The SOCIB Data Management Plan (DMP) template was established after reviewing the approaches followed by key players and initiatives of interest for SOCIB (e.g. IODE, ORD, ANDS, IMOS, NANOOS). This template outlines the various steps of the data flows for platforms in relation to each facility. It also identifies the roles in the data flow as well as the definitions of the formats, naming conventions and products. After our experience with the existing DMPs we decided to evaluate how it aligns to the international standards as well as how it responds to the internal needs of SOCIB. The SOCIB DMP template describes the data management life cycle for the ocean data, collected, processed and/or generated by SOCIB, making data FAIR. It also includes the data curation, preservation and the description of the data flows from SOCIB to the main European marine data portals such as, CMEMS-INSTAC, SeaDataNet and EMODnet. The objective of this DMP is to improve the day-to-day handling of the SOCIB data, creating a more transparent, collaborative, and sustainable communication system both internally and with the end users. This approach seeks the convergence and the alignment with the main actors in the global scene, also assuring the implementation of Ocean Best Practices (OBPs) procedures across the value chain. Furthermore, recommendations provided by DIGITAL CSIC are followed, and this has enhanced SOCIB’s data integration in CSIC repository, pursuing a greater impact of research results to address future challenges. This document also benefits from the participation and achievements from EU and international initiatives and projects (e.g. CMEMS-In Situ TAC, JERICO-S3, JERICO-DS, EuroSea and Calypso) with regard to data management and the building of an integrated data system. It is in particular aligned with the ongoing efforts in JERICO-S3 and the related DMP for coastal platforms. The aim is therefore to promote data management and its application in Europe, seeking convergence among the recommendations from the EuroGOOS Data Management, Exchange, and Quality Working Group (DATAMEQ). The template aims to meet the requirements of different observing programs and platforms with the necessary flexibility and adaptability allowing the stakeholders to design a customised workflow, responding to their needs.
