EMODnet (European Marine Observation and Data Network) is the long term marine data initiative supported by the European Commission since 2009 to ensure that European marine data will become easily accessible, interoperable, and free on restrictions on use. EMODnet Chemistry provides access to standardized, harmonized and validated chemical data collections for water quality evaluation at a regional scale, as defined by the Marine Strategy Framework Directive (MSFD). The data portal has adopted and adapted SeaDataNet standards and services, establishing interoperability between the data sets from the many different providers (more than 60 in EMODnet Chemistry network). Concentration maps of nutrients, chlorophyll-a and dissolved oxygen are computed on a standard grid, providing information at a regular time interval, per season and over several vertical layers, including the deepest one. Dedicated OGC standard services for browsing, viewing and downloading chemistry observation, data and data products for the European waters have been developed, and are actively maintained and monitored.

The Ocean Action Hub is an open, interactive website providing information and promoting action globally to support the implementation of SDG 14: Life below Water before 2030. The Hub was initiated by the United Nations Development Programme (UNDP), in partnership with the Governments of Sweden and Fiji, to facilitate multistakeholder engagement as part of the Ocean Conference process. The Hub hosted online discussions on ocean issues as an input into the development of the 1st Ocean Conference "Call for Action" in 2017, and facilitated co-development of solutions and voluntary commitments by multi-stakeholders, as well as providing a space for connecting and sharing ideas. In the run-up to the 2nd Ocean Conference the Hub continues to be maintained as a central source for information on implementation of SDG 14. The ocean plays a key role in the achievement of the 2030 Agenda for Sustainable Development. The ocean covers nearly three quarters of the Earth’s surface and contributes substantially to human development, including to the provision of food security, transport, energy supply, tourism and many of the planet’s most critical ecosystem services (carbon and nutrient cycling, climate regulation, oxygen production). The market value of marine and coastal resources and industries is approximately USD 3 trillion per year, or 5 percent of global GDP. Yet, today it is estimated that 40 per cent of our oceans are heavily affected by unsustainable practices, including over-fishing, land-based sources of pollution, habitat destruction, invasive species and climate change, particularly ocean acidification. SDG 14: Life below Water aims to address these threats.

The Knowledge Network for Biocomplexity (KNB) is an international repository intended to facilitate ecological and environmental research. The KNB was launched in 1998 with a grant from the National Science Foundation (NSF), with the purpose of being the long term home for synthesis datasets and research products generated by National Center for Ecological Analysis and Synthesis (NCEAS) working groups. Since then, NCEAS has continued to operate the KNB not only as an archive for NCEAS working group products, but also for the broader ecology and environmental science community. The KNB acceps all environmental or ecological related data and publishes datasets with Digital Object Identifiers for the express purpose of ensuring long-term access to these datasets. We strive to abide by FAIR (findable, accessible, interoperable, resuble) principles of data sharing and preservation. For scientists, the KNB is an efficient way to share, discover, access and interpret complex ecological data. Due to rich contextual information provided with KNB data, scientists are able to integrate and analyze data with less effort. The data originate from a highly-distributed set of field stations, laboratories, research sites, and individual researchers. The foundation of the KNB is the rich, detailed metadata provided by researchers that collect data, which promotes both automated and manual integration of data into new projects.

Seabed Habitats was one of seven themes of the European Marine Observation and Data Network (EMODnet) initiative, funded by the European Maritime and Fisheries Fund. Since its inception in 2009, EMODnet Seabed Habitats developed, improved and gradually increased the coverage of a broad-scale seabed habitat map for Europe's seabed, also known as EUSeaMap. In addition, EMODnet Seabed Habitats continued the work started by MESH and MESH Atlantic projects in collating and making available seabed habitat maps from surveys, through the EMODnet Seabed Habitats map viewer. In it's third Phase (2017-2019), EMODnet Seabed Habitats collated and provided habitat point data and the outputs of habitat distribution modelling, and the third phase has now been extended to 2021. The extended third phase of the project will: - Continue to grow Europe's only comprehensive library of habitat maps from surveys and collection of survey sample points - Create new composite data products to add to those for the Essential Ocean Variable habitats and OSPAR threatened and/or declining habitats - Update the EMODnet broad-scale seabed habitat map for Europe (EUSeaMap) using the next seabed substrate update from EMODnet Geology - Update web content with extra resources for habitat mapping, including a catalogue highlighting all the most useful data products

NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) is located at NASA's Jet Propulsion Laboratory in Pasadena, California. PO.DAAC manages and provides tools and services for NASA's oceanographic and hydrologic data (satellite, airborne, and in-situ) to enable a greater understanding of the physical processes and conditions of the global ocean. Measurements include gravity, ocean winds, sea surface temperature, ocean surface topography, sea surface salinity, and circulation. The data support a wide range of applications including climate research, weather prediction, resource management, policy, and the stewardship of ocean data resources.

Built and developed by researchers, to ensure that everyone can join in Open Science. The OpenAIRE project, in the vanguard of the open access and open data movements in Europe was commissioned by the EC to support their nascent Open Data policy by providing a catch-all repository for EC funded research. CERN, an OpenAIRE partner and pioneer in open source, open access and open data, provided this capability and Zenodo was launched in May 2013. In support of its research programme CERN has developed tools for Big Data management and extended Digital Library capabilities for Open Data. Through Zenodo these Big Science tools could be effectively shared with the long­-tail of research. Zenodo helps researchers receive credit by making the research results citable and through OpenAIRE integrates them into existing reporting lines to funding agencies like the European Commission. Citation information is also passed to DataCite and onto the scholarly aggregators.

EMODnet Biology provides three keys services and products to users. 1)The data download toolbox allows users to explore available datasets searching by source, geographical area, and/or time period. Datasets can be narrowed down using a taxonomic criteria, whether by species group (e.g. benthos, fish, algae, pigments) or by both scientific and common name. 2) The data catalogue is the easiest way to access nearly 1000 datasets available through EMODnet Biology. Datasets can be filtered by multiple parameters via the advanced search from taxon, to institute, to geographic region. Each of the resulting datasets then links to a detailed fact sheet containing a link to original data provider, recommended citation, policy and other relevant information. Data Products - EMODnet Biology combines different data from datasets with overlapping geographic scope and produces dynamic maps of selected species abundance. The first products are already available and they focus on species whose data records are most complete and span for a longer term.
