Argo (ocean profiling floats)

Argo is a global network of autonomous floating devices used to monitor the ocean’s conditions. These floats drift with ocean currents, periodically sinking and then ascending to measure temperature, salinity, and other water properties at various depths. This data helps scientists track changes in climate, ocean currents, and marine ecosystems, providing essential information for weather forecasting, climate models, and environmental research. The process is automated, allowing continuous, widespread observation of the world’s oceans without the need for ships or manual data collection.
