The international Argo programme was launched in 1999 as a pilot project endorsed by the World Meteorological Organisation’s Climate Research Programme, GOOS and the Intergovernmental Oceanographic Commission. Argo is a global network of more than 3500 autonomous instruments, deployed over the world ocean, that report subsurface ocean properties to a wide range of users via satellite transmission links to data centres.
