Notice from SBE on pressure calibration error
Argo will stop sending TESAC messages on the GTS on 2 July, 2018
Thereafter, only BUFR messages will be sent on the GTS
Deep Argo pilot data enters the Argo data stream
As part of pilot deployments, Argo profiles reaching below 2000dbar will start appearing in the Argo data system. The accuracy of the data below 2000dbar is not yet well understood and so Argo is currently labelling these data with lower quality flags (2 and 3) in real time. We warn users to treat these data with care and recognize that we … Read More

Advice on pressure biases in the Argo data set
A part of the global Argo data are subject to biases in reported pressures. These biases are usually less than 5db, but occasionally can be larger (> 20db). These bias errors are being steadily removed by the reprocessing of historical Argo data. We expect that by the end of 2010 these errors will be removed from the global Argo data … Read More
Notice 1: problem with SBE CTD pressure sensors on Argo floats, recommendation to stop float deployments and return CTDs to Sea-Bird for repair
Dear Argo colleagues, As many of you are aware, we have been working to understand the details of a problem with the Druck pressure sensors used in SBE-41 and SBE-41CP CTDs on Argo floats. The name given to the problem is “Druck micro-leaks” because in 3 instances, in the last two years, we have identified that oil from the sealed … Read More
