The distribution of 3,325 ARGO drifters (buoys) in the world’s oceans at 0605 UTC on March 22, 2009—the data from these buoys are updated in almost real time from satellite observations. Each drifter collects data on temperature and salinity to 2000 m depth, and their movements indicate the direction and strength of ocean currents—important information for predicting weather. The ARGO project is a partnership of 44 countries. Viewing of the ARGO data is facilitated by a GIS viewer.
