This page contains links to the two components of a new historical coral bleaching database developed by my research group and described in Donner et al. 2017. We are currently working on version 2 of the database, which should include data through the end of 2016. If you have past bleaching observations which you would be willing to share in this public database, please get in touch.
1. Observational Bleaching Database
This database is an expansion of the voluntary Reefbase database of bleaching observations developed through outreach to the coral reef research and monitoring community and from observations available in the literature. Version 1.0 contains observations through 2010. A spreadsheet in .xlsx format lists each individual bleaching observation and a database legend (see “README”).
2. Interpolated Bleaching Probability Database
The probability of bleaching occurrence in a given year between 1985 and 2010 was spatially modelled across the world’s warmwater coral reefs at 0.04° X 0.04° latitude-longitude resolution using indicator kriging. 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. Please consult the manuscript and the authors before employing this data.
