1. Argo Programme – activities in Japan – Keisuke Mizuno (JAMSTEC) Argo is a global array of 3,000 free-drifting profiling floats that measure temperature and salinity of the upper 2000 m of the ocean. Argo allows continuous monitoring of the global upper ocean, with all data being made open to public. Argo is the sum of national contributions, coordinated by an international Steering Team, and endorsed by the WMO and IOC/UNESCO.
