One is the Great Barrier Reef off the coast of Australia. The icon of the natural world is bigger than the whole of the UK and is composed of over 2,900 individual reefs and 900 islands. However, when the average temperature of the ocean water in which a coral lives is raised by just a degree or two, the coral become stressed and eject their algae tenants. The Great Barrier Reef Marine Park Authority has started the second phase of its survey to assess the impact of 2016's bleaching. 2009). The incredible Coral Sea wilderness, which stretches for roughly 1,400 miles over an area of roughly 133,00sq/m, is said to have finally succumbed to bleaching. This triggers a slow and steady starving of the coral if they do not accept zooxanthellae back into their polyps in time.

The reef lies off the coast of Queensland in Australia and can be seen from outer space. The southern sector was spared in both years. According to the Australian Institute of Marine Science, the most recent (2017-18) survey of Moore reef showed 0-5% coral cover, compared with about 20% in the 1980’s.

The sprawling Coral Sea reef is larger than the UK and home to over 900 islands and 1,625 species of fish. It is the cycle of warm and cold temperatures in the ocean surface along the equatorial Pacific, driven by high air pressure in the western Pacific Ocean and low air pressure in the eastern Pacific Ocean. T… Victoria Nielsen vic_nielsen news.com.au … The current reef is about 6,000 to 8,000 years old, forming after the last ice age began. Scientists at Lizard Island’s research centre called it the worst bleaching since 2002. The ejection of algae by coral is the process in which we call coral bleaching, as it removes the colorful algae from corals, leaving their stark carbonate structure colorless. The Great Barrier Reef Marine Park Authority (GBRMPA) says 2016 has seen the worst bleaching on record. In exchange for a safe place for the zooxanthellae (algae) to live, the algae photosynthesize energy and provide such energy to the corals. The Great Barrier Reef, which stretches for 1,400 miles along Australia's coast, suffered an unprecedented coral bleaching event in the summer of 2016, followed by another bleaching event in 2017.
