The Great Barrier Reef Marine Park Authority considers the greatest threat to the Great Barrier Reef to be climate change, causing ocean warming which increases coral bleaching. [ 64 ] [ 65 ] Mass coral bleaching events due to marine heatwaves occurred in the summers of 1998, 2002, 2006, 2016, 2017 and 2020, [ 66 ] [ 13 ] [ 67 ] and coral ...
This contributes to the conditions which allow the Great Barrier Reef to thrive, keeping the east coast around 18 °C year round instead of dropping to 12 °C in the winter. [4] The current is very low in nutrients but remains important for the marine ecosystem. The EAC transfers heat from the tropics to the mid-latitude water and atmosphere. [5]
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals form multiple symbiotic relationships with the organisms around them. [7]
Canton Island typifies the isolated coral atolls dotting the Pacific Ocean. The Structure and Distribution of Coral Reefs, Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836, was published in 1842 as Charles Darwin's first monograph, and set out his theory of the formation of coral reefs and atolls.
The Great Barrier Reef is the world's largest coral reef system, composed of roughly 3,000 individual reefs and 900 islands stretching for 2,600 kilometres (1,616 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia.
It describes the organisms and ecosystems of Australia's Great Barrier Reef, and the biological, chemical and physical processes that influence them. Issues discussed include climate change, coral bleaching, coral disease and coral reef fishing. The book includes a field guide to help people identify the common animals and plants on the reef.
A major coral bleaching event took place on this part of the Great Barrier Reef. The Great Barrier Reef is the world's largest reef systems, stretching along the East coast of Australia from the northern tip down at Cape York to the town of Bundaberg, [1] [2] is composed of roughly 2,900 individual reefs and 940 islands and cays that stretch for 2,300 kilometres (1,616 mi) and cover an area of ...
The islands, cays and reefs of the Great Barrier Reef are not part of the territory, belonging to Queensland instead. The outer edge of the Great Barrier Reef is the boundary between Queensland and the Coral Sea Islands Territory. The territory is a possession or external territory of Australia, administered from Canberra.
