Great Barrier Reef Parallel to Australia Coast – May 4th, 2013

Australia – May 4th, 2013

The Great Barrier Reef stretches 2,300 kilometres along the Queensland coast and includes over 2,900 reefs, and around 940 islands and cays.
Although the reef was thought to be well-protected, scientists have discovered that poor fishing practices, pollution and coral bleaching exacerbated by increased sea temperatures due to global warming are all seriously threatening the reef’s future.

Close-up

Visible in the Coral Sea, off the coast of Queensland in northeast Australia, is the Great Barrier Reef. It is the world’s largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching for over 2,600 kilometres (1,600 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).

The reef structure is composed of and built by billions of tiny organisms, known as coral polyps. A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as fishing and tourism. Other environmental pressures on the reef and its ecosystem include runoff, climate change accompanied by mass coral bleaching, and cyclic population outbreaks of the crown-of-thorns starfish.

Climate change, pollution, crown-of-thorns starfish and fishing are the primary threats to the health of this reef system. Other threats include shipping accidents, oil spills, and tropical cyclones. Skeletal Eroding Band, a disease of bony corals caused by the protozoan Halofolliculina corallasia, affects 31 coral species.

Australia - May 2nd, 2011

On the left side of this image, tan sediments from the Styx River color the waters of Broad Sound. It is a large bay in the state of Queensland, on the east coast of Australia.

Moving to the upper right part of the image, numerous islands and atolls composing part of the Great Barrier Reef can be observed. They appear as light blue shapes dotted across the dark blue ocean waters.

Australia - January 24th, 2011

Despite some scattered clouds, part of the Great Barrier Reef is visible off the coast of Queensland, Australia. The parts of the reef appear teal in color and lie parallel to the coast.

Moving back to the shoreline, tan sediments from the Styx River can be seen flowing into Broad Sound. The Sound is a large bay on the east coast of Australia. The Torilla Peninsula forms the eastern side of the bay; Shoalwater Bay is on the other side of the peninsula.

Australia - March 5th, 2010

A stretch of the Great Barrier Reef is visible here, in the Coral Sea off the coast of Queensland, Australia. It is the world’s largest reef system, composed of over 2,900 individual reefs and 900 islands stretching for over 2,600 kilometres (1,600 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).

The Great Barrier Reef World Heritage Area has been divided into 70 bioregions, of which 30 are reef bioregions. In the northern part of the Great Barrier Reef, ribbon reefs and deltaic reefs have formed; these structures are not found in the rest of the reef system. There are no atolls in the system, and reefs attached to the mainland are rare.
