Jellyfish Database Initiative (JeDI)

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of gelatinous zooplankton spanning the past four centuries (1790-2011) assembled from a variety of published and unpublished sources.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

The greatest concentration of data in the JeDI database has been recorded in the mid-latitudes of the Northern Hemisphere.
