Short summary

Ocean monitoring is crucial to understand the regular seasonality and the drift induced by climate change. Satellites offer a possibility to monitor the complete surface of the Earth within a few days with a harmonized methodology, reaching resolutions of few kilometres. We revisit traditional ship survey optical parameters such as the Secchi disk depth and the Forel–Ule index and derive them from satellite observations. Our time series is 21 years long and has global coverage.
