Message to Argo users about an increased occurrence of salinity errors in the real time Argo data stream

Due to a manufacturing problem that occurred a few years ago, a larger than normal number of SeaBird Scientific CTD cells (SNs 6000 - 7100) used in Argo developed a high salinity bias within 2 years of deployment. Many of these CTDs are still active in Argo, and as result, a higher portion than normal of Argo real time data are subject to salinity errors larger than Argo’s 0.01 accuracy target.
