	Great Barrier Reef @ nationalgeographic.com (Site not responding. Last check: 2007-10-07)
		Fringing reefs grow outward from the mainland’s shores, but more often they are found surrounding the region’s 618 continental, or high, islands, which were mountains and hills along Australia’s Ice Age coast before the glaciers melted and raised sea levels; the Aborigines’ legends of ancient generations walking out to those islands are true.
		A coral reef is made of “squillions” of coral colonies plus other limestone depositing organisms, growing on and among the skeletons of their predecessors, and the sands and silts derived from them.
		On the Great Barrier Reef, depending on where it grows, a reef can be either a ribbon reef (on the continental shelf edge), a platform reef (on the shelf), or a fringing reef (along the continental islands and mainland).

	Great Barrier Reef - MSN Encarta
		In 1975 the Great Barrier Reef Marine Park was established as the largest marine protected area in the world (though it was overtaken in size by the Northwestern Hawaiian Islands Marine National Monument in 2006).
		A barrier reef lies parallel to a coastline and is always separated from the shore by a wide lagoon.
		The growth of the Great Barrier Reef was subsequently interrupted by global changes in sea level and temperature during periods of glaciation, when more of the planet’s water was frozen in glaciers due to global cooling (see Ice Ages).

	Great Barrier Reef - Wikipedia, the free encyclopedia
		Unlike most reef environments worldwide, the Great Barrier Reef is the only one where the water catchment area is home to industrialised urban areas and where extensive areas of coastal lands and rangelands have been used for agricultural and pastoral purposes.
		Due to the range of human uses made of the water catchment area adjacent to the Great Barrier Reef some 400 of the 3000 reefs are within a risk zone where water quality has declined owing to sediment and chemical runoff from farming, and to loss of coastal wetlands which are a natural filter.
		Many of the corals of the Great Barrier Reef are currently living at the upper edge of their temperature tolerance, as demonstrated in the coral bleaching events of the summers of 1998, 2002 and most recently 2006.

	Discover Australia: Great Barrier Reef
		The Great Barrier Reef was proclaimed a marine park in 1975 and a management programme was undertaken to balance the interests of scientists, tourists and fishing enthusiasts, and to preserve the reef for future generations.
		The Great Barrier Reef is not one single entity but consists of more than 3000 individual reefs of various shapes and kinds...the term is sometimes used loosely to refer not only to the Reef itself but to the whole area, including the islands which are such a feature of the region.
		Reef walking is the most fantastic way to learn about marine life, especially if you have a naturalist on tap to help you identify the various inhabitants and their behavioural patterns.

	Great Barrier Reef -- WWF-Australia
		The reef is immensely diverse with 1,500 species of fish, 359 types of hard coral, one third of the world's soft corals, 175 bird species, six of the world's seven species of threatened marine turtle and more than 30 species of marine mammals including vulnerable dugongs.
		Reef industries, which are reliant on a healthy environment in which to operate, contributed approximately $5.8 billion to the Australian economy in 2004 and employed about 63,000 people.
		Not only is the reef subject to high levels of fishing pressure, other fishing practices such as seafloor trawling for prawns are still permitted in over half of the marine park, resulting in untargeted fish capture (by-catch) and destruction of the seafloor.

		CULTURAL HERITAGE The Great Barrier Reef, and in particular the northern sector, is important in the historic and contemporary culture of the Aboriginal and Torres Strait Islander groups of the coastal areas of north-east Australia.
		The arrangement recognises that the islands, reefs and waters of the area are a continuum and that they should be managed on a complementary basis.

		There are plenty of places from where you can explore the Great Barrier Reef, and whether you travel to the outer reef or visit some of the other reefs and Islands nearer the coast you are sure to be satisfied.
		The reef is called the 'Barrier' Reef because it is an outer reef, situated along the Australian continental shelf with the channel between the coastline and the reef reaching a depth of about 60m.
		To the south of the reef are a selection of continental islands including Dunk Island, Great Keppel Island, Hinchinbrook Island and several of the Whitsundays.

	Great Barrier Reef - Crystalinks
		The Great Barrier Reef, off Australia's east coast, is one of the wonders of the natural world.
		The corals which make up the various reefs and cays, and which are the base for this variety of sea and animal life, consist of individual coral polyps; tiny live creatures that join together to form colonies.
		Most of the Reef is part of the Great Barrier Reef Marine Park and various parts of it are protected in certain ways - for example, fishing is restricted in some areas, particular animals - like whales, dolphins, green turtles and dugong - are protected.

		The reef's massive structure is formed from coral polyps, tiny animals that live in colonies; when coral polyps die, they leave behind a hard, stony, branching structure made of limestone.
		There are coral reefs off the eastern coast of Africa, off the southern coast of India, in the Red Sea, and off the coasts of northeast and northwest Australia and on to Polynesia.
		Major threats to coral reefs are water pollution (from sewage and agricultural runoff), dredging off the coast, careless collecting of coral specimens, and sedimentation (when silt or sand from construction or mining projects muddies the waters of a reef and kills coral, which needs light to live).

	Coral Facts :: Great Barrier Reef
		Most modern reefs have formed on hard surfaces in the ocean, such as a base of an old reef that died during a period when sea level was lower, or the edge of a rocky island.
		The theories on how coral reefs form were first put forward by Charles Darwin (of The Origin of Species fame) who proposed that atolls form around the edges of high volcanic islands that gradually submerge beneath the sea with changes in sea level or subsidence of the land.
		The Crown-of-Thorns Seastar was once an animal of great controversy causing terrible damage to the coral reefs of the Great Barrier Reef.

	Great Barrier Reef
		It was just a tiny tiny fraction of the Great Barrier Reef - the Eighth Wonder of the World extends over 2000 km along the Queensland coast, ranging from fringing coastal reefs to lagoons, outer reefs and then to the open ocean, and includes biological diversity at ecosystem, community, species and genetic levels.
		The reef is closely guarded by the Australian government through the GBRMPA, which acts as a steward of all aspects of the reef environment, from water quality to aquaculture to coral bleaching issues.
		The reef is very fragile, despite its age and vastness; human activity is damaging to the reef, so when we were out there we were asked to not touch the coral and not 'souvenir' anything, lest the ship loses its permit.

		Individual reefs are of two main types: platform reefs formed from radial growths, and wall reefs resulting from elongated growths, often in areas of strong water currents.
		Each reef has a thin layer of living coral capping a structure made up mainly of calcareous sand and rubble from the breakdown and consolidation of coral and other skeletal material.
		Many of the present reef areas were once hills on a former coastal plain, and these became islands when the water level rose after the last Ice Age, to be colonised by coral polyps.
