As a member of the salinity gradient assessment working group, ESR provides up-to-date ocean surface salinity gradient calculations derived from satellite and Argo data as well results for salinity gradient validation. The results are available to view and download.

Our goal is to provide a systematic estimation and assessment of satellite sea surface salinity gradients over the global ocean, including spatiotemporal variability, as well as regional analysis.
