Short summary
Satellites monitor ocean health by measuring plant pigments, but accuracy depends on reliable water samples. NASA analyzed nearly 20,000 ocean samples to assess measurement consistency. Most pigments met established quality standards. Variability was largest for rare pigments at low concentrations, reflecting natural ocean patchiness rather than instrument error. Rigorous quality controls support satellite validation, and improvements in field sample collection offer the most promising path.
