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.

Australia – December 16th, 2012

Fires can be seen near the coast of Queensland, Australia, releasing plumes of smoke that blow eastward over the Coral Sea. Visible offshore is the Great Barrier Reef, the world’s largest coral reef system. It is 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).

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.

Sediments and Barrier Reef by Cape York Peninsula, Australia

Australia - June 20th, 2011

Cape York Peninsula is a large remote peninsula located in Far North Queensland at the tip of the state of Queensland, Australia. The west coast borders the Gulf of Carpentaria and the east coast borders the Coral Sea.

Here, sediments can be seen along the peninsula’s west coast, in the Gulf of Carpentaria. The east coast bordering the Coral Sea, however, is lined by vertebra-like segments of the Great Barrier Reef.
