🔎 Spotting a float in the ocean is not easy. How to do?

🌊 During its deployment, the profiling float sinks to a depth (for example 1000 meters) and drifts with the ocean currents for 9 days. Then, the float sinks further to the depth of 2000 meters, before starting to raise the water column by making measurements as it rises.

📡When the float reaches the surface, it transmits its position and oceanographic measurements by satellite to the Argo terrestrial data centres. After transmission, the float descends and repeats the cycle.
