Argo is a global array of 3,000 autonomous profiling floats measuring in real time and every 10 days temperature and salinity throughout the deep global oceans, down to 2,000 meters. Argo is a real revolution in oceanography history. Argo is the first-ever global, in-situ ocean-observing network in the history of oceanography, providing an essential complement to satellite systems to observe, to understand and to predict ocean and global climate changes.
