A world deep displacement dataset, named ANDRO, after a traditional dance of Brittany meaning a swirl, comprising more than 1300 000 deep displacements, has been produced from the Argo float trajectory data ('traj' files). ANDRO dataset was completed over the period 2000-2009, then was partially but yearly updated since 2010. For detailed information and status of the last released ANDRO product, please visit the dedicated Argo France web page: https://www.umr-lops.fr/SNO-Argo/Products/ANDRO-Argo-floats-displacements-Atlas One important feature of ANDRO is that the pressures measured during float drifts at depth, and suitably averaged are preserved in ANDRO. To reach this goal, it was necessary to reprocess most of the Argo raw data, because of the many different decoding versions (roughly 100) not always applied by the DACs to the displacement data because they were mainly interested in the p,t,S profiles. The result of our work was the production of comprehensive files, named DEP (for 'déplacement' in French), containing all the possibly retrievable float data.

The In Situ Analysis System (ISAS) has been developed to produce temperature and salinity fields that preserve as far as possible the time and space sampling capabilities of the Argo float network. Since the first global analysis in 2009, the system has been extended to take into account all types of vertical profiles and time series, as well as new parameters such as dissolved oxygen produced by BGC Argo. ISAS gridded fields are based entirely on in situ measurements. The system aims to monitor the evolution of ocean properties as a function of time for climatological studies, and to enable easy calculation of climate indices. Delayed-time processing of the 2002-2020 dataset has been carried out using ISAS-V8 and the updating of a priori statistics. Note that ISAS-V8 has been implemented as an operational analysis tool at the Coriolis data center since June 2020.
