Argo floats

Definition

Argo floats are autonomous drifting devices that collect oceanographic data, such as temperature and salinity, as they move with ocean currents. These floats provide valuable real-time information about the ocean's physical state, enabling better understanding of climate change, weather patterns, and marine ecosystems.

5 Must Know Facts For Your Next Test

1. Argo floats operate at various depths, typically drifting down to about 2,000 meters before ascending to the surface to transmit data via satellite.
2. The Argo program was initiated in the early 2000s and has deployed thousands of floats worldwide, contributing significantly to the global ocean observing system.
3. Data collected by Argo floats is crucial for improving climate models and predicting weather events, as they help scientists understand the role of oceans in climate regulation.
4. Each float is equipped with sensors that measure temperature and salinity, providing essential data that can be used for research on ocean circulation patterns.
5. Argo floats contribute to conservation efforts by helping monitor changes in ocean health, which is vital for protecting marine biodiversity and managing fisheries.
