Despite technological advances in reducing the size and consumption of electronic components, in providing powerful energy through Lithium batteries, and in reducing the size of sensors, the new generation of stand-alone instruments such as Ocean Bottom Seismometers (OBS) cannot be deployed on average for more than a year on the seafloor andprovide access to their data only upon their recovery. Any long-term monitoring thus implies multiple cruises and redeployments. Permanent observatories with real-time access to data require ambitious cabled-to-shore sensors and infrastructures. Here we propose an alternative solution bridging the gap between these two endmembers, consisting of multi-parameter platforms for seafloor (MUG-OBS) or water-column (HYDROBS) observations, and offering a lifespan offour years and an access to the collected data through data-shuttles releasable on demandfrom a surface ship. specialized ANTILLES EQUATEUR 066GPHMAR en ligne [8 ] Piscataway IEEE 2019 OCEANS 2019 : Marseille Conference, Marseille (FRA), 2019/06/17-20 https://www.documentation.ird.fr/hor/fdi:010090464 10.1109/OCEANSE.2019.8867216 978-1-7281-1450-7 [F B010090464] https://www.documentation.ird.fr/hor/fdi:010090464 https://www.documentation.ird.fr/intranet/publi/2023-10/010090464.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-10-10 2025-02-24 fdi:010090464 fre
