Scientists have had a great swim above the coral Source: Author Woody Spark Scientists have had a great swim above the coral Source: Author Woody Spark Source: Author Woody Spark A super large coral discovered by scientists on the Great Barrier Reef in Australia This huge coral is the widest and sixth tallest coral on the Great Barrier Reef Corals are structures composed of small marine animals and calcium carbonate The new coral was discovered by snorkelers off the coast of Orpheus Island, part of the Palm Islands in Queensland, Australia Adam Smith of the Queensland Coral Reef Ecological Center in Australia and colleagues studied the large coral and found that it is hemispherical, 5. Based on the calculation of coral growth rate and annual sea surface temperature, the author estimates that the appearance of large corals was 421 to 438 years ago, earlier than the earliest Europeans discovered and settled in Australia After reviewing the environmental events of the past 450 years, it is found that the great coral may have experienced as many as 80 major hurricanes and have been exposed to invasive species, coral bleaching events, low tides and human activities for hundreds of years Researchers found that the large corals are in good health, with a 70% coverage of live corals, and the rest are green perforated sponges, turf seaweeds and green algae The author recommends close monitoring of this rare and extremely resilient large coral, and believes that it may need to be restored, so as to minimize future climate change, deterioration of water quality, overfishing and coastal development.
