Magnetic data of the ridge axis of Mohn's ridge (NE Atlantic) in order to study the mecanisms of the oceanic accretion.

Geophysical and geochemical study of the Pacific-Antarctic ridge between S65/W175 and S60/W150. The first objective was to contribute to the understanding and modelling of the mechanisms of ocean ridge functioning on the scale of the basic accretion unit (< 100 km). The second was to study the zoning of the upper mantle on various scales, through investigating the geochemical signature of rocks from the axial valley. This cruise falls under the framework of the Inter-Ridge programme and is the result of cooperation between IFREMER/DRO/GM, INSU (CNRS,IPG, GRGS), Washington State University, Scripps (University of California) and the University of Chiba (Japan).

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.
