The Tuna Atlas VRE is a tool to handle public domain data from various (Tuna) Regional Fisheries Management Organizations (T-RFMOs). Data include catches, fishing efforts and size frequencies of the species managed by the five tuna RFMOs: CCSBT- Commission for the Conservation of Southern Bluefin Tuna IATTC- Inter-American Tropical Tuna Commission ICCAT- International Commission for the Conservation of Atlantic Tunas IOTC- Indian Ocean Tuna Commission WCPFC - Western and Central Pacific Fisheries Commission Tuna Atlas provides services to discover the available datasets at regional and global levels, extract them in several formats widely used by the scientific community (e.g. CSV, NetCDF, SDMX) and visualize them in an interactive web-viewer of indicators and maps. It also includes tools for the users to generate their own Tuna atlas by applying own processing (e.g. applying specific choices for scientific corrections) on the tuna RFMOs data.
