Argo Floats

Definition

Argo floats are autonomous, drifting buoys that collect and transmit oceanographic data from the upper layers of the ocean. They provide critical information on temperature, salinity, and currents, contributing significantly to our understanding of ocean dynamics and climate change over time. The data gathered by these floats is essential for studying ocean circulation patterns and improving weather forecasting models.

5 Must Know Facts For Your Next Test

1. Argo floats descend to depths of about 2,000 meters before rising to the surface to collect data, making them capable of gathering information from both the surface and subsurface layers of the ocean.
2. There are over 4,000 Argo floats deployed worldwide, providing near real-time data that helps scientists monitor changes in ocean temperature and salinity.
3. The program began in the early 2000s and has significantly enhanced our ability to observe the global oceans, contributing to advancements in climate science.
4. Data from Argo floats is made publicly available and is used by researchers globally for a variety of applications, including climate modeling and oceanographic research.
5. Argo floats have been instrumental in identifying long-term trends in ocean warming, which is crucial for understanding climate change and its impacts on marine ecosystems.
