This page was established to house the historical coral bleaching database developed by my research group and described in Donner et al. 2017.
Version 2 of the database, which includes data through the end of 2017, is now available via the data storing service Zenodo. Please see the Zenodo page to access the data.
There are two components to the database. The first component is a spreadsheet listing raw bleaching observations from 1963 to 2017, developed through outreach to the coral reef research and monitoring community and from observations available in the literature. The spreadsheet in .xlsx format lists each individual bleaching observation and a database legend (see “README” sheet).
The second component is the annual probability of bleaching occurrence in a given year between 1985 and 2017 at 0.05° X 0.05° latitude-longitude resolution for all warmwater reef cells, developed via spatial modelling. Probabilities were not estimated for years in which there were no reports or the modeled semi-variograms failed to converge due to the low number of bleaching observations that year. Annual gridded maps of the bleaching probabilities are provided in .geotiff format within the zip file.
