How Argo Floats Work

SHARE THIS:

Argo floats sink to depths of 2,000 meters, drift with ocean currents for several days, rise to the surface taking measurements of water temperature and salinity along the way, and then transmit data back to shore via satellite before descending again.  (Animation by Tim Silva, Woods Hole Oceanographic Institution)
