Description: Well-founded data management systems are of vital importance for ocean observing systems as they ensure that essential data are not only collected but also retained and made accessible for analysis and application by current and future users. Effective data management requires collaboration across activities including observations, metadata and data assembly, quality assurance and control (QA\QC), and data publication that enables local and interoperable discovery and access and secures archiving that guarantees long-term preservation. To achieve this, data should be findable, accessible, interoperable, and reusable (FAIR). Here, we outline how these principles apply to ocean data and illustrate them with a few examples. In recent decades, ocean data managers, in close collaboration with international organizations, have played an active role in the improvement of environmental data standardization, accessibility, and interoperability through different projects, enhancing access to observation data at all stages of the data life cycle and fostering the development of integrated services targeted to research, regulatory, and operational users. As ocean observing systems evolve and an increasing number of autonomous platforms and sensors are deployed, the volume and variety of data increase dramatically. For instance, there are more than 70 data catalogs that contain metadata records for the polar oceans, a situation that makes comprehensive data discovery beyond the capacity of most researchers. To better serve research, operational, and commercial users, more efficient turnaround of quality data in known formats and made available through Web services is necessary. In particular, automation of data workflows will be critical to reduce friction throughout the data value chain. Adhering to the FAIR principles with free, timely, and unrestricted access to ocean observation data is beneficial for the originators, has obvious benefits for users, and is an essential foundation for the development of new services made possible with big data technologies.

Description: Marine data are needed for many purposes: for acquiring a better scientific understanding of the marine environment, but also, increasingly, as marine knowledge for decision making as well as developing products and services supporting economic growth. Data must be of sufficient quality to meet the specific users' needs. It must also be accessible in a timely manner. And yet, despite being critical, this timely access to known-quality data proves challenging. Europe's marine data have traditionally been collected by a myriad of entities with the result that much of our data are scattered throughout unconnected databases and repositories. Even when data are available, they are often not compatible, making the sharing of the information and data aggregation particularly challenging. In this paper, we present how the European Marine Observation and Data network (EMODnet) has developed over the last decade to tackle these issues. Today, EMODnet is comprised of more than 150 organizations which gather marine data, metadata, and data products and make them more easily accessible for a wider range of users. EMODnet currently consists of seven sub-portals: bathymetry, geology, physics, chemistry, biology, seabed habitats, and human activities. In addition, Sea-basin Checkpoints have been established to assess the observation capacity in the North Sea, Mediterranean, Atlantic, Baltic, Artic, and Black Sea. The Checkpoints identify whether the observation infrastructure in Europe meets the needs of users by undertaking a number of challenges. To complement this, a Data Ingestion Service has been set up to tackle the problem of the wealth of marine data that remain unavailable, by reaching out to data holders, explaining the benefits of sharing their data and offering a support service to assist them in releasing their data and making them available through EMODnet. The EMODnet Central Portal (www.emodnet.eu) provides a single point of access to these services, which are free to access and use. The strategic vision of EMODnet in the next decade is also presented, together with key focal areas toward a more user-oriented service, including EMODnet for business, internationalization for global users, and stakeholder engagement to connect the diverse communities across the marine knowledge value chain.

Description: Temperature and Salinity historical data collections covering the time period 1900-2013/2014 were created for each European marginal sea (Arctic Sea, Baltic Sea, Black Sea, North Sea, North Atlantic Ocean, and Mediterranean Sea) within the framework of SeaDataNet2 Project and they are available as ODV collections through a web catalog (https://www.seadatanet.org/Products/Aggregated-datasets). Two versions have been published and they represent a snapshot of the SeaDataNet database content at two different times: V1.1 (January 2014) and V2 (March 2015). A Quality Control Strategy (QCS) was developped and continuously refined in order to improve the quality of the database content and create the best data products. The QCS consists of four main phases: 1) data harvesting from the data infrastructure; 2) file and parameter aggregation; 3) secondary quality check analysis; 4) correction of data anomalies. The approach is iterative to facilitate the upgrade of the database content and it allows a versioning of data products. Regional temperature and salinity monthly climatologies have been produced from V1.1 historical data collections and they are also available (https://www.seadatanet.org/Products/Climatologies). Within the new SeaDataCloud Project the release of updated historical data collections and new climatologies is planned. SeaDataCloud novelties are the introduction of decadal climatologies at various resolutions, the development of climatologies for the Global Ocean and a task dedicated to new data products, like Mixed Layer Depth climatologies, Ocean Heat Content estimates, coastal climatologies from HF radar data. All SeaDataCloud products are available through a dedicated web catalogue together with their relative Digital Object Identifier (DOI) and Product Information Document (PIDoc) containing all specifications about product’s generation, quality assessment and technical details to facilitate users’ uptake. The presentation will briefly overview the existing SeaDataNet products and introduce the SeaDataCloud products’ plan, but the main focus will be on the first release (February 2018) of SeaDataCloud Temperature and Salinity historical data collections, spanning the time period 1900-2017, their characteristics in terms of space-time data distribution and their usability.

Description: A clean and healthy ocean can be achieved, restored and preserved through constant and systematic monitoring of the marine environment, which allows to understand its complex dynamics and exploit its natural recourses through a sustainable development approach. Marine monitoring is a complex and multidisciplinary activity that measures, evaluates and determines physical and biogeochemical parameters at multiple scales through a variety of sensors characterized by different accuracy. The management and long term preservation of the deriving marine data represents a societal priority which enables to assess the past and present ocean state, to predict its evolution and to understand/mitigate the impact of human activity and climate change on it.

Description: SeaDataNet is an EU funded project (2006 – 2011) to develop and provide a Pan-European infrastructure for marine & ocean data management. The project builds upon earlier data management infrastructure projects, undertaken over a period of 20 years by an expanding network of oceanographic data centres from the countries around all European seas. Its predecessor project Sea-Search had a strict focus on metadata. SeaDataNet maintains significant interest in the further development of the metadata infrastructure, but its primary objective is the provision of easy access to data and generic data products. SeaDataNet is a distributed infrastructure connecting 40 data centres from 35 countries around the Black Sea, Mediterranean, North East Atlantic, North Sea, Baltic and Arctic regions. These include: - National Oceanographic Data Centres (NODC’s) - Satellite Data Centres. The SeaDataNet portal has been set up at http://www.seadatanet.org and it provides a platform for all SeaDataNet services and standards. It includes a number of discovery services. A key service is the Common Data Index (CDI), based upon the ISO19115 metadata model. It gives detailed insight in available datasets at partners databases and provides an on-line shopping mechanism for direct ordering and downloading of datasets from distributed data centres, also taking into account data access restrictions and types of users. This SeaDataNet V1 system is technically operational and good progress is being made with interconnecting all 40 data centres from SeaDataNet. Interoperability is the key to distributed data management system success and it is achieved in SeaDataNet V1 by: - Using common quality control protocols and flag scale - Using controlled vocabularies from a single source that have been developed using international content governance - Adopting the ISO 19115 metadata standard for all metadata directories - Providing XML Validation Services to quality control the metadata maintenance, including field content verification based on Schematron. - Providing standard metadata entry tools - Using harmonised Data Transport Formats (NetCDF, ODV ASCII and MedAtlas ASCII) for data sets delivery - Adopting of OGC standards for mapping and viewing services - Using SOAP Web Services in the SeaDataNet architecture For the Black Sea region and the Caspian Sea region additional projects are underway, also funded by the EU. These projects are targeted at further developing regional data management networks, that give overview and access to locally managed datasets by services, interoperable with SeaDataNet. The Upgrade BlackSeaSCENE project started in 2009 and is successor to the previous BlackSeaSCENE project. It now engages 43 local institutes, that are adopting the SeaDataNet services and standards, to populate a regional infrastructure, harmonised with SeaDataNet. The NODCs from the Black Sea countries are leading the build up of national networks and act as linking pin for transfer of expertise and tools from the SeaDataNet network. A comparable development is on-going in the Caspian Sea region via the CASPINFO project, engaging 12 local institutes. IODE is partner in SeaDataNet, Upgrade BlackSeaSCENE and CASPINFO to ensure cohesion on a global scale and to support training and capacity building activities.

Description: The needs of society and the emerging blue economy require access and integration of data and information for the construction of dedicated products. A “transparent and accessible ocean” is one of the key objectives of the Ocean Decade 2021–30. In this context, marine infrastructures become significant components of a global knowledge environment, enabling environmental assessment and providing the necessary data for scientifically valid actions to protect and restore ocean health, to use marine resources in a sustainable way. The data is collected, analyzed, organized, and used by people and their good use/reuse can be obtained with social practices, technological and physical agreements aimed at facilitating collaborative knowledge, decision-making, inference. The vision is a digital ocean data ecosystem made up of multiple, interoperable, and scalable components. The huge amount of data and the resulting products can drive the development of new knowledge as well as new applications and services. Predictive capabilities that derive from the digital ecosystem enable the implementation of services for real-time decision-making, multihazard warning systems, and advance marine space planning. The chapter develops following the progressive complexity and information content of products deriving from oceanic data: data cycle and data collections, data products, oceanic reanalysis. The chapter discusses the new challenges of data products and the complexity of deriving them.
