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.

The Copernicus Marine Service (or Copernicus Marine Environment Monitoring Service) is the marine component of the Copernicus Programme of the European Union. It provides free, regular and systematic authoritative information on the state of the Blue (physical), White (sea ice) and Green (biogeochemical) ocean, on a global and regional scale. It is funded by the European Commission (EC) and implemented by Mercator Ocean International. It is designed to serve EU policies and International legal Commitments related to Ocean Governance, to cater for the needs of society at large for global ocean knowledge and to boost the Blue Economy across all maritime sectors by providing free-of-charge state-of-the-art ocean data and information. It provides key inputs that support major EU and international policies and initiatives and can contribute to: combating pollution, marine protection, maritime safety and routing, sustainable use of ocean resources, developing marine energy resources, blue growth, climate monitoring, weather forecasting, and more. It also aims to increase awareness amongst the general public by providing European and global citizens with information about ocean-related issues.

The Marine Environmental Data and Information Network (MEDIN) is a partnership of UK organisations committed to improving access to UK marine data. MEDIN is open to all with an interest in marine data and information. We are sponsored by a consortium of 15 sponsors and partnered with over 50 organisations. MEDIN Sponsors include a range of UK marine organisations who support MEDIN’s principles and lead the UK in marine data management. To officially join the network and become a MEDIN Sponsor, please email MEDIN stating your interest at enquiries@medin.org.uk. Our partners represent government departments and agencies, research organisations and private companies and have committed to practise good data management to help future-proof and secure UK’s valuable marine data. MEDIN reports to the Marine Science Coordination Committee. The MEDIN portal contains information about 15,000 marine datasets. The United Kingdom Directory of Marine Observing Systems (UKDMOS), is a unique internet-based searchable database of marine monitoring conducted by UK organisations. Aiming to fulfil the basic requirement to know where, when and what is being monitored in the marine environment around the UK and provide information to help coordinate monitoring across different organisations, UKDMOS is a tool for searching monitoring programmes and series based on information such as the parameters measured or the frequency of measurements taken. UKDMOS is managed and updated by the Marine Environmental Data and Information Network (MEDIN).

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

Stakeholder networks from 32 countries united to collaborate on Ocean Action, Climate Action, addressing pollution from land-based, riverine and marine-based sources and advancing Circular Economy development. International Waste Platform provides international expertise and launches joint initiatives; It supports advancing solutions to mitigate the global waste, plastic pollution & climate crises which are interlinked. Representatives committed themselves to align objectives, to support the implementation of strategies of Ocean Action and Climate Action, as well as to share ideas, best practices, concepts, programs, knowledge and opportunities; including the reduction of plastic debris at the source, before it enters rivers and the coastal environment. Country / regional networks and national marine debris networks make a difference in societal behaviour change and environmental policies by providing input and promoting action which aims at finding solutions to reduce (ocean) plastic pollution. Country and regional networks are instrumental to reach the prevention and reduction of marine pollution, facilitate and foster the establishment of national and international partnerships in a multi-stakeholder approach.

The ODIS "Catalogue of Sources" aims to be an online browsable and searchable catalogue of existing ocean related web-based sources/systems of data and information as well as products and services. It will also provide information on products and visualize the landscape (entities and their connections) of ocean data and information sources. It will contribute to the objectives of the Agenda 2030, and in particular the UN Decade for Ocean Science for Sustainable Development. The Catalogue is not an ocean database or metadata repository. The catalogue includes descriptive information such as the URL, title, description, language, point of contact, geographic scope, available technologies for machine-to-machine interaction, keywords, etc. and can be searched on many of these fields. The IODE network of NODCs has been collecting, managing and serving data for decades. This effort has yielded an extensive, but distributed and heterogeneous collection of data and information sources. Additionally, the low threshold for technical capabilities required to offer data and information over the Internet means that many of the hosted resources are not readily discoverable through NODCs, regional or international data and information systems ODIS will provide an online catalogue of (ideally) all online data/information sources (and, where possible, metadata on off-line sources as well). Many regional and international programmes and projects have developed online data/information services but there is currently no "one-stop shop" where users are offered an overview and/or common data/information discovery interface. There are currently 3090 sources (2172 are searchable) catalogued in the system.

The Western Channel Observatory (WCO) is an oceanographic time-series and marine biodiversity reference site in the Western English Channel. In situ measurements are undertaken weekly at coastal station L4 and fortnightly at open shelf station E1 using the research vessels of the Plymouth Marine Laboratory and the Marine Biological Association. These measurements are complemented by PML's recognised excellence in ecosystem modelling and satellite remote sensing science. By integrating these different observational disciplines we can begin to disentangle the complexity of the marine ecosystem. The WCO measures several key parameters important to the functioning of the marine ecosystem such as light, temperature, salinity and nutrients. Station L4 has some of the longest time-series in the world for zooplankton and phytoplankton, and fish trawls have been made by the MBA for a century. Station E1 has a hydrographic series dating from 1903. These long series are complemented by hourly measurements made at our moorings situated at both stations. These can elucidate changes not captured by the routine weekly sampling.

The Ocean Data Viewer offers users the opportunity to view and download a range of spatial datasets that are useful for informing decisions regarding the conservation of marine and coastal biodiversity. These decisions ultimately affect the ocean's health and productivity, which provide the ecosystem services that are necessary for our well-being, livelihoods, and survival. To date, the users of this tool have included government agencies, scientists, researchers, the corporate sector, and non-governmental organisations. These data come from internationally respected scientific institutions and other organisations that have agreed to make their data available to the global community, with the hope that these data will support and encourage informed decision-making that sustains global biodiversity and ecosystem services. The Ocean Data Viewer is primarily a mechanism to view and download data, and is not intended to be used for analysis or to query data.
