The Jellyfish Database Initiative (JeDI) is a scientifically-coordinated global database dedicated to gelatinous zooplankton (members of the Cnidaria, Ctenophora and Thaliacea) and associated environmental data. The open-access database was designed for all researchers, media, and public to use as a current and future research tool. The database holds 476,000 quantitative, categorical, presence-absence and presence only records of gelatinous zooplankton spanning the past four centuries (1790-2011) assembled from a variety of published and unpublished sources. Gelatinous zooplankton data are reported to species level, where identified, but taxonomic information on phylum, family and order are reported for all records.
A global database of mangrove forest cover at high spatial and temporal resolutions that has been used to monitor mangrove cover at the global, national and protected area scales. Several databases including the Global Forest Change database, the Terrestrial Ecosystems of the World database, and the Mangrove Forests of the World database were used to extract the mangrove forest cover.
