One of the main dire results of world weather switch for coral reefs is the elevated frequency and severity of mass coral bleaching occasions. This quantity presents details at the motives and outcomes of coral bleaching for coral reef ecosystems, from the extent of person colonies to ecosystems and at diverse spatial scales, in addition to a close research of ways it may be detected and quantified. destiny situations in response to modelling efforts and the aptitude mechanisms of acclimatisation and version are reviewed. The even more critical coral bleaching occasions skilled on Caribbean coral reefs (compared with these of the Indo-Pacific) are mentioned, as are the diversities in bleaching susceptibility and restoration which were saw on smaller geographic scales.

Example text

It should have been a reference to the 1980 bleaching event. 3 Coral Bleaching in Space and Time 31 Fig. 5 Number of records of coral bleaching on the Great Barrier Reef Extensive in-situ and satellite temperature data over the past 15 years also suggest that there were at least two “near-bleaching” years when bleaching thresholds were approached and noticeable paling commenced at a number of sites. These years include 1995 when Michalek-Wagner and Willis (2001) noted a mild bleaching event at Orpheus Island and early 2005 when mild bleaching was reported for several reefs on the GBR.

The SOI may therefore be a poor direct indicator of ENSO events at a local or sub-regional scale even though it is possible that many of the GBR bleaching events are indirectly caused by ENSO-related anomalies. The reversals of normal ocean current directions, particularly in the equatorial Pacific during ENSO, events has a profound but indirect influence on local weather conditions. The nature and timing of the effects may be highly variable in different locations and from one event to another.

6. Do the observed periods of significant global bleaching correspond with the periodic occurrence of El Niño–Southern Oscillation (ENSO) events? 1 Early Bleaching Records (Pre-1982) The earliest confirmed record of reef-wide bleaching due to thermal stress is probably that of Yonge and Nicholls (1931). ) were observed to have lost their zooxanthellae and turned white. Some weeks later these corals were observed to be recovering their colouration, and histological inspection revealed that they had lost and then started to recover their zooxanthellae populations.
