Argo is an international fleet of underwater robotic instruments. The program collects real-time data that informs BOM's weather forecasts and climate predictions.
Cycle of an Argo float:
• Descends to drifting depth at 1000 m.
• Drifts for 8–10 days.
• Descends to profiling depth at 2000 m.
• Begins measuring temperature and salinity.
• Continues measuring on the ascent.
• Surfaces to transmit data via satellite.
• Starts next cycle.
