The GCDD is the result of a collaboration between UNEP-WCMC and NOAA NMFS. The project aims to collate information on the global distribution of coral diseases, in order to contribute to the understanding of coral disease prevalence. The GCDD is a compilation of information from scientific literature gathered before 2007 (archive data), as well as new contributions from users. The content of the database is being continually updated by users, creating a sustainable platform for the dissemination of coral disease data.
