| Abstract: | Several floats that deployed by different countries during the last years over the global ocean, which served as a contribution to the Array for real time geostrophic oceanography (Argo), are studied in this paper with respect to their uniqueness in the Delayed Mode Quality Control (DMQC) process. Of these floats, issues were found in the temperature-salinity relationships during the DMQC, which would easily be misinterpreted or overlooked. This study lists and summarizes the possible situations of the floats that might confront in their observation life, together with the reasonable explanations. The authors present some thoughts on evaluating the performance of the conductivity sensors and calibrating the float salinity data. |
