Stretching more than 2,000 km (1,200 miles) along the Queensland coast, the Great Barrier Reef, was inscribed on the World Heritage List in October 1981. One of Australia’s greatest assets is the magnificent reef which runs along virtually the entire coast of Queensland. Considered one of the world’s natural wonders, it is the most extensive reef system and the biggest structure made by living organisms on Earth. In the north, the reef is virtually continuous and is located only 50 km (30 miles) from the shore. In the south, individual reefs are more common, and in some places up to 300 km (190 miles) offshore. The Landsat 7 image shown here depicts southern parts of the reef system. Hundreds of islands dot the reef area. About twenty of them have resort facilities, but it is possible to camp on many others.
This image was acquired by Landsat 7’s Enhanced Thematic Mapper plus (ETM+) sensor on August 14, 1999. This is a natural color composite image made using red, green, and blue wavelengths (ETM+ bands 3, 2, & 1).
