Argo logo

Argo is an observation system for the Earth's oceans that provides real-time data for use in climate, weather, oceanographic and fisheries research. The Argo array is comprised of over 3000 free-drifting profiling floats that measure the salinity and temperature of upper 2000 meters of the ocean. Once every 10 days, each float surfaces in order to take measurements and transmit them. The array allows, for the first time, the continuous monitoring of the temperature, salinity, and velocity of the upper ocean.

  • The Argo home page explains how Argo works, how to get Argo data or products that use the data, and the latest news about the array.
  • The Pacific Marine Environmental Laboratory (PMEL) provides estimates of recent changes in Upper Ocean Heat Content Anomaly from Argo floats, Expendable Bathythermographs (XBTs), and CTD (conductivity, temperature and depth) measurements. PMEL also maintains profiling float web site. focussing on data quality control.
  • The Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology in situ Observing Platform Support Centre (JCOMMOPS) operates the International Argo Information Centre.
