Coral Bleaching: Patterns, Processes, Causes and by Madeleine J. H. van Oppen, Janice M. Lough

By Madeleine J. H. van Oppen, Janice M. Lough

One of the main dire results of worldwide weather switch for coral reefs is the elevated frequency and severity of mass coral bleaching occasions. This quantity presents details at the factors and results of coral bleaching for coral reef ecosystems, from the extent of person colonies to ecosystems and at various spatial scales, in addition to an in depth research of the way it may be detected and quantified. destiny eventualities in accordance with 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 variations in bleaching susceptibility and restoration which were saw on smaller geographic scales.

This would explain the observed inshore–offshore bleaching pattern during major bleaching events. El Niño weather patterns operate at regional scales and affect reef provinces only when they coincide with the regional summer. The GBR probably avoided a major bleaching event in 2005 only because ocean current anomalies returned to normal just before the austral summer. Despite its limitation, the database of bleaching records in ReefBase is highly valuable for quantifying major bleaching events.

3 Coral Bleaching in Space and Time 23 Coffroth et al. (1990), Williams and Bunkely-Williams (1990), Glynn (1991, 1993), and Goreau and Hayes (1994) have compiled records of much earlier mass coral mortality, dating back to 1876. These earlier reports provide details for specific sites in terms of the pattern and extent of mortality and the probable causes. g. aerial exposure, freshwater, “dark water”) are most often used to explain the mortality and in these cases there is no firm evidence to suggest that the cause of the mortality was high temperatures and that corals had bleached prior to dying.
