Argo Data 1999–2019: Two Million Temperature-Salinity Profiles and Subsurface Velocity Observations From a Global Array of Profiling Floats
Overview
Paper Summary
The Argo program has collected over two million temperature and salinity profiles from the upper 2 km of the ocean using an array of profiling floats. While challenges remain regarding sensor drift, quality control, and expanding the array, Argo has produced a valuable, high-quality dataset crucial for ocean and climate research and forecasting.
Explain Like I'm Five
Scientists used special robots to measure how warm and salty the ocean is really deep down, all around the world. This helps us learn more about our ocean and how the weather changes.
Possible Conflicts of Interest
KM and DM were employed by Sea-Bird Scientific, a company that manufactures CTDs used in Argo floats. The other authors declared no competing interests.
Identified Limitations
Rating Explanation
This is a comprehensive overview of a major scientific program, detailing its history, methodology, data quality, and future challenges. The program has produced a valuable dataset, and actively works to address identified limitations, improving methodology over time. The declared COI related to employees of a sensor manufacturer, while relevant, doesn't appear to unduly bias the paper. Overall, a valuable contribution, though not quite groundbreaking.
