Coral bleaching is a phenomenon where symbiotic algae come out of the coral due to the abnormal rise in the sea water temperature or other reasons, often resulting in the death of the coral. The phenomenon is thought to have a great cause-and-effect relationship with climatic changes because it occurred at coral reefs all over the world, interlocking with displacement to the south of El Nino and Southern Oscillation which became the largest scale in marine observation history.

"Coral bleaching" is occurring in southeast Asia and the Great Barrier Reef. This is thought to be caused by increases in temperature and salinity, which causes the coral to reduce its symbiosis with photosynthetic protozoans. Past bleaching in the Mediterranean was attributed to a parasitic strain of Vibrio shiloi.

Coral reefs are very sensitive to their environment and are greatly affected by pollution. They are also impacted by climate change, which has been cited as a cause of coral bleaching.


What does bleaching of coral reefs mean?

Coral reef bleaching is the result of the die-off of certain coral. Coral reef bleaching is the whitening of diverse invertebrate taxa. Coral reef bleaching is caused by various anthropogenic and natural variations in the reef environment including sea temperature, solar irradiance, sedimentation, xenobiotics, subaerial exposure, inorganic nutrients, freshwater dilution, and epizootics.

What is choral bleaching?

This is a bit misleading because the word "coral" is misspelled "choral." Coral bleaching kills living coral organisms and is very prevalent in parts of the Carribbean. The coral appears pale white (or "bleached") instead of its normal gray-green-brown hues. Coral heads are actually made up of thousands of tiny, living organisms. Coral bleaching kills the coral and produces the white, bleached appearance. The coral can recover; however, it takes many, many years for coral to grow to a sizeable mass. Coral bleaching often kills the entire coral colony. Global warming is thought to contribute to coral bleaching: the problem in the Carribbean has worsened with just a one- or two-degree increase in water temperature.

What things are bleaching the coral at the Great Barrier Reef?

Many things are causing coral reef to get bleached. I think there are three main causes. For example, by just touching the coral with your hand or feet, kills the coral polyps. Also, overfishing kills it too. However, global warming is warming the water and not letting the coral reef or creatures of the reef survive. So, those are the ways that coral gets bleached! --Michelle from NJ...(6th gradeee)..........<3!

What are the advantages of bleach?

I am not aware that any scientist considers coral bleaching to be advantageous; bleaching indicates the death of symbiotic algae within the coral, leading to the death of the coral itself, leading to a greatly reduced oceanic biodiversity, which is a bad thing.
