Argo is an international fleet of underwater robotic instruments.
The program collects real-time data that informs the Bureau's weather and climate services.
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 ascent.
• Transmits data via satellite.
• Starts next cycle.
