The great BarrierA great barrier
Over the reef
It is a cultural inheritance, it is a nature inspired. It' s bigger than the Great Wall of China and the only creature on the planet that can be seen from outerspace. Situated 3000 km (1800 miles) almost alongside the Queensland coastline, near the southerly seaside city of Bundaberg, past the north tip of Cape York.
Situated between 15 and 150 kilometers off the coast and about 65 kilometers in some parts, the dive site is a collection of vibrant, bright corals that offer scuba diving the most amazing marine life you can imagine. It is a nesting area for Antarctic migratory bumpback cetaceans and is also the home of some threatened fish such as the dugong (manatee) and the large green sea turtle.
Due to its unspoilt beauties, both below and above the sea level, the island has become one of the most coveted travel destination in the world.
The Great Barrier Reef
The eastern seaboard of Australia seems to be in the midst of a huge opaque world. World' s biggest live building, the Great Barrier Reef, is a pointed, live rock face stretching over more than two thousand kilometres of island and secluded cliffs between the Queensland coastline and the west Pacific Ocean rim.
Great Barrier Reef is like an submarine town whose structures are vibrant, with tens of hundreds of millions of small living beings whose lifestyles are closely allied. It' s as varied as a rain forest, a tessellation of more than 70 different habitat forms with literally a thousand people.
Up to 100 different species of corals can take up one hectare of sea. Molecules by molecules, corals slowly remove carbonated limestone from the ambient waters to create tiny rocky mugs around each animal's tender tentacle canopy. While some corals are lonely, most are constructed with several hundred, sometimes even thousand, individuals connected to create a unique hill of corals, plates or a group of spars.
It provides nourishment and protection for tens of other lifeforms. The most part of the marine environment is recognised as being coralline, but much of the design is made up of rapidly expanding, crusting reedweed. Cementation of shell, sandy and calcareous plate cements.
It is home to more than 4000 species of molluscs, from nudibranches to mammals. Turtle species migrate several thousand nautical miles in the open ocean to spawn and nest on the sand shores of some of the Barrier Refs.
Over the years they will cover several thousand kilometres and finally start laying their own cubs. Founded in 1975 as a Nationalpark, the Great Barrier Reef was declared a World Heritage Site six years later. Great Barrier Reef seems to be about 20,000 years old, but the geologist using drilling technology has found indications of old coral that is half a million years old.
