    Argo Canada

    Argo is a global in situ ocean climate monitoring system consisting in an array of over 4,000 free-drifting floats that collect data on ocean temperature and salinity, and sometimes oxygen, in the upper 2000 m of the ocean. It is an international effort, with more than 30 nations contributing...
