Based on the United States Navy's , ''Perth'' had a displacement of 3,370 tons at standard load, and 4,618 tons at full load, a length of overall and between perpendiculars, a beam o ...

HMS Investigator (1798)
HMS ''Investigator'' was the mercantile ''Fram'', launched in 1795, which the Royal Navy purchased in 1798 and renamed HMS ''Xenophon'', and then in 1801 converted to a survey ship under the name HMS ''Investigator''. In 1802, under the command of Matthew Flinders, she was the first ship to circumnavigate Australia. The Navy sold her in 1810 and she returned to mercantile service under the name ''Xenophon''. She was probably broken up c.1872. Background ''Fram'' was built in Sunderland as a collier. She operated off the north-east coast of England before the Royal Navy purchased her in 1798. Pitcher, of Northfield refitted her between 27 April and 24 May 1798. She then went to Deptford Dockyard on 6 August. The Navy armed her with 22 carronades to serve as an escort vessel, and renamed her HMS ''Xenophon''. Commander George Sayer commissioned ''Xenophon'' as an armed ship for the North Sea. In 1799 he brought the Irish rebel James Napper Tandy and some of his associates as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matthew Flinders
Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French governor at Isle de France (Mauritius). Although Britain and France were at war, Flinders thought the scientific nature of his work would ensure safe passage, but he remained under arrest for more than six years. I ...

George Vancouver
Captain George Vancouver (22 June 1757 – 10 May 1798) was a British Royal Navy officer best known for his 1791–1795 expedition, which explored and charted North America's northwestern Pacific Coast regions, including the coasts of what are now the Canadian province of British Columbia as well as the US states of Alaska, Washington and Oregon. He also explored the Hawaiian Islands and the southwest coast of Australia. Vancouver Island, the city of Vancouver in British Columbia, Vancouver, Washington in the United States, Mount Vancouver on the Canadian–US border between Yukon and Alaska, and New Zealand's fourth-highest mountain, also Mount Vancouver, are all named after him.

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date bac ...
