MAP-IO (Marion Dusfresne Atmospheric Program - Indian Ocean) flow cytometry_part2

The MAP-IO (Marion Dusfresne Atmospheric Program - Indian Ocean) program aims to address the lack of observations in this region of the Earth by equipping the Marion Dufresne vessel (https://taaf.fr/en/marion-dufresne-and-astrolabe/) with a set of in-situ instruments and remote sensing equipment for atmospheric and marine biology studies. This program has been labelled by the French Commission Nationale de la Flotte Hauturière (CNFH, https://www.flotteoceanographique.fr/) for the periods 2021-2024 and 2024-2027. Since 1st January 2025, it has integrated the Instrument National CNRS with ACTRIS research infrastructure. More information on the project can be found here: http://www.mapio.re/.  MAP-IO is a scientific program led by the University of La Reunion (LACy and OSU-R) and was funded by the European Union through the ERDF programme, the University of Reunion, the SGAR-Réunion, the Région Réunion, the CNRS, IFREMER and the Flotte Océanographique Française. The Cytosense automated flow cytometer from the cytobuoy compagny was installed onboard the Marion Dufresnes Sea Water supply, to run semi continuously samples for phytoplankton functional groups resolution. A detailed description can be found in (Pierre Tulet et al., 2024 https://doi.org/10.5194/essd-16-3821-2024). Sample acquisition was scheduled once every two hours. The data set includes for each functional group identified, the abundances in cells/ml. The groups are identified as standard groups following the BODC F02 vocabulary (http://vocab.nerc.ac.uk/collection/F02/current/).
