Around the time POGO was being started, the Argo programme was also beginning. One of the first crusades of POGO was to throw the collective weight of its members behind the world expansion of Argo. A collaboration among 50 research and operational agencies from 26 countries, Argo now has charge of more than 3,500 floats around the world’s oceans. Because the members of POGO are directors with the power to commit resources and influence decision makers, a resolution to accord full support to Argo had immediate effect, and the distribution of floats around the world ocean improved rapidly. Argo is now part of the Global Ocean Observing System (GOOS).
