Jellyfish Database Initiative (JeDI)

Leave a commentEcological, Zooplankton , ,

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of gelatinous zooplankton spanning the past four centuries (1790-2011) assembled from a variety of published and unpublished sources.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.
