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 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.

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 World Bank Group works in every major area of development. It provides a wide array of financial products and technical assistance, and it helps countries share and apply innovative knowledge and solutions to the challenges they face.

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.

Explore global fisheries and aquaculture. Understand their status and how impacts are being managed. Learn what improvements are underway, and see what actions seafood stakeholders can take to drive sustainability. FishSource is a publicly available online resource about the status of fisheries, fish stocks, and aquaculture. FishSource compiles and summarizes publicly available scientific and technical information and presents it in an easily interpretable form. FishSource was created in 2007 by Sustainable Fisheries Partnership to provide major seafood buyers with up-to-date, impartial, and actionable information on the sustainability of fisheries and the improvements they need to make to become more sustainable. In 2018, information on aquaculture sources was added to the database to provide FishSource users with a more robust tool that covers all types of seafood production. Although the primary intended audience of FishSource is seafood businesses, other audiences - such as academics, researchers, and non-profit organizations - have also become frequent and welcomed users of FishSource. The information on FishSource is primarily developed and updated by a small team of in-house analysts, but their capacity is recognizably insufficient to maintain complete coverage of all global fisheries. As such, profiles may be incomplete or information may be out of date. The seafood industry and external contributors are invited to help fill any gaps that they consider priorities through our Rapid Assessment Program. FishSource always welcome comments on any of our profiles and encourage an open debate on the sources of information used and our interpretation of the data. Our objective is to use only publicly available sources and fully credit those sources, effectively acting as an inventory of information sources on fisheries and aquaculture.

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.
