Mark's early warning about coral bleaching in the Florida Keys reminded me
that a spreadsheet has been developed for entering and partially analyzing
bleaching category data, specifically for the Caribbean. To use it one needs
to be able to identify corals to the genus or species and estimate the
extent of bleaching of each colony. The method has the advantage of giving
taxa and site-specific bleaching indices. It is available in the public
folder below along with a slide show that explains the method in more


The following papers present examples of a coordinated effort to study
bleaching using this method in a large number of sites through the
coordinated efforts of the authors.
